Answer:
The correct answer is: positive feedback.
Explanation:
Positive and negative feedback are terms that are used to define the way a system is regulated by its products. For example, when the production of a certain substance <u>inhibits</u> its producer that is called <u>negative feedback</u>. On the other hand, when a substance <u>stimulates</u> its producer to keep secreting said substance, this is called <u>positive feedback</u>.
Estrogen is a hormone of great importance in the female reproductive cycle and is secreted by the follicle cells in response to the presence of FSH (follicle-stimulating hormone), released by the anterior pituitary when stimulated by the GnRH (gonadotropin-releasing hormone).
Estrogen appears at the beginning of the cycle to stimulate the development of the ovarian follicles, and the hormone levels continue to rise as the cycle advances. Up until the 14th day of the cycle, estrogen has a negative feedback on GnRH and FSH, but then it makes an abrupt change to now exert positive feedback on GnRH to stimulate the release of LH (luteinizing hormone), which will be responsible for ovulation.
The forearm of birds, reptiles, and humans illustrates a homologous body structure.
- Similar physical characteristics found in species with a shared origin are known as homologous structures, although these characteristics have entirely different biological purposes.
- The limbs of humans, cats, whales, and bats are examples of homologous structures.
- All of these structures—arm, leg, flipper, and wing—are supported by the same type of bone structure.
- The arms of a person and the wings of a bat are excellent examples of homologous structures. Because both bats and people are mammals, they have a common ancestor.
- Even though they appear considerably different from one another from the outside, a bat's wing and a human arm have remarkably comparable internal bone structures.
- Wings help bats fly, whereas arms enable human interaction with their environment. The wing and the arm also have various purposes.

Answer:
The correct answer is - in the ribosomes.
Explanation:
The translation is the process that takes place in the ribosomes attached to the endoplasmic reticulum where they decode the codons present in the form of the mRNA to the amino acid chain with the help of tRNA.
Ribosomes are called the factory of the protein. It involves triplet code to translate into the amino acid sequences to produce polypeptide chains or protein.
Thus, the correct answer is - in the ribosomes.
