Answer:

Repolarization

Explanation:

Complete repolarization is achieved by the sodium pump. This actively pumps all the Na+ ti the outside and all the K+ to the inside. The pump requires energy in the form of ATP and is inhibited by metabolic poisons. Entry of Na+ is immediately followed by an increase in the permeability of the membrane to K+. These diffuse rapidly to the outside due to the concentration gradient. Being positively charged, the K+ reverses the polarity of the membrane making the outside positive.

Why might radar installations present a hazard to human health? Give two examples.
serious [3.7K]

Answer:

The correct answer is "two examples of how radar installations might cause hazard to human health are: decreased ability to perform mental tasks and induction of eye cataracts".

Explanation:

According to the World Health Organization electromagnetic fields below 10 Gigahertz of power do not represent a threat to human health, which make most radar installations safe for operation. However, some studies performed in primates by the exposure of increasing levels of electromagnetic fields have shown that they can developed a decreased ability to perform mental tasks and induction of eye cataracts. This is explained by the exposure of electromagnetic fields that can increase the animals' body temperature by one centigrade.
