<u>ANSWER</u><u>:</u>
<h2><u>DEFINITIONS</u></h2><h2>_____________________________________</h2><h3><u>VOLUNTARY MUSCLES:</u></h3>
Voluntary muscles are those muscles which work under our conscious control and can be controlled at will also we can choose choose them when to use and when not to use. These are simply SKELETAL MUSCLES attached to the bone, so all the movements of hand and legs and whatever u do are because of voluntary muscles.
<h3><u>__________________________________________________</u></h3><h3><u>INVOLUNTARY MUSCLES:</u></h3>
the muscles in the human body that do not work under our will and we cant control them. They are mainly controlled by the autonomic nervous system in the body. So, involuntary muscles include all the muscles whose activity which is not controlled by our NERVES. They are also called SMOOTH MUSCLES since they are present as the visceral layer over the organs.
<h2>_____________________________________</h2><h2>DIFFERENCES</h2>
1) VOLUNTARY MUSCLES are under our control but INVOLUNTARY MUSCLES are not under our control
2) VOLUNTARY MUSCLES are also known as skeletal muscles but INVOLUNTARY MUSCLES are also known as smooth muscles
3) VOLUNTARY MUSCLES are attached to the bones in the body, but INVOLUNTARY MUSCLES are attached to the soft hollow internal organs.
4) VOLUNTARY MUSCLES are controlled by the somatic nervous system. INVOLUNTARY MUSCLES are controlled by the autonomic nervous system.
5) VOLUNTARY MSUCLES require more energy. INVOLUNTARY MUSCLES require less energy.

HOPE THIS HELPS!</h2><h2 />
The water vascular system of a sea star enables movement, digestion and respiration through the use of water to exert force on limbs known as tube feet. The vascular system is primarily water but also contains coelomocytes, protein and potassium salts.
The answer is letter a. loop
Answer:
The correct answer would be adaptive radiation.
It is a natural phenomenon by which ancestor species diversify into new forms as a result of adaptation towards changing the environment, limited or different resources, new challenges or new ecological niches.
For example, Darwin's finches faced new niches, different environment, different types of food resources due to which they adapt to different species bearing beaks of different shapes and sizes.
<span>It is acting as a local signaling agent. It allows for more platelets to be attracted to the damaged area, instead of having them sent all over the body. As a local signal, it is also acting on the behavior of nearby cells, which is seen by the vascular spasm that is being instigated at the site of the damage.</span>
