Which is more hydrophilic, phospholipids or cholesterol? explain

Pgospholipids

Explanation:

Cholesterol is a highly apolar molecule. It has an OH that forms the polar head, which gives it a minimum of water solubility but is also too low to be considered a hydrophilic molecule.

Phospholipids have four main parts: a phosphate group, linked to long or short-chain alcohol, and two fatty acids that form the tails.

Fatty acids are not polar but both alcohol and phosphate groups are, which makes it a semi-permeable molecule.

In comparison, we can say that phospholipids are more hydrophilic molecules than cholesterol.

i'm pretty sure it's spores

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
