Answer:
According to me answer no 4 is correct.
Explanation:
single cell amoebas can perform all life functions capture the food, digestion, respiration, excretion, and reproduction also. These all are similar to multicellular animals.
Answer:
<u>b. first thoracic</u>
Explanation:
Sympathetic nervous system is<u> one of the divisions of the autonomic nervous system</u>. The other divisions are <u>parasympathetic nervous system</u> and <u>enteric nervous system</u>.
Autonomic nervous system is composed of <u>preganglionic neurons</u> and <u>postganglionic neurons.</u>
Similarly, the sympathetic nervous system is composed of postganglionic and preganglionic neurons.
The cell bodies of<u> preganglionic neurons of sympathetic nervous system is found in intermediolateral cell columns of spinal cord segments T-T12 and L1-2 or 3</u>. Therefore, sympathetic nervous system is also called <u>thoracolumbar division.</u>
The cell bodies of parasympathetic nervous system are found in the <u>brainstem nuclei which exit via cranial nerves 3, 7, 9, 10 and also in the sacral spinal cord segements S2-4</u>, therefore parasympathetic nervous system is also known as <u>craniosacral division.</u>
<u>QUESTION:</u>
<u>b. first thoracic</u>
<u>This is the correct answer choice as sympathetic nervous system cell bodies are found in intermediolateral cell column of T1-12 and L1-2 or 3 spinal cord segments. Hence, a sympathetic nerve is most likely to leave via first thoracic vertebra.</u>
<u>Third lumbar is less likely as sympathetic nervous system does not extend to this level in every individual.</u>

Answer:
There was no receptor for epinephrine to associate with and invigorate the sign transduction course that prompts the actuation of the compound
By and large, Earl Sutherland helped in translating and discovering the breakdown of the glycogen into glucose-1-phosphate in nearness of glycogen phosphorylase and this sign course pathway is activated by the epinephrine. The epinephrine doesn't have the correct receptor to discover and start the sign transduction process and thus glucose-1-phoshate isn't shaped. It requires CAMP which is again a second delivery person for starting the entire of the transduction procedure.
Bacteria are the simplest single cells that carry out all basic life activities.
Hope this helps!
Have a great day! :D
