Answer:
Direct relationship.
Explanation:
There is a direct relationship between water clarity and orca survival because the survival of orca depend on the quality of water. If the water quality is good and clean, the orca survival rate increases whereas if the water quality decreases due to pollution, the orca survival also decreases. The chemicals drained into the water bodies is the main cause of lowering orca survival rate so we can say that both have direct relationship.
Answer:
Explanation:
Thalamus passes information to and from the cerebrum
Cerebrum is responsible for higher-level thinking skills
Hypothalamus helps maintain homeostasis; regulates body temperature
Answer:
It is double stranded DNA, and it could be from an eukaryote, a prokaryote or a virus.
Explanation:
You can rule out the possibility of the nucleic acid being RNA because of the presence of thymine, which is absent in RNA, and is replaced by the base Uracil. In double stranded DNA, guanine pairs with cytosine, and thymine pairs with adenine, so the proportions of A and T, as well as those of C and G, should be the same. This is consistent with the information given, so you can conclude that it is indeed double stranded (this can also be concluded simply by the fact that it is DNA, because this type of nucleic acid is always double stranded).
All types of organisms can have a DNA genome, so it could either belong to eukaryotes, prokaryotes, or viruses. If it were RNA, it would only be possible for it to belong to a virus, since they are the only ones that can have an RNA genome.

These are the organisms that are considered to be the single celled protists most closely related to animals because the characteristics that can be found in these organisms are the characteristics that were probably present in the animal's ancestor organism. </span>
