Answer:
all organisms need food for the energy required to live and grow.
Ovulation is triggered by peak concentrations of luteinising hormone peptide secreted into the blood, which is option B.
<h3>What is ovulation?</h3>
Ovulation is the release of an ovum from an ovary.
Luteinising hormone is produced by anterior part of the pituitary gland and stimulates ovulation and the development of the corpus luteum in female mammals.
The luteinizing hormone is released in by the pituitary gland of the brain, which triggers the ovulation.

d) Crabs and crayfish
The answer is C. Small birds.
On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to Island, which helped him to develop his theory of natural selection.
Answer:
The correct answer is option C.
Explanation:
PAX5 refers to the member of the Pax gene family, which is, accountable for conducting the genetic information, which will encode the Pax-6 protein. It functions as a master control gene for the maturation of eyes and other sensory organs. Pax6 functions as a regulator in the formation of patterns and coordination needed for the proliferation and differentiation to take place effectively. This ensures that the procedures of oculogenesis and neurogenesis are taking place efficiently.
The PAX6 gene was the outcome of evolution in earlier animals comprising eyespots or eyes. The similar PAX6 gene generates distinct kinds of eyes in distinct species because of the difference in its control of PAX6 expression. At the time of the evolution of vertebrates, the biological clock opsin’s rh gene was chosen as a gene for visual receptor pigments.
