<span>Answer: C) nearly 0% hydrogen </span>
Hydrogen plays a very significant part in the existence of stars around nebulae. A vast amount of hydrogen is needed for stars to be born. Hydrogen heats up and ignites due to a chain reaction from the collision of atoms but since there is no gravity acting upon the nebulae, it takes millions of years for the stars to exist.
<span><span>We can assume then that when the stars are born they contain 100% hydrogen. As they age, hydrogen is depleted. The oldest the star the least hydrogen it has. So the answer is </span><span>C) nearly 0% hydrogen </span></span>
The quadriceps muscles will contract.
Explanation:
Quardriceps are muscles of the thigh located in the front.
It is a group of four vastus muscles named as-the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris.
Muscles posses the ability of contraction so an action potential that will excite the muscle cells will obviously result in contraction of the muscles.
So we can conclude that on depolarizing the muscle cell of the quadriceps will result in contraction of quadriceps.
