The chestnut lamprey is a jawless native fish that can attach its mouth to the side of another fish, such as a lake trout. The lamprey releases a substance that prevents the lake trout's blood from clotting and uses its tongue to create suction that draws a steady flow of blood and body fluids from the lake trout. This type of lamprey rarely kills the lake trout before detaching and moving on. The relationship between a chestnut lamprey and a lake trout can best be described as – commensalism

mutualism

predation

parasitism

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.

idk im sorry.
