Answer:
Explanation:
There are many options, here are a few choices:
Fast moving water tends to be colder than slow water; some of it originates as snow melt on the sides of mountains, for example. For this, animals in fast water tend to be more cold resistant. This is why you do not see fish like freshwater trout in equatorial regions. These animals struggle and die in slow, warm water.
Fast moving water means that if the animal or plant wants to stay put, it must resist the flow. Fish tend to be far more muscular and lean in these places, while insects like stoneflies, mayflies, and other larvae have ways to secure themselves to rocks and plants while growing. Plants develop strong root systems, and algae hold fast in rocky crevices in the river. Some animals also have suction in order to stay in place where there is fast flowing water.
Some animals have to adapt their reproductive systems as well. Because finding a mate is difficult in the sweeping waters, breeding tends to happen all at one time. As an example, salmon have runs, where thousands of fish all swim upriver at once to breed, can dramatically alter the surrounding ecology of the river. Insects like mayflies have hatches, where hundreds of thousands of flies swarm into the air at once to breed and lay eggs.
b) 36%
c) 66%
d) 58%
e) 24%
Answer:
Option C, 66%
Explanation:
Zoonotic pathogens are the ones which are transmitted from animals to human beings.
As per the study of world health organisation, nearly 61% of human diseases caused by pathogens are due to Zoonotic pathogens. This percentage has increased from last ten decades to 75%.
As per Center for Disease Control and prevention, more than 50% pathogens are Zoonotic pathogens
These pathogens can enter human being through various medium such as air, water, contaminated food, hand or mouth contact etc.
Some common examples of disease caused by zoonotic pathogens are -
Malaria, dengu, Typhoid etc.

Answer:
B
Explanation:
The rocks' forms and edges are smooth and appear to have been rounded. This is a hallmark of abrasion because the rocks lose their sharp edges and round out as a result of the constant rubbing and scraping action of wind-borne particles against them.
