Answer:
ventricles contract and movement of blood is towards the body in systolic blood pressure and ventricles relax and movement of blood is towards heart in distolic blood pressure.
Explanation:
Blood pressure is the pressure exerted by blood on the walls of blood vessels. The standard blood pressure in human adults is 120/80.
During Systolic blood pressure, the heart <em>ventricles contract</em> and pump the blood to arteries, arterioles, capilaries then venules and veins from an area of higher pressure to lower pressure. Simply, the heart pumps the oxygenated blood towards the body. It is the higher value (120).
The Diastolic blood pressure is lower arterial pressure (80) and produced during <em>ventricular relaxation</em>. During diastolic blood pressure, the heart refills it and thus deoxygenated blood move towards heart from body.

When a lioness is hungry, she most likely gets different interoceptive (internal) signals from different parts of her body that tell her she needs to eat as otherwise she would starve - would she not receive these signals.
Answer:
O A. No, 10.6% of the class scored above her test score
Explanation:
Using the standard normal distribution (Z score) to solve this problem. The formula is as follows:
Z = x - μ/σ
Where;
σ = standard deviation
μ = mean score
x = Edna's score
According to the information given in this question:
σ = 8
μ = 75%
x = 85%
Z = 85 - 75/8
Z = 10/8
Z = 1.25
Using the table of normal distribution probabilities, we check for Z score of 1.2 under 5 = 0.8944
This means that Edna's percentage score is 89.44%. Hence, (100 - 89.44) = 10.56% is above Edna's score in the class
Approximately, 10.6% of the class scored above Edna's test score, meaning that she is not among the top 10% of her class.
