Answer:
The correct answer is A. The cell membrane is both hydrophilic and hydrophobic due to the presence of phospholipid.
Explanation:
98% of the lipids present in cell membranes are amphipathic, that is, they have a hydrophilic end (which has affinity and interacts with water) and a hydrophobic end (which repels water). The three main types of lipids in eukaryotic membranes are phospholipids, sphingoglucolipids and steroids (especially cholesterol); It is worth mentioning that phosphoglycerides and sphingolipids are found in all cells. The latter, glycolipids and steroids, do not exist or are scarce in the plasma membranes of prokaryotic cells, fungi and some protists. There are also neutral fats, which are non-amphipathic lipids, but only represent 2% of the total membrane lipids.

<h3>What is a Tooth?</h3>
Many animals have hard, calcified structures called teeth that are situated in their jaws or mouths and are used to chew down food. Some animals, especially carnivores and omnivores, also use their teeth for defensive purposes, to scare other animals—often including their own—to catch or injure prey, rip food, or carry prey or their young.
Gum tissue covers the tooth roots. The ectoderm, the embryonic germ layer, is the source of a variety of tissues with various densities and hardness that make up teeth instead of bone.

Answer:
of a stimulus of some sort
Explanation:
In psychology, the stimulus-response theory is used to indicate that the behavior is a consequence of the interplay between a stimulus and its corresponding response. The behaviorism states that a stimulus will produce a corresponding reaction (response) either by pairing it with a reflective trigger or by rewarding it with a response (i.e., when the stimulus is present). This current of thinking focuses on the modification in observable behaviors as a result of the learning process.
