The answer will be an ecosytem
Answer:
No, cardiac muscle tissue does not exhibit recruitment.
Explanation:
The cardiac muscle tissue does not recruit cells to contract. The reason is that the cardiac muscle contracts all its cells at once and with the same force. It does not have to recruit other cells since it does not have to lift objects of different weights. The heart's contraction aims to pump blood and to do it rhythmically. The heart has a natural peacemaker, the sinoatrial node. The Sinoatrial node transmits an electrical impulse to all the heart to contract it all at the same time and continuously. For these reasons, the cardiac muscle does not need recruitment.
This question is incomplete. The options are:
a. Oligocene b. Eocenec. Miocene<span>d. Pleistocene
</span>Option b is correct. This relates to the Paleocene-Eocene Thermal Maximum (PETM) which occured around 56 million years ago and was similar to modern-day climate change. Warming of more than 5 degrees Celcius occured over<span> 15-20 thousand years because of input of more than 2000 gigatons of carbon into the atmosphere. The PETM resulted in mass deep ocean extinctions and mass terrestrial and shallow ocean diversification.</span>
Answer:
Nucleus
Explanation:
It is enclosed by a nuclear membrane perforated by numerous pores. It regulates the activities of the rest of the cell. It contains chromosomes which carry the hereditary materials. One or more densely staining bodies called nucleoli is present in the nucleus. It is site for synthesis of ribosomes
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.
