Ectoderm
The ectoderm is the outer layer of the early embryo. It emerges first and forms from the outer layer of germ cells.
Generally speaking, the ectoderm differentiates to form the nervous system (spine, peripheral nerves and brain) , tooth enamel and the epidermis (the outer part of integument). It also forms the lining of mouth, anus, nostrils, sweat glands, hair and nails.
In vertebrates, the ectoderm has three parts: external ectoderm (also known as surface ectoderm), the neural crest, and neural tube. The latter two are known as neuroectoderm.

In 1995, the group released its second album, E. 1999 Eternal, which included hits "1st of tha Month" and "Tha Crossroads." A tribute to the recently deceased Eazy-E, "Tha Crossroads," won a Grammy award in 1997. The Art of War, the group's third album, was also released in 1997.
Bone Thugs released two more albums that did not generate as much hype: BTNHResurrection (2000) and Thug World Order (2002). The group went on hiatus and returned in 2007 with Strength & Loyalty, this time released by Swizz Beatz's label Full Surface Records. Bone Thugs-n-Harmony officially returned with their new album , released in 2010 by their own record label, BTNH Worldwide, with distribution by Warner Bros.
Early years
Formed in 1991, the group consisted of only four members: Krayzie Bone, Layzie Bone, Bizzy Bone and Wish Bone, and the group was originally called B.O.N.E Enterprise. Their first album, Faces of Death, was recorded in 1993. With new member and Layzie's brother, Flesh-n-Bone who was a member of the Crips, added the same year, the group renamed itself Bone Thugs-n-Harmony. In November 1993, the group auditioned backstage for rapper Eazy-E, who was performing in Cleveland with his father. After a second audition, Eazy-E signed the group to his label Ruthless Records.Ruthless Records
Creepin on ah Come Up
Released in June 1994, the EP Creepin on ah Come Up, was Bone Thugs-n-Harmony's debut with Ruthless. Peaking at #12 on the Billboard 200 album chart and #2 on the Top R&B;/Hip-Hop Albums chart, it included the hit singles "Thuggish Ruggish Bone" and "Foe tha Love of $", the second of which featured a verse by Eazy-E. "Thuggish Ruggish Bone" peaked at #22 on the Billboard Hot 100 chart and #2 on the Hot Rap Tracks chart, and "Foe tha Love of $" peaked at #41 on the Hot 100 and #4 on the Rap Tracks.E. 1999 Eternal
In 1995, the group's second album E. 1999 Eternal was released. It included the singles "1st of tha Month", which peaked at #14 on the Hot 100 and #4 on the Hot Rap Tracks, and "Tha Crossroads", which reached #1 on the Hot 100 and Hot Rap Tracks charts. The album name originated from Eazy-E's album, Eternal E, naming it after Eazy-E's album was just another way of showing respect and tribute to the rapper that helped make them big. In the same year, Flesh-n-Bone would become the first member of the group to release a debut album entitled T.H.U.G.S.The Art of War
In 1997, the group released the double-disc set The Art of War. The single "Look into My Eyes" appeared on the soundtrack of the film Batman & Robin. It peaked at #4 on the Hot 100 and #2 on the Hot Rap Tracks chart. Pleading guilty, Flesh-n-Bone was sentenced to 11 years in prison. Bizzy Bone abstained from promoting BTNHResurrection because he felt that Ruthless Records owed him money. He dropped a million-dollar lawsuit he filed against Sony Music and Loud Records in exchange for a termination of his Sony contract. Three members of Bone Thugs-n-Harmony released solo albums in 2001: Bizzy Bone with The Gift, Layzie Bone with Thug by Nature, and Krayzie Bone with Thug on da Line.Thug World Order
In 2002, the group released Thug World Order. The album debuted at #12 on the Billboard 200,After Ruthless
Thug Stories
Thug Stories, Bone Thugs-n-Harmony's sixth album, was recorded on Koch Records and released on September 19, 2006. It marked the first time Bone Thugs-n-Harmony recorded as a trio. Thug Stories sold 38,000 in its first week and peaked at #25 on the Billboard 200 and #1 on the Independent Album Chart.Strength & Loyalty
Originally to be called The Bone Thugs Story, Strength & Loyalty was released on May 8, 2007. Being their first major album after an absence of nearly five years, the album debuted at #2 on the Billboard 200 and #1 on iTunes and the Billboard Urban Music charts. The album contains guest appearances by Mariah Carey, The Game, will.i.am, Akon, Twista, Bow Wow, Yolanda Adams, and Felecia.Producers on the album included Swizz Beatz, Akon, Pretty Boy & Bradd Young, DJ Toomp, Jermaine Dupri, will.i.am, and others. The executive producer of the album was Swizz Beatz. The first single was "I Tried", which was their first top 10 hit in 10 years, having peaked at number 6 on the U.S. Billboard Hot 100. The second single was "Lil Love", which failed to reach the success of their first single. The album has been certified Gold by the RIAA.
T.H.U.G.S.
T.H.U.G.S. is an album featuring previously unreleased, largely remixed Bone Thugs-n-Harmony songs that didn't make the final cut of BTNHResurrection and Thug World Order albums. It was released on November 13, 2007 by their former record label, Ruthless Records. The sole single off the album was "Young Thugs", which was accompanied by a newly-filmed music video featuring Krayzie, Layzie, Bizzy and Wish.I Tried (The Bone Thugs Movie)
Bone has also released a movie titled I Tried(directed by Rich Newey), which was originally named "What If..." The topic of the movie is how different the lives of Krayzie, Layzie and Wish would have been if they had never met Eazy-E. The movie was released in stores on September 25 of 2007. It has since become a platinum selling DVD.Reunion
In November 2007, Layzie Bone confirmed that he had completed the Bone Brothers III album with Bizzy Bone, spurring speculation of a full Bone reunion. In a video interview, Krayzie Bone stated that they all wanted to reunite but that record label issues may prevent an official reunion. Bizzy Bone had attended a Bone Thugs performance during the time and he and the three then-standing members had a "good conversation".After nearly a decade of incarceration, Flesh-n-Bone was released from prison on July 13, 2008. In an interview, Bizzy confirmed his return to the group, after them all getting together by the time of Flesh's release.
Uni5: The World's Enemy
video. A third single, "Meet Me in the Sky", was released on March 22. Uni-5: The World's Enemy was released on May 4, 2010.E.1999 Eternal Tour and New Record Deal
In the fall of 2010, the group went on their E.1999 Eternal Tour, a 36-city tour performing songs from their 1995 album E 1999 Eternal with a live band (without Bizzy). Bone will spend the rest of 2010 recording a new CD for a soon-to-be-disclosed new label deal, writing a book, and developing a film project based on their unique story.Style and technique
Bone's style and technique can be described as melodic, rapid-fire and aggressive. Their flow is often interwoven at a high-speed, melodic pace or slow, harmonic pace. They also tend to ride the beat that they're rapping over. Sometimes there are very few choruses separating their verses from one another. In the beginning, circa Faces of Death, Bone used a pseudo-Jamaican patois delivery with their trademark style, though they rarely do this now. Bone's subject matter has both spiritual and occult undertones (e.g., "Hell Sent", "Intro", "Mr. Ouija", "Mr. Ouija 2" and "Da Introduction"). At first, their subject matter was almost always exclusively about violence and smoking marijuana. Today, however, their subject matter includes other topics such as urban socio-political issues, their old friend and mentor Eazy-E and religion. Besides minor changes to subject matter and sound, their lyrical style, elocution, and overall methodology remain intact.Discography

Check us out at www.tutorvista.com Budding in hydra has received the attention of only a few investigators. Our principal information as to the origin of the bud is derived from Lang's' account. He describes the bud as beginning by an increase in volume and division of the interstitial cells. After the ectoderm becomes thickened, the mesoglea dis appears and the cells pass from the ectoderm into the endoderm. This process continues until the ectoderm becomes reduced to its normal thickness. The mesoglea then reforms and a cavity ap pears in the thickened endoderm, which becomes the enteron of the new individual. The main object of the present paper will be to give a brief account of the origin and development of the buds in hydra, more especially their manner of growth and what cells contribute most to their rapid formation. The species studied, Hydra viridis and Hydra sp.? (Brauer) differ somewhat from Lang's account. The mesoglea does not disappear and the ectodermal cells do not pass into the endoderm. The bud, however, begins by an increase in volume and division of the interstitial cells. After they have increased once or twice in volume, as shown in Fig. i, there is a slight outbulging of the ectoderm, which is scarcely perceptible. represents the condition of the interstitial, ectodermal and endodermal cells in the origin of the bud as they appear more highly magnified.

New bones form, but not too fast. The cells responsible for this are called the osteoblasts. Osteoblasts increase during maturation, But that number decreases through the generations. As bone degrades, osteoclasts remove old bone tissue, But because of equilibration this is not an issue. Osteoblasts and osteoclasts work together, Work together.

How your baby's growing: Deep in your uterus your embryo is growing at a furious pace. At this point, he's about the size of a sesame seed, and he looks more like a tiny tadpole than a human. He's now made up of three layers — the ectoderm, the mesoderm, and the endoderm — which will later form all of his organs and tissues. The neural tube — from which your baby's brain, spinal cord, nerves, and backbone will sprout — is starting to develop in the top layer, called the ectoderm. This layer will also give rise to his skin, hair, nails, mammary and sweat glands, and tooth enamel. His heart and circulatory system begin to form in the middle layer, or mesoderm. (This week, in fact, his tiny heart begins to divide into chambers and beat and pump blood.) The mesoderm will also form your baby's muscles, cartilage, bone, and subcutaneous (under skin) tissue. The third layer, or endoderm, will house his lungs, intestines, and rudimentary urinary system, as well as his thyroid, liver, and pancreas. In the meantime, the primitive placenta and umbilical cord, which deliver nourishment and oxygen to your baby, are already on the job.
Creation and the Singularity
Genetic Scienpology: After partially maturing....segmentation The End Times Gametes Game ZYGOTE : A BAS YOKE WHERE IN THE BIG EZ "OUT GOES THE Y CHROMOSOME" Zygote, in biology, a cell formed by the union of male and female gametes; a fertilized egg cell; earliest stage of development, preceding embryonic and fetal stages. Fertilization takes place when a free-swimming spermatozoon (sperm cell) penetrates the ovum's protective outer layer. Once this has happened, no other sperm has an effect on the fertilized egg, or zygote. Soon after fertilization, however, the egg and sperm nuclei merge to form a zygote with the proper number of chromosomes. At the same time cleavage, a series of consecutive cell divisions (mitoses), is initiated. (See bank tellers and talking heads on TV news) Cleavage produces a rapidly increasing number of cells smaller than the zygote. The patterns of cleavage vary, in part because of variations in the amount and distribution of yolk. In mammals, with small amounts of yolk, cleavage results in a hollow ball, the blastula. As the cells continue to multiply, the various regions of the ball fold and shift in position. In this manner three distinct layers develop. These are known as the primary germ layers. The primary germ layers form quite early in embryogeny. They appear, for example, during the 16th day of human embryonic development. The outermost layer is called the ectoderm; the innermost, the endoderm. Between these two layers lies the mesoderm <b>...</b>

Comb Jellies Known commonly as the sea walnut, these jellies are oval in shape and have tiny rows of comb-like plates running down their bodies. As they swim, these plates diffract (or bend) light to produce a shimmering, rainbow effect. Did you know? Comb jellies lack stinging cells. www.mysticaquarium.org Ctenophores are usually colorless and transparent, although some species are known to have red, black, orange or golden pigmentation. They mostly grow between a size of few centimeters to a foot and half long. Ctenophores tend to have a rainbow effect on the surface of their bodies, even though they are not bioluminescent. The body of the ctenophores is made up of two layers, the ectoderm (the outer layer) and the gastroderm (the inner layer. The ectoderm is a double layer of cells covered in a mucus-like substance that is secreted by special glands. The gastroderm contains a small cavity that is the stomach and is connected to the mouth with a long gullet. The gullet contains strong enzymes to help digest the food, so that by the time the food reaches the stomach, it is already half digested. The food gets fully digested in the stomach and the waste product is expelled from the body through the mouth itself, and sometimes, through two anal pores that are used very infrequently. The space in between the two layers is filled with a jelly like layer, the mesoglea.

Ctenophores Although known as comb jellies and endowed with delicate gelatinous tissue like cnidarian jellies, ctenophores are only very distantly related to hydromedusae and scyphomedusae. Unlike the true jellies (cnidarians), comb jellies lack stinging nematocysts and have developed other strategies, such as sticky tentacles and oral lobes to capture prey. The ctenophore body exhibits bi-radial symmetry (with an underlying bilateral symmetry), which is a bit different than the radial symmetry typical of cnidarian medusae. The signature characteristic of ctenophores are the comb rows. Formed by plates of closely-spaced cilia that are fused at the bases, comb rows beat in a wave pattern that moves from the aboral to the oral end. Comb jellies are the largest of all animals that utilize the beating of cilia for locomotion. It doesn't stop there - with lengths up to 2 mm, ctenophore cilia are the longest of any known. Each single comb within a row is made up of several thousand cilia, and each row may have dozens of combs, so an individual ctenophore is endowed with many thousands of cilia. All adult ctenophores possess eight comb rows, which easily distinguish them from any other type of gelatinous animal. A strikingly beautiful shimmering rainbow pattern is produced by the diffraction of light passing between the cilia. Most ctenophores are capable of bioluminescence, which is quite faint and only visible in darkened conditions. The dim glow is typically confined to the <b>...</b>

Check us out at www.tutorvista.com Animal tissues can be grouped into four basic types: connective, muscle, nervous, and epithelial. Multiple tissue types comprise organs and body structures. While all animals can generally be considered to contain the four tissue types, the manifestation of these tissues can differ depending on the type of organism. For example, the origin of the cells comprising a particular tissue type may differ developmentally for different classifications of animals. The epithelium in all animals is derived from the ectoderm and endoderm with a small contribution from the mesoderm which forms the endothelium. By contrast, a true connective tissue is present only in a single layer of cells held together via occluding junctions called tight junctions, to create a selectively permeable barrier. This tissue covers all organismal surfaces that come in contact with the external environment such as the skin, the airways, and the digestive tract. It serves functions of protection, secretion, and absorption, and is separated from other tissues below by a basal lamina. Endothelium, which comprises the vasculature, is a specialized type of epithelium.

In the Evolution of the metazoan animals, the Cnidaria, for example represented by the jellyfish, are the first animal group, having a real cell tissue, consisting of entoderm and ectoderm. These are important characters that newly evolved in the stem-species of cnidaria and ctenophora + Bilateria. Such characters are called "apomorphies". When we look at the tree of the Animalia, which represents a very well founded reconstruction of relationships within the animals, we can see that the evolution of life happened step by step by character transformations. Due to genetic variability and natural selection, new characters evolve. Evolution is the basis of the biodiversity all over the earth.
