The answer is; Mercalli intensity scale
It measures the intensity of an earthquake which can be determined by its destruction effect. The Ritcher scale on the other hand mostly measures the energy of an earthquake. The Mercalli scale ranges from I (no destruction) to XII (Total destruction).
<span>Similarly to cells, viruses can spread and grow, as well as mutate. They can change what they do becoming even more deadly or they can become immune to medicine. They can also spread from cell to cell, then from people to people, change the way they spread as they mutate, and many many other things that are usually bad for humans.</span>
The answer is biomagnification. <span>Bioaccumulation</span> involves <span>the
build-up</span> of a pollutant from the environment to an organism in a food
chain. Biomagnification refers to the tendency of pollutants to concentrate as
they move from one trophic level to the next. The substances become
increasingly concentrated in tissues or internal organs as they move up the
chain.
Answer:
The correct answer will be option-A
Explanation:
The centrifugation of the blood shows that 45% of the blood is composed of the cellular content and 55% blood plasma or liquid.
Erythrocytes or red blood cell constitute for about 41% of the total blood cells which transports the oxygen by binding it to the haemoglobin. The presence of haemoglobin is the reason the cell appears red which cause the color of the blood to appear red.
The remainder of the cell is white blood cells or leukocytes which play important role in providing the defence mechanism against the pathogen.
Thus, option-A is the correct answer.
