Many chemotherapy drugs used to treat cancer work by modifying the mitotic spindle. Paclitaxel works by interfering with normal

Minchanka [31]

Answer:

by inhibiting the mitotic spindle plasticity

Explanation:

In eukaryotic cells, the mitotic spindle is the cytoskeletal structure by which sister chromatids are separated during cell division. Spindle microtubules are known to drive chromosome segregation, while tubulins are Microtubule-Associated Proteins (MAPs) that attach to microtubules in order to modulate their dynamics. Antimitotic drugs are nowadays widely used in chemotherapy to disrupt microtubule assembly and chromosome segregation, thereby producing mitotic arrest and cell death (apoptosis).

If hunting continues and drastically reduces the deer population, how might this impact the hawk population?

laiz [17]

Well, considering if the deer and the hawk have a direct predator prey relationship, where the deer are the prey, then the hawk population will also drop quite a lot, unless they have some other major food sources, but chances are they'll still drop.

If it's NOT a direct predator prey situation, for example: The deer happen to eat something that the hawks also eat, or the deer are prey for something the hawks eat:
If the deer eat something the hawks eat, by them dropping it means there will be more food supply for the hawks, meaning as the deer population drops, the hawk population will go up.

If the deer are PREY to something the hawk eats, then by there being less deer, then whatever the primary consumer of the deer is will also drop. If the hawk eats that predator, then there will be less of those predators, and less prey, meaning the hawk population will still drop

You were most likely given a food web to look at. Seeing how you didn't post that, I just gave you the only 3 situations that could happen.

Answer:

1- was a proponent of evolutionary change.

2- established a binomial system of classification for plants and animals

Explanation:

Carolus Linnaeus was a Sweden naturalist that is considered to be the creator of the modern taxonomy. He created a dichotomic system to classify species, in which species are fixed entities without phenotypic modifications across time, this concept being contrary to Darwin's ideas. Linnaeus published his nomenclature botanical system in the book "Species Plantarum", which is nowadays a reference book for plant nomenclature.

Which of the following statements describes a central role that ATP plays in cellular metabolism?

DaniilM [7]

Answer: The correct answer is D. ATP provides energy coupling between exergonic and endergonic reactions.

ATP hydrolysis is an exergonic reaction, as a large amount of energy is released when this molecule is hydrolyzed. ATP is converted into ADP ( adenosine diphosphate) and inorganic phosphate. The energy released in this reaction is utilized by the endergonic reactions ( which require energy) such as photosynthesis.

Thus, the central role that ATP in cellular metabolism is that it provides energy coupling between exergonic and endergonic reactions.
