Answer:
3. sexual selection
Explanation:
Because artificial selection is the one made by humans like dog breeds.
Disruptive selection is when extreme values for a trait in a population are favored like big and small sizes. Stabilizing is when the trait is pushed towards the average. Sexual selection is when the trait aids in competition among individuals for access to preferred mates.
The answer is 46 chromosomes.
Before mitosis, cell duplicates its DNA material so there are 46 chromosomes in duplicates and in total there are 46 x 2 = 92 sister chromatids. During mitosis, sister chromatids first join in the middle of the cell and then separate towards the opposite sides of the cell. After they separate, there are 46 sister chromatids on the one side and 46 sister chromatids on the other side. Each sister chromatid at the end of cytokinesis actually represents the chromosome of the newly formed daughter cell.
Noooo not at all that's just bad for the environment
The answer is A because the subject is responding to something that is going on outside of it, if that makes any sense :)
Hope this helps! Have a great day!
Answer: Option A) Parathyroid glands
Explanation:
The Parathyroid gland located in the neck region helps in the secretion of an hormone called Parathormone.
This hormone helps to raise the levels of calcium ions in the body, by preventing the loss of calcium ions through urine, and also preventing excess deposit of calcium ions in the bone, thus regulating bone density.
