Simple epithelia have more layers for protection, whereas stratified epithelia allow materials to move across them and are less
xeze [42]

Answer: False.

Explanation:

Epithelial tissue is found in the linings of many structures throughout the body. There are two kinds of epithelial tissue: simple and stratified. And they  perform different functions and are structured differently.

The simple epithelium consists of one single layer of cells. In this way, all cells are in direct contact with the basement membrane and are separated from the connective tissue. The main function of this epithelium is <u>absorption and filtration.</u>

The stratified epithelium is composed of many layers of cells that are stacked together. In this way, this epithelium has the function of <u>protecting against physical and chemical damage.</u>

its either The division cycle of most eukaryotic cells is divided into four discrete phases: M, G1, S, and G2. M phase (mitosis) is usually followed by cytokinesis.

The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important. hope this helped!!

MrMuchimi
<span>Antidiuretic hormone (ADH) is primarily regulated by the changes in plasma osmolarity. Any alteration in the plasma osmolarity is sensed by the osmoreceptors, which are the neurons present in the hypothalamus. They then, stimulate the secretion of ADH.</span>
