Explanation:
After mitosis, two identical cells are produced with the same original number of chromosomes of the parent's cell. In this case, if a cell has 24 chromosomes, each daughter cell will have 24 chromosomes after mitosis
Answer:
many anterior pituitary hormones regulate other endocrine glands whereas posterior pituitary hormones regulate nonendocrine tissues
Explanation:
Anterior pituitary or adenohypophysis is the anterior lobe of the pituitary gland. Secretion of endocrine cells of the anterior pituitary is controlled by regulatory hormones released by hypothalamus. The hypothalamic releasing hormones bind to anterior pituitary endocrine cells, upregulating or downregulating their release of hormones. Anterior pituitary hormones stimulate endocrine glands: FSH and LH (ovaries and testes), TSH (thyroid), and ACTH (adrenal cortex).
Posterior pituitary or neurohypophysis is the posterior lobe of the pituitary gland. It is not glandular it is just a collection of axonal projections from the hypothalamus. Posterior pituitary hormones regulate nonendocrine tissues: ADH-vasopressin (kidney tubules) and oxytocin (mammary glands, uterine tissues, brain).
DDT has adverse affect on our environment due to its presence for a long time.
<h3>What is DDT?</h3>
DDT is an insecticide that can pass up in the food chain i.e. from insects to small birds, and then from small birds to big birds like hawks. High concentrations of DDT in birds leads to weakness in the egg shells.
This leads to a decrease in their population so we can conclude that DDT has adverse affect on our environment due to its presence for a long time.

Answer:
Similarities in embryos are evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. Most vertebrates, except for fish, lose their gill slits by adulthood.

itz from gologolo lol I hope it helps uh
keep smiling #smilies
The answer is:
<span>Step 1 Genetic material duplicates.
</span>Step 2 Cell grows in size and other <span>organelles duplicate.
</span><span>Step 3 Cell wall or membrane forms.
</span>Step 4 Cells separate.
Binary fission is a type of cell division characteristic for prokaryotic cells. In this process, after the cell reaches its maximum size, the genetic material starts to duplicate. These two copies of genetic material are now connected to plasma membrane. The cell begins to grow in size and thus separate those two copies of genetic material. Other organelles are duplicated, too. Next, a new cell wall or cell membrane starts to grow in the middle of the cell leading to the separation of the cell.
