8. Wind pollination required a great deal of excess pollen, just so some of it lands, by chance, in the right place. Animal pollination is more selective because animals pick pollen up and carry it directly to where it needs to be. Although there is still a chance that the pollen will be from the wrong plant species, plants can manipulate variations in animal behavior through the structures of their flowers, the time and season of flowering, or the rewards or attractive chemicals they produce to narrow the field of pollinators, and increase the chances of having exactly the right pollen put in exactly the right place.

Answer:
The correct answer is - B. Woodchucks hibernate to survive the winter.
Explanation:
Many mammals such as groundhog or also known as woodchucks hibernate during winter in order to survive winter. Hibernation is the process or state of minimal activity during a particular time of the year characterized by low body temperature, slow heart rate, and low metabolic rate.
Woodchucks are become less active and remain in their burrow and seen very little during the winter and stay like this till late winter or early spring.
Answer:
Yes
Explanation:
A high quality DNA sample will have a 260/280 ratio of around 1.8. This value means that the DNA is sufficiently pure and free from other contaminants that could affect downstream experiments and analysis.
The ratio for this sample is 0.489/0.257 = 1.9
This is close to 1.8, and therefore the sample is of sufficient quality ot use downstream.
Each carbon atom can potentially form 4 bonds, which allows it to form big and complex structures. In addition, the stability of carbon-carbon and carbon-hydrogen bonds make carbon based molecules very stable.
