Answer:
The correct answer is option A) "0.0 mM sucrose".
Explanation:
Since single-celled Paramecium use their contractile vacuole to osmoregulate upon hypotonic environments, it is expected that a condition where no sucrose or salt is added is the condition where the contractile vacuole would be most active. In this extremely hypotonic condition cells tend to absorb high quantities of water, the contractile vacuole pumps water out of the cell to regulate its osmotic pressure.
C i am guessing but i hope this helps
the solubility of oxygen decreases as temperature increases.
so basically warmer water has less dissolved oxygen.
i used to be in biosite my sophomore year and we would answer these questions all the time.

Answer:
There is no short answer.
Explanation:
According to the research done on the denisovan bones found in the siberia cave, the interbreeding between denisovans and homo sapiens might have took place around 44,000 years ago. The research shows what percentage of the genome of the people are similar to the denisovans and where these percentages change.
Melanesians share around 4 to 6 percent of Denisovan genome and this number goes down to around 0.2 percent among Asians and Native Americans.
I hope this answer helps.
