Answer:
The correct answer is lateral rectus muscles.
Explanation:
To see what is happening in his side, or what originated the loud noise, Ryan has to use his lateral rectus muscle. Lateral rectus is one of the five extra ocular muscles that help in movement of the eye balls and help to see what is happening in and around us. It is mostly responsible for abduction, i.e. the movement of the eye balls away from the center line of the body. Defect in this muscle can result in sixth nerve palsy.
Answer:
Neural stem cells are normally found within the brain and spinal cord. NSCs are specialized stem cells that can differentiate into the cell types of the central nervous system, including neurons and glial cells
Explanation:
A virus<span> is a small </span>infectious agent<span> that </span>replicates<span> only inside the living </span>cells<span> of other </span>organisms<span>. Viruses can infect all types of </span>life forms<span>, from </span>animals<span> and </span>plants<span> to </span>microorganisms<span>, including </span>bacteria<span> and </span><span>archaea
</span>While not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles. These viral particles<span>, also known as </span>virions<span>, consist of two or three parts: (i) the </span>genetic material<span> made from either </span>DNA<span> or </span>RNA<span>, long </span>molecules<span> that carry genetic information; (ii) a </span>protein<span> coat, called the </span>capsid<span>, which surrounds and protects the genetic material; and in some cases (iii) an </span>envelope<span> of </span>lipids<span> that surrounds the protein coat when they are outside a cell. The shapes of these virus particles range from simple </span>helical<span> and </span>icosahedral<span> forms for some virus species to more complex structures for others. Most virus species have virions that are too small to be seen with an </span>optical microscope<span>. The average virion is about one one-hundredth the size of the average </span>bacterium<span>.</span>
