Answer:
<u>d. Skeletal muscle</u>
Explanation:
There are two components of efferent nervous system.
- <u>Somatic nervous system</u>
- <u>Autonomic nervous system</u>
<u>SOMATIC NERVOUS SYSTEM:</u>
Somatic nervous is one of the components of efferent/motor nervous system.
It controls <u>voluntary activities</u>. It involves the <u>control of skeletal muscles</u>.
It is composed of <u>the motor neuron and the innervating muscle</u>.
<u>AUTONOMIC NERVOUS SYSTEM:</u>
Autonomic nervous system is the other efferent/motor system of the body. It controls the <u>involuntary activities</u>. It involves the control of <u>cardiac muscle, glands and smooth muscles</u> of the body.
It is composed of<u> 2 neurons; preganglionic and postganglionic neurons.</u>
Autonomic nervous system is further divided into:
- Sympathetic nervous system (it is responsible for flight and fight responses)
- Parasympathetic Nervous system (it is responsible for rest and digestion)
- Enteric division ( controls Gastrointestinal system)
<u>QUESTION:</u>
<u>d. skeletal muscle</u>
This is the correct answer choice as skeletal muscles are not controlled by autonomic nervous system. They are controlled by somatic nervous system and are under voluntary control.

Answer:
The correct answer is option A. It answers scientific questions as accurately and completely as possible.
Explanation:
The scientific method or the process is a process that helps in answering the scientific question about the natural world phenomenons and acquire knowledge. This process involves different scientific steps that follow in order to answer as accurately and completely as possible.
The scientific process involves these steps in order - observation, forming a question, making a hypothesis, experiment to test, analyze the experiment data and result, and conclusion based on analyzing.
Thus, the correct answer is - A. It answers scientific questions as accurately and completely as possible.
Answer:
<em>23%</em>
Explanation:
The maximum number of individuals of a population that a particular ecosystem can hold is known as the carrying capacity of that particular population.
As the reptiles living in the ecosystems, without the mammal species, had to compete less, hence there carrying capacity was more in such areas.
There s a difference of 23% in the carrying capacity fir reptiles in the areas where the particular species of mammals were present.
240+ 150= 390
240-150= 90
90 divided by 390 and then multiplied by 100 gives 23%.
