Dna and rna differ in all but one of the following ways.
a)
dna is double-stranded, while rna is single stranded.
b)
rna uses the sugar ribose in its backbone, while dna uses deoxyribose.
c)
dna contains the base uracil, while rna contains the base thymine instead.
d)
dna is found in chromosomes in the nucleus, while rna can move around the cell.

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.

Ascientist observes certain changes in the physical features of a particular species over time. she concludes that the species has undergone evolutionary change. she wants to study the animals by analyzing their population. she’ll use . the population of this species is decreasing considerably. if this trend doesn’t change, this species will fall under the category of animals. this is a plato question,i need to make up his biology credit.
