Answer:

The answer to the question, would be: during fatigue.

Explanation:

Normally, a muscle fiber will respond to neurological stimulation to perform movement. In this case, the whole process of movement of the fiber results from the biochemical processes that lead the muscle to respond to calcium and use ATP, so that the chain reactions can be carried out, and the fibers can move. However, there is a point at which, ATP is depleted, and there is an overproduction of lactic acid, which prevents muscle fibers from further responding to stimulation from the motor neuron, regardless of the amount of ACh released to bind with the sarcomeres´ receptors. At this point, then, the muscle fibers are incapable of further responding to stimultation, and thus movement is stopped.

The process shown here is called ____. The resulting offspring, Dolly, would be genetically identical to the ____. This is becau

Mama L [17]

Answer:

cloning, Finn-Dorset, DNA, nucleus

Explanation:

So basically what they're doing here is they're taking the cytoplasm of a cell of the Scottish Blackface sheep (maybe a lamb?, whatever)/removing the nucleus inside that cell and instead inserting the nucleus of the Finn-Dorset sheep. Then they insert that "integrated" cell (so to speak) into a surrogate ewe so that the blastocyst can evolve and develop into Dolly (the lamb/sheep).

The process is cloning. The resulting offspring would be genetically identical to the Finn-Dorset (sheep/lamb) b/c the nucleus is coming from that sheep & the nucleus has the genetic material (DNA). Hope ya found this helpful :)

P.S. Oh yeah, and thanks for the fifty points (hopefully)

What three types of evidence allows us to determine whether organisms shared a common ancestor?

Anika [276]

The evidence of common ancestry is based on study of three parameters; fossils record, homologies of various organisms, and study of biogeography. Fossils record determines the similarity and differences of bones as well as shells of different organisms over a given period of time. On the other hand, studying of homologies involves assessment of mitochondrial DNA and other proteins with an aim of finding similarity from one organism to another. Finally, Biogeography is the assessment of how continental drift might have separated organisms which had got common ancestry and they were living together.
