Phytoplankton refers to the microscopic marine species that thrive at the bottom of the food chain. They obtain their energy from carbon dioxide via photosynthesis, like plants and thus are very essential in carbon cycling.
Phytoplankton forms the base of almost every ocean food web. Thus, it can be stated that they make the majority of other ocean life possible. They are the source of food for zooplankton and small fishes, as well as for larger animals like jellyfish and whales.
Thus, if the population of phytoplankton gets declined, it will indirectly affect other species in the aquatic ecosystem. It can also be said that with the decrease in the population of phytoplankton, the population of other major species in the ecosystem also gets a decline.
Answer:
A) reduced synthesis of ovarian steroids despite high levels of gonadotropin hormones.
Explanation:
Menopause is characterized by depletion of ovarian follicles, a reduction of ovarian hormones to castrate levels and elevated levels of serum gonadotropins. Rather than degenerating, the reproductive neuroendocrine axis in postmenopausal women is intact and responds robustly to the removal of ovarian hormones.
Menopause marks the cessation in reproductive cycles of middle-aged women. It is heralded by depletion of ovarian follicles leading to the loss of ovarian hormones with repercussions throughout the body.
The temperature at which the amylase catalyzed reaction is fastest is significant because that is the optimum temperature for the enzyme.
Amylase is an enzyme that catalyzes the digestion of enzyme. The optimum temperature of an enzyme is the temperature at which it works best. The optimum temperature of amylase is approximately 37 degree Celsius; this temperature also happen to be the normal body temperature.<span />
Raltegravir and Elvitegravir are the medications that act by binding with integrase enzyme. They prevent human immunodeficiency virus (HIV) from incorporating its genetic material into the client's cell. They belong to the group of drugs called integrase inhibitors, because they <span>lock the action of the viral enzyme that inserts the viral genome into the DNA of the host cell.</span>
