The process of biological evolution often allows humans to survive consistent environmental stresses that occur across multiple generations. as humans colonized earth's diverse environments, they encountered hot, dry areas and decided to settle. what trait likely offered an advantage in this environment?

a) the ability to squint eyes to block out bright light
b) the ability to dig deep holes to find groundwater
c) the ability to shiver to create body heat
d) the ability to produce sweat to cool their bodies

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
