It might be c because lipids are essential because if carrying fats

The right answer is D

These are essential constituents:

• membranes of the body's cells (neurons, enterocytes): to preserve their viscoelasticity thus optimized cellular exchanges

• the nervous system (brain and nerves)

• the neurotransmitter acetylcholine

• bile fluid (micelle formation) synthesized by the liver and stored in the gallbladder

These polar lipids having a hydrophilic part which affords them an affinity with the aqueous medium, and a lipophilic part which allows them an affinity with fatty acids which do not have affinities with aqueous media allow the solubilization of apolar triglycerides in lipophobic aqueous media (the intestine is an aqueous medium)

The glycerol and phosphate portion of the molecule is said to be hydrophilic (which likes water) while the fatty acids are hydrophobic (which does not like water). The hydrophilic part is soluble in water while the hydrophobic part is not (it is soluble in lipids).

The glycerol-phosphate portion is hydrophilic whereas the fatty acids are hydrophobic. The phospholipids are often represented by a ball, the hydrophilic portion, and two "legs", the hydrophobic fatty acids.

Placed in water, the phospholipid molecules tend to form a monomolecular layer (a molecule of thickness) where only the hydrophilic portions are in contact with water.

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
