Answer:

b. volcanoes, mid-oceanic ridges

Explanation:

Convergent boundaries occur where lithospheric plates collide head-on, with consequences that depended on the differences in plate density. Generally the highest density plate plunges under the other, partially fuses in depth and generates large volumes of magma and lava, such as, for example, on the peaceful margin of South America, between the Nazca and South American plates.  It is from this kind of boundary that volcanoes arise.

At the divergent boundaries, two plates move away from each other and the space produced by this spacing is filled by a new magmatic crust material. Thus, the divergent boundary is constructive, since it allows the expansion of the ocean floor, originating meso-oceanic chains and consequent formation of a new lithosphere.

Use mitochondrion in a sentence
olga nikolaevna [1]
Mitochondrion a singular word for mitochondria is a "powerhouse" organelle of the cell.

<span>Mitochondrion is an important organelle in most living organisms because it is where biochemical processes of living organisms such as respiration takes place. The mitochondrion has a smooth outer membrane but a larger inner membrane. The inner membrane is about 70% protein and is very convoluted because that can even fit inside the outer membrane. Mitochondrion is the carrier of the Kreb's cycle in the matrix and it is responsible for the transfer of electron chain found in the cristae of the inner membrane.</span>

Serga [27]

People are often able to live in a coma for several years because parts of the body that are not under conscious control continue to function. This situation best reflects the importance of the

A) central nervous system

B) autonomic nervous system

C) somatic nervous system

D) forebrain

Answer:

B) autonomic nervous system

Explanation:

The autonomic nervous system is a part of the peripheral nervous system. It comes under the motor division of the peripheral nervous system. The function of this division of the nervous system is to deliver the motor information from the central nervous system to the smooth muscle, cardiac muscle, and glands.  The responses produced by these muscles and glands are not controlled by the will or conscious of the individuals.  

Due to the functioning of the autonomic nervous system, the person under the coma could perform the activities such as breathing, pumping of heart to deliver the oxygen to the body cells, etc. and stay live.
