Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
The answer is A. 0.54.
In a population p+q=1 (we have 2 alleles only).
The question states that 0.21 of the population(21%) have short legs meaning they are q^2.
So q=rad0.21=0.4582.
And p=1-q=0.5417.
Motor coretex is essential for receiving information that you are moving your legs.
<h3>What is motor cortex?</h3>
- The motor cortex's main job is to provide signals that control how the body moves. It is anterior to the central sulcus and a portion of the frontal lobe.
- The primary motor cortex, premotor cortex, and supplementary motor area make up this region.
- The motor cortex generates signals that are particular to movements and sends them to the muscles via spinal cord circuits and motoneurons to regulate motor behavior.
- For the execution of movements to be precise, coordinated muscle activation patterns are required.

It affects the layers of the earth the ozone layer which protects us from the sun can't protect very good. Which increases the tempature here on earth.
