Answer:
Explanation:
b. Based on the graph, the molar concentration is -0.32 M.
c. When water moves from areas with high water potential to areas with low, the phloem cells accumulate sugars. This results in transpiration.
Geographic isolation leads to allopatric speciation
Explanation:
-One species could split into two if a physical barrier (such as a new river, divided its geographic range)
- If the barrier is large enough, gene flow between them would cease and the two separate populations would evolve independently.
- Different alleles would be fixed in them; because of the hazards of mutation and drift, or because selection favored different characters in the two.
- Then if the barrier is removed and the populations are reunited, they might remain distinct from each other.
- There would now be two species where there was formerly one.
Answer:
You always use the base pairing rule. When pairing RNA to DNA, use complementary base pairs. Just always be sure to use uracil in the RNA instead of thymine.
