Answer:
Epithelial Tissue
Explanation:
The epithelial tissue can be classified according to the amount of layers, such as <u>simple epithelium</u> (formed by a single cell layer) or <u>stratified epithelium</u> (formed by more than one cell layer).
In addition, this tissue is avascular, in other words, it has no proper blood supply. Its nutrient transport usually occurs by <u>diffusion</u> through connective tissue.
The epithelium layers are able to regenerate quickly and easily when destroyed. Being a coating tissue, its cells have high healing power.
The epithelial tissue has two opposite sides, the outside of the epithelium(cavity), is known as the <u>apical surface</u>, and the inside is called the <u>basal surface</u> (this surface receives nutrients from the connective tissue by diffusion).
Cells on both surfaces are tightly connected, providing protection to the underlying connective tissue.
Finally, epithelial tissue also participates in the process of absorption of substances through the <u>intestinal epithelium</u>.
Division into daughter cells indicate that the type of sexual reproduction that occurred is fission.
When budding happens, a bubble-like formation grows on the parent cell and develops then breaks away. In fragmentation, the parent organisms breaks into fragments, as the name suggests, and each piece becomes a new organism.
1.) Mitosis is the splitting of a parent cell into two daughter cells. When mitosis occurs the DNA is copied, making double the amount of chromosomes in the parents cell which will late be divided into two separate cells when the cell pinches in the middle.
The cold water is the densest in the salt water ecosystem the fish that like the cold water will benefit from it.
What happens on Jane's elbow?
when a skin is scratched, the internal medium of the body enter directly in contact with the external environment, this could lead bacteria (saprophytic bacteria which lives on the skin, or bacteria from another source) it will provoke an inflammatory reaction to these pathogens and so, a pus will be formed (generally composed by dead neutrophils and purulent bacteria).
What happened on Sarah's knee?
The knee was just bruised, there's not skin scratching, it is still intact, so bacteria cannot go into the body through this injury. It just takes colors (red, blue, then yellow due to the rupture of capillaries which release blood, then will be degraded in bilirubin)
