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.

fgiga [73]

Hi!


The correct option would be A. There's lower biodiversity among birds


Biodiversity refers to the variety of organisms (species) that inhabit a particular place, such as in our case different species of birds.

From the graph we can see that over time, the bird species are declining. From roughly 1700 bird species, the number has fallen to about 200 bird species by the middle of the fourth year.

Hence, we can deduce, and it would be accurate to say, that there is a relatively lower biodiversity amongst the birds with regard to that in the beginning.

Option B is incorrect because if the birds had a higher reproductive rate, they would be able to make up for the loss of bird species from the habitat. From the graph, we can assume that there's a moderately low reproductive rate among the birds.

Option C is incorrect because we do not know the affect of this pollution on the producers (photosynthesizing plant lifeforms). It may be possible that they might be declining, but we cannot conclude that solely from the graph.


Hope this helps!
