Answer:

B) Valves closing

Explanation:

A healthy heart makes a lub-dub sound with each beat. This sound comes from the valves shutting on the blood inside the heart. The first sound (the lub) happens when the mitral and tricuspid valves close.

How can doing something for someone else help to relieve stress?
sp2606 [1]
<span>The answer is letter C.<span>

<span>In doing something for someone else, your mind gets off of its own troubles. Helping someone could serve as a diversion from stresses that you experience. In doing this, you are immersing yourself in an environment where stressors are not present. Aside from this, the experience makes you feel socialized and well accompanied by the presence of another, where you can share and talk about other things other than your problems. Socializing is one of the best ways to distress from monotonous activities and is highly encouraged by experts to be done on a regular basis.</span></span></span>
