D. Explain the relationship between the pulse recorded in the finger and heart muscle contraction E. Which components of the cardiac cycle (atrial systole and diastole, ventricular systole and diastole) are discernible in the pulse tracing?

D. Heart contraction and pulse are connected with one another.

E. Atrial diastole and ventricle diastole.

Explanation:

Heart construction and pulse of an individual are connected as one can hear the pulse every time contraction of the heart is completed. Pulse can be understood by this that it represents the number of the contractions is completed by heart each time.

In the pulse tracing, there are two parts of the heart that are discernible which represents the contraction of the heart that are Atrial diastole and ventricle diastole.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
