Answer:

C. 275 nm

Explanation:

At 275 nm of ultraviolet wavelengths causes mutation in a skin cell because at 275 nm of wavelength, maximum DNA Copying Errors occur in the cells that leads to mutation in the cell. A mutation is a kind of change that occurs in the DNA, due to two reasons, due to mistakes that is occur when the DNA is copied or as the result of environmental factors such as ultraviolet radiations.

larisa86 [58]
The skeletal system of a human body gives form, shape, and structure of the body. These includes all the bones and all the joints with each bone being a complex organ itself. 

The skeletal system has two divisions: (1) axial and (2) appendicular. All the vertical 80 axial bones comprised the vertical axis of the body while the 128 including free appendages consist the second division.

The answer to the question above based on the description given is AXIAL.

lina2011 [118]

The organelle that provides evidence for this theory is the mitochondria and the chloroplast.

<h3>What is the endosymbiotic theory?</h3>

The endosymbiotic theory is the theory which describes how the eukaryotic cells arose from simple prokaryotic cells.

In the endosymbiotic theory states that when two prokaryotic cells with several abilities came together, one engulfed the other and existed in a symbiotic relationship that enabled  the cells to meet their needs for survival an growth.

The mitochondria and the chloroplast provides evidence for the endosymbiotic theory.

In conclusion the endosymbiotic theory describes  how eukaryotic cells arose from simple prokaryotic cells.
