Because there is insufficient evidence to support the idea that all chimpanzees use tools. the scientist would need lots of hard evidence supporting this conclusion (lots of chimpanzees using tools)
Answer:
The correct statements are options C, E and F.
Explanation:
The SDS-PAGE refers to a broadly utilized technique for distinguishing proteins. The SDS or the sodium dodecyl sulfate refers to an ionic detergent. The SDS-protein complexes possess negative charge with identical charge to mass ratio such that when the proteins are run on the gel they are distinguished on the basis of their size.
As the SDS entices a negative charge to the proteins, the migration of the proteins takes place towards the positive electrode. The migration of protein takes place on the basis of the size. Thus, smaller proteins seem to migrate quickly via the gel in comparison to the bigger proteins. The binding of the protein takes place with about 1.4 times its mass of SDS resulting in the formation of a large overall negative charge.
<span>Paula, because she has performed the operation very often and now she possesses the ability to perform the operation more strategically and flexibly. Also because she has 35 years of experience should reduce such other negative factors such as complications during procedure.</span>
Answer:
At least 17 PCR cycles or 16 PCR cycles
Explanation:
As we know -
In one chain of heating and cooling of polymerase chain reaction (PCR), the strands of DNA gets doubled.
The general mathematical representation of this is
where "n" is the number of PCR cycles.
It is given that DNA strands to be produced is 16 times the original quantity of DNA.
So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less than 16 times the original quantity of DNA
