Answer:
D. They allow the plant to synthesize glucose under hot conditions.
Explanation:
C4 and CAM photosynthesis strategies allow for plants to produce glucose in hot and dry conditions.
Plants such as cacti, which live in hot conditions, have the advantage from their C4 and CAM systems.
In contrast to C3 photosynthesis, C4 and CAM systems allow plants to get more CO2 from the air and help them conserve water.
This then allows them to efficiently create glucose with the CO2.
So, the correct answer is D.
Answer: Correct options B, D and E.
Explanation:
In the cladogram, we can see that in the first branch we have a division, one branch goes to fish and the other goes to a division (a division means a common ancestor)
Then the fish are the most primitive (being directly related to the first ancestor)., E is true.
We also can see that between fish and birds we have 3 separations (the ancestor in common is 3 "generations" behind), and between frog and birds we have two separations (the common ancestor is 2 "generations" behind), so frogs are more closely related to birds than fish.
So D is also true.
We also can see that the only pair that has only one ancestor in common are birds and reptiles, so the ones that are most closely related are birds and reptiles. B is also true,
There is no virus that currently exists that would be considered the zombie virus. However rabies is an exceptionally close one, so comparisons can be drawn. The zombie virus would most likely require a host to remain alive so allot he important functions such as the ones that allow breathing or cardiac activity will have to remain. However the virus would most likely attack the areas of the brain mostly in regards to the areas controlling judgement, perception, anger, impulse control, and appetite.
