Regulatory functions such as feedback loops are very common in nature and happen thousands of times every day within our bodies alone.
A feedback loop is one of the methods by which biological organisms regulate functions. Feedback loops are a self-regulatory means through which the output of a system is then used as the input. Feedback loops can be of two types:
Positive FeedbackNegative FeedbackA positive feedback loop is one in which the system is stimulated to increase the production of a product. For example, the low levels of an enzyme in the blood will cause the body to produce more of that enzyme in a positive feedback loop. A negative feedback loop is just the opposite, in which high levels will cause a decrease in production.
Feedback loops are a vital part of maintaining homeostasis and for the survival of all organisms. Therefore, we can conclude that option D is correct in stating that feedback loops are common in nature and make the system stable.

ProtistsProtists are eukaryotic organisms that can respire either through aerobic respiration ( the use of oxygen ) mostly for obligate protists. while certain parasitic protist can respire through anaerobic respiration process ( without the use of oxygen ).
Protists can be Fungi, animal or even plants therefore from the options given above most protists can respire with and without oxygen.

what organelle is made of two layers of phospholipids
Answer:
The plasma membrane
Explanation:
Mannitol salt agar (MSA) only allows the growth of halophiles. Among the halophiles, mannitol fermenters release acid that turns the pH indicator yellow; mannitol nonfermenters leave the medium red. Onto MSA you inoculate a halophilic mannitol fermenter, a nonhalophilic mannitol fermenter, and a halophilic mannitol nonfermenter. Thus, the medium is acting as a __________ medium.
Mannitol salt agar can act as both a selective and differentiating medium. A selective medium is one in which inhibits the growth of a particular organism, and allows others to thrive in said conditions. In this case, MSA favors halophilic organisms. MSA is also a differentiating medium because of the mannitol content. Mannitol is a sugar and mannitol fermenters, like s. saprophyticus, use mannitol and release acid as a byproduct. The pH indicator within the agar changes from red to yellow.
