Answer:B
Explanation:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
The best explanation for the greater rate of transport for solute A than for solute B at higher solute concentrations is that there are more frequent collisions of molecules of A than that of B.
<h3>How does concentration affect transport of molecules</h3>
- Concentration is the amount of solute dissolved in a given volume of solution.
Given two solutions A and B of different concentrations, The solution of higher concentration will have a higher amount of dissolved solutes.
Given A has a higher concentration, the solutes will collide with themselves much more than in B.
Hence, the molecules of A will tend to move faster than that of B.
Therefore, the best explanation for the greater rate of transport for solute A than for solute B at higher solute concentrations is that there are more frequent collisions of molecules of A than that of B.

Answer:
d) peduncular hallucinosis
Explanation:
One of the most striking symptoms of perpendicular hallucinosis is the existence of very vivid, colorful, and recurrent visual hallucinations. These hallucinations occur due to lesions of the brainstem and thalamus, which can influence a disinhibition of the lateral geniculate nucleus. The hallucinations provoked can be very debilitating for the person suffering from this illness and can completely disassociate him from reality.
Species that are not closely related and that do not share many anatomical similarities can still be placed together on the same phylogenetic tree by comparing their "homologous genes that are highly conserved".
<u>Explanation:</u>
A phylogenetic trees refer a representation describing evolutionary connections between species, these trees are not conclusive evidence nor theories. In a phylogenetic tree the sequence of splitting illustrates how species or other groups developed from a set of common ancestors.
A gene transmitted by a common ancestor in two species is considered to be "a homologous gene". Although it may be equivalent in series, related sequences aren't homologous necessarily. Orthologous are homologous genes, where a gene detracts after an occurrence of speciation, but preserves the gene and its crucial role.
I’m guessing it’s c, although I’m not a 100% sure, I do feel like this is the best answer.
Hope it helps!
