Based on each person's statements, identify which of the following you AGREE with, and then explain your reasoning. Courtney: “It is obvious that everything that eats plants would die but all the other organisms on the island would be okay.” Jose: “Courtney I think the organisms that eat plants would just learn to eat other things. So initially they might decline in numbers but eventually, their numbers would increase back to their current amount.”Raquan: “I have to disagree with both of you. I think that all of the organisms on the island would die, because at some point even the mammals who don’t eat plants directly would ultimately discover that what they usually ate has already died.” Mike: “I kind of agree with Courtney, except I don’t think that all of the things that eat plants will die. I think the things that eat both plants and animals would live and only those that can’t or won’t eat animals will die.” Keisha: “Mike is right. I would add that since there are fewer things for the larger mammals to eat that we would ultimately see fewer of them on the island.” Alex: “I argue that organisms that eat plants would learn to swim so they can eat the seaweed and algae in the water.”Plzz explain your reasoning!!

Select ALL of the following that are directly used to control fatty acid oxidation in cells.A. negative feedback regulation if free fatty acids accumulate
B. changing the activity of the acylcarnitine shuttle
C. targeting the acetyl-CoA transport shuttle in the mitochondrial membrane
D. altering the activity of the oxidoreductase enzymes in β-oxidation

Answers

Answer:

The correct statements are A negative feed back regulation if free fatty acid accumulate C targeting the acetyl CoA transport shuttle in the mitochondrial membrane

Explanation:

The beta oxidation of fatty acid can be regulated by several following ways.

A The accumulation of free fatty acids exerts negative feedback during beta oxidation of fatty acids.As oxidation of fatty acids result in the breakdown of complex fatty acids in free fatty acids and acetyl CoA,the accumulation of free fatty acids lowers the rate of beta oxidation of fatty acid.

C The targeting of end  product of beta oxidation that is acetyl CoA to the mitochondrial membrane also regulates the beta oxidation pathway.Because more the transport of acetyl CoA to the mitochondrial membrane more will be the rate of fatty acid break down by beta oxidation.

During summer in the Northern Hemisphere,A.
the Sun rises earlier and sets later than during other seasons.
B.
the Sun appears lower in the sky than during other seasons.
C.
there are fewer hours of visible sunlight each day than during other seasons.
D.
the Sun rises in the Southeast and sets in the Southwest.

Answers

Answer:

A

Explanation: In the summertime in the northern hemisphere, the Earth is farther from the Sun because of the ellipse in its orbit, but the angle of the Earth's tilt points the hemisphere towards the Sun, making the days longer. The Sun's angle is also higher during the summer months than the winter months.

PLS HELP I’m not sure which one it is lol

Answers

Answer:

Option B)

Explanation:

A moon is a celestial body that revolves around a planet.

The others are wrong because, a planet orbits around the sun, not the sun orbiting the planet.

A meteor does not have a fixed orbit, and asteroids orbit around the star near it, in our case, the asteroid belt orbits the sun.
