You get into an argument with your classmate about whether ATP hydrolysis is required for actin polymerization. You argue that A
Ray Of Light [21]

Answer:

It is a very good discussion debate, although I believe that the most effective way to generate the actin head to generate such a displacement requires a good full energy currency, which is considered much better by ATP.

Regarding the information sought in 1950 (Straub), he was publishing that he could bind ATP and that during the polymerization of the protein to form microfilaments, it hydrolyzed to ADP + Pi, which remained bound to the microfilament.

Straub suggested that this reaction played a role in muscle contraction, but this is only true for smooth muscle and was not verified experimentally until 2001.

At the point where it is stated that ADP + Pi is necessary for the formation of polymers, it is extremely true and a very good posture.

What we can highlight as false in all this argument is that for muscle contraction ATP is not needed, since for it to occur if or if there must be ATP or energy currency.

Explanation:

Then we can conclude that both statements are valid with the difference that in the case of ADP + Pi it requires more evidence.

Due today i have a C and need to bring my grade to a B and will mark brainliest
Ostrovityanka [42]

Answer:

-What types of toxins were found in the waters of the Lower Passaic Superfund site?

DDT and agent orange were found in the waters of the Lower Passaic Superfund site.

-How were some fish able to survive PCB levels thousands of times higher than sensitive fish can withstand?

in some tolerant fish, the trigger for the changes that can be caused by PCB levels are can be turned off which allows some fish to survive levels of PCB thousands of times higher than the levels affecting sensitive fish.

-What is the advantage of a large population for rapid evolution?

The advantage of rapid evolution is that the animals can survive and not get killed off.

-Do you think all species would be able to evolve adaptations to help them survive pollutants? Why or why not?

I don't think that all fish can get speedy evolutions like the killfish did because researchers think that they got a rare mutation which helped them survive. However as researchers say, in smaller populations with less diversity the chances that a rare mutation might happen is small.

-What will likely happen to these toxin-adapted fish if the waters are eventually cleaned up?

Once the water becomes clean, a tolerant fish with the mutation won't do as well as a sensitive fish would do.

Explanation:

Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day! Thank you : )
