What is the primary type of biological anthropology scenario b biological anthropologists have observed several chimpanzees in western africa making tools to them hunt. the chimpanzees were seen modifying branches and sticks into spears. they removed any leaves or small branches to make a smooth shaft. they also chewed on the end of the branches to give them sharp points. they then thrust the sharpened branches like spears into tree trunks, where small primates called galagos make sleeping nests. although it remains unclear how successful the chimpanzees are in actually killing galagos, multiple members of the chimpanzee group have been observed producing the spears. in this research?

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.

not sure if this is what you'r looking for eubacteria and archaebacteria

i think the answer is a.keratin is the pigment responsible for skin color.
