The T lymphocytes capable of killing invading cellular organisms such as bacteria, protists, or fungi are cytotoxic T cells also known as CD8+ cells. These cells are capable of recognizing whether a cell has a major histocompatibility complex I (MHC I) surface protein or not. Those with absent MHC I surface protein will be killed by the cytotoxic T cells. Those with the MHC I surface protein expressing an invading antigen will also be killed by cytotoxic T cells. Those with the MHC I surface protein without an antigen will be spared by the cytotoxic T cell.
An animal body plan that is triploblastic and coelomate has three main layers of tissue during development.
<span>The germ layers are tissue layers which develop early in embryonic life, through the process of gastrulation. During gastrulation, a hollow cluster of cells-blastula reorganizes into two primary germ layers: an inner layer- endoderm, and an outer layer, - ectoderm which interact to produce a third germ layer - mesoderm. Together, the three germ layers will give rise to every organ in the body. For example, ectoderm will form skin, endoderm will form digestive tract and mesoderm will be involved in the formation of visceral organs like the stomach.</span>

Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes. This picture of the human chromosomes lined up in pairs is called a karyotype.
Of the 23 pairs of chromosomes, the first 22 pairs are called "autosomes." The final pair is called the "sex chromosomes." Sex chromosomes determine an individual's sex: females have two X chromosomes (XX), and males have an X and a Y chromosome (XY).
