Answer:
The adaptation in owl butterfly helps it to camouflage and also protects it from predators. Adaptations allow organisms to be better suited to their environment. So the answer is both 'A' and 'B' .
Explanation:
Owl butterfly use the concept of mimicry. It is a form of <em>adaptation</em> in which they fool the predator in thinking that they are owls and not butterflies. These butterflies have eyespots under their wings. By flashing them they look like the <em>eyes </em>of an owl.
Since owls feed on small animals, and small animals feed on butterflies, the owl butterflies protect themselves from predators. The small animals thinking that the butterfly is an owl, run away instead of coming closer. This way these small insects camouflage and protect themselves.
The answer is definitely cactus, which is B. I say this because the cactus plant does not require much water to grow. It also folds it's leaves into thorns to avoid transpiration (releasing water). Hope i helped. Have a nice day.
Answer:
spermatogenesis
Explanation:
The stem cell that is located inside the seminifeous tubules inside the testis of a male, with a high level of testosterone, start the maturation process that last 74 days.
First the stem cell derived into the spermatogonia, the inmature cell that enters into a mitosis division to multiply the cells with a full number of chromosomes.
Later they enter into a meiosis process in which the spermatogonia turn into primary spermatocyte, then into a second spermatocyte, until being a spermatid. After this process the spermatids have the half of the number of chromosomes.
The last step is to maturate the spermatids into sperm cells with all the cell structures and nutrients.
