For the purposes of this question, assume that a g1 somatic cell nucleus in a female myrmecia pilosula contains 2 picograms of d

Using the theories of the cells, we got that 4 picograms of DNA would be expected in a metaphase in cell of a female if we assume that a g1 somatic cell nucleus in a female myrmecia pilosula contains 2 picograms of DNA.

Mitosis and meiosis are both types of the cell division. Mitosis is the process by which the most cells in the body divide, involves a single round of cell division, and produces the two identical, diploid daughter cells. Meiosis is the process by which the gametes are produced.

DNA synthesis is the primarily common to both. If already formed, the cardiac tissues and nervous system cells will never replicate their daughter/sister cells either through the meiosis or the mitosis.

Hence, if we assume that a g1 somatic cell nucleus in a female myrmecia pilosula contains 2 picograms of DNA, then the amount of would be expected in a metaphase i cell of a female is 4 picograms.

What would happen if you did not have the stapedius and tensor tympani muscles? A. The ear canal would stay permanently closed.

<h2>(D) is the correct option </h2>

Explanation:

Both the stapedius and tensor tympani are striated muscles
The stapedius is about 6 mm in length, arises from the pyramidal process and the tendon attaches to the posterior neck of the stapes
The stapedius is a muscle with a high oxidative capacity
The tensor tympani is about 25 mm in length, the muscle is not as strong as the stapedius, and the tendon also contains more elastic tissue and fat
The tensor tympani courses through a bony canal in the wall of the anterior middle ear, and attaches to the neck of the manubrium
The tensor tympani and stapedius muscles are protective reflexes
They reduce the amount of sound that gets into the inner ear
They are somewhat similar to the blink reflex thus they can be triggered by loud noise, and when they go off, both ears can be involved
If stapedius and tensor tympani muscles is not present then loud sounds would cause the ossicles to move too much, potentially causing damage to the inner ear
