The blood cells will lyse (burst) because the water is hypotonic to the cells.
Answer:
C
Explanation:
A rainforest is humid, therefore, water uptake would likely not be an issue. However, rainforests have a huge number of trees, often these are very tall. These large trees might block out the sun from the smaller plants nearer the ground. This means they would struggle to properly photosynthesise, as they wouldn't have the necessary light energy.
Therefore, as a survival adaptation, it is likely that an allele that produced broader leaves for photosynthesis would be selected for in this population. Broader leaves would give a larger surface area for the plant to absorb light energy to perform photosynthesis.
I believe it is the "myelin sheath." White matter = myelinated (has myelin sheath), while gray matter = unmyelinated (no myelin sheath)!
