After fertilization, the successful development of a mature, full-term fetus depends on A. The release of human chorionic gonadotropin (hCG) by the developing placenta AND the production of estrogen and progesterone by the placental tissues B. the release of human chorionic gonadotropin (hCG) by the developing placenta C. maintenance of the corpus luteum for all 9 months D. all of these E. the production of estrogen and progesterone by the placental tissues

Answers

Answer:

The correct option is A (The release of human chorionic gonadotropin (hCG) by the developing placenta AND the production of estrogen and progesterone by the placental tissues).

Explanation:

The developing placenta release Human chorionic gonadotropin (hCG) during pregnancy. What this hormone does is tell the body (corpus luteum) to produce progesterone to maintain the pregnancy. The presence of Human chorionic gonadotropin is a sign of pregnancy, meaning successful fertilization had happened, and implantation of the embryo had occurred too, preventing another cycle of menstruation.

The successful development of a mature, full-term fetus also depends on estrogen which during pregnancy aids the formation of blood vessels and also aids fetal maturation. While progesterone is a hormone when released during pregnancy helps maintain a healthy pregnancy.

What happens if the sequence is changed (mutations)?

Answers

Explanation:

A mutation may change a trait in a way that may even be helpful, such as enabling an organism to better adapt to its environment. The simplest mutation is a point mutation. This occurs when one nucleotide base is substituted for another in a DNA sequence. The change can cause the wrong amino acid to be produced.

(d) A conservation group with a long-term goal of preserving species believes that all at-risk species will disappear whenever land inhabited by those species is developed. It has an opportunity to purchase land in an area about to be developed. The group has a choice of creating one large nature preserve with an area of 45 square kilometers and containing 70 at-risk species, or 5 small nature preserves, each with an area of 3 square kilometers and each containing 16 at-risk species unique to that preserve. Which choice would you recommend and why

Answers

Answer:

each with an area of 3 square kilometers and each containing 16 at-risk species unique to that preserve

Explanation:

I choose third choice of having each with an area of 3 square kilometers and each containing 16 at-risk species unique to that preserve because allocation of separate preserve provides good space and less competition in that preserve. Less number of at risk species in a large surrounding area increase in population with higher rate due to availability of resources such as habitat, food and water in large amount as well as low competitors for these resources.
