Transitional fossils help scientists bridge gaps in the tree of life, resulting in a picture of gradual evolution over millions of years.
In parasitism, one organism harms another organism (the host). An example would be fleas living in cats/dogs; they feed on their blood.
Therefore the answer is A is harmed, and B is helped.
During mitosis a cell divides itself creating an identical twin cell
Answer:
The protein would be incorrect and the protein might not function.
Explanation:
We know that introns carry information but introns not only carry information to build a protein. They have to be removed for the mRNA to encode a protein with the right protein sequence.
If the spliceosome fails to remove an intron, an mRNA with extra "junk" will be created in it. As a result, a wrong protein will be created during translation.
If a wrong protein sequence is created, it will hamper the whole translation process. The protein won't function properly.
The answer is a the first one.
