Explanation:
adaptation sounds like having longer legs
lizards that had longer legs had more access to food
so
they had more chances to mate

Answer:
the division of cytoplasm is unequal in oogenesis, whereas it is equal in spermatogenesis
Explanation:
Spermatogenesis includes meiosis in primary spermatocytes. These are the diploid cells and completion of meiosis in one primary spermatocyte forms four haploid spermatids. The process of cytokinesis at the end of meiosis-I and meiosis-II equally divides cytoplasm among the daughter cells. Therefore, all the cells produced have an equal amount of cytoplasm.
On the other hand, oogenesis includes unequal cytokinesis by the end of meiosis-I and meiosis-II. It produces a larger secondary oocyte and a relatively smaller first polar body by the end of meiosis-I. Similarly, the mature egg cell is also larger than the second polar body. This occurs so that the zygote can have enough cytoplasm to enter mitosis.
I think the correct answer among the choices listed above is option B. For photoperiodism to occur, a plant must use a phytochrome. This is a pigment that plants use to detect light. It is sensitive to light in the red region. Hope this answers the question.
