Do you think ancient Antarctica was situated in a different location from its location today? Why or why not?

I do think Ancient Antarctica was situated in a different location from it's locations today because of continental drift, this is caused by the moving of the tectonic plates by the mantle which is under the Earth's crust due to the cooling and heating of magma (or lava, cant remember). this causes the plates to collide with each other, go in opposite ways or "swallow" one another (basically one plate goes under the other causing the one under to melt and reappear where two other plates are separating)

The toxic cyanide anion (CN-) binds to cytochrome c oxidase and prevents electron transfer. Dosing of BP-CML cells with cyanide

astra-53 [7]

Answer: C. Ii & III are correct

II. reduced intracellular ATP.

III. apoptosis or necrosis.

Explanation:

Cytochrome c oxidase controls the last step of food oxidation. Cytochrome c oxidase is an enzyme responsible for electron transfer in the electron transport chain (ETC), it inhibit in slowing down or stopping the ETC.

Consequently, ATP production would be gradually reduced, as the ETC is responsible for the majority of ATP production. This shows option II is correct.

The question starts by stating that cyanide is highly toxic, so this match up with the fact that a large dose would also cause cell death (apoptosis or necrosis). Therefore, option III is also accurate.

Option I: Inhibiting the ETC is consequential as it reduces oxygen demand because electrons would not flow to oxygen, the final electron acceptor.

Base your answer on the graph below and on your knowledge of biology. The graph shows

andrey2020 [161]

Hello. The chart mentioned in the question above is attached just below.

Answer:

A) has increased with increasing human population

Explanation:

As you can see in the graph below, the line that indicates the number of endangered species increases as the line that represents the increase in the human population increases. This means that the number of extinct species has increased with the increase in the human population.

This is because with the increase in the human population, there is a growing need for natural resources, in addition to increasing the need for cities to expand. All of this results in greater deforestation and extraction of natural resources, which ends up causing an increase in the factors responsible for the extinction of animals.
