Many poisonous mushrooms are extremely colorful. One hypothesis is that the colors serve as a warning to prevent animals from eating the mushrooms, much like the bright yellow and black stripes on wasps help to deter potential predators. Why do mushrooms need to deter predators when the majority of a mushroom consists of the underground mycelium?

Many poisonous mushrooms have bright colors that serve as the warning signal to animals that the mushroom is poisonous and by eating it they can die.  

Mushroom is a fungus and most of its part is consists of underground mycelium. The part of the mushroom which is above the ground is the fruiting body of mushroom and is umbrella-like. It is called cap in which gills underside of the cap. These gills contain spores that are disperse and produce more mushrooms.

Therefore as the cap is fruiting body and contains spore so to protect the spores mushroom need to deter predators.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
