Sister chromatids have different alleles although carry same genes on same loci. So if it doesn't happen so, like if there are same alleles on sister chromatids then there is a problem in its formation. i.e., male and female alleles haven't contributed equally ( may be an error during their segregation process ). And obviously it doesn't happen in a real cell so we must understand this point. Because normally whenever it happens there's one half from the male and one half from the female. (i.e. maternal and paternal alleles contribute equally).
I hope you get the answer!!!
The thick loess deposits in South Dakota, Nebraska, and Iowa come from the glacial sediments from the last ice age glacial period.
Answer: D) Chemical Reaction A will have a higher reaction rate because its container has more thermal energy. This thermal energy will cause an increase in the motion and collisions of the reactants' particles.
More heat = more reaction
Explanation: took the test got it right.
