Answer:
The structures that prevent the atrioventricular valves from reopening into the atria are called chordae tendineae (option a).
Explanation:
Tendinous cords, or chordae tendineae, are structures in the form of fibrous filaments that connect the atrioventricular valves to the papillary muscles of the ventricles.
The function of the chordae tendineae is to prevent the mitral and tricuspid valves from opening during ventricular contraction, preventing backflow of blood from the ventricles to the atria.
The chordae tendineae are predominantly made up of collagen and elastin, in addition to a small percentage of endothelium.
The other options are not correct because:
b. Myocardial septa is the division between the right and left ventricles.
c. Purkinje fibers are fibers that transmit the nerve impulse that allows ventricular contraction.
d. Semilunar cusps, correspond to the shape of the closed semilunar valves.
Pour 67 mL of juice followed by 29 mL of juice into a 100mL graduated cylinder what's the percent strength
Question Completion:
Pour 67 mL of Juice B followed by 29 mL of Juice A into the 100 mL graduated cylinder. What is the percent strength of each juice?
Answer:
The
percent strength of Juice B = 70%.
The percent strength of Juice A = 30%.
Explanation:
a) Data and Explanation:
Juice B = 67 mL
Juice A = 29 mL
Graduated Cylinder capacity = 100 mL
Total juice of B and A = 96 mL
The percent strength of Juice B = 70% (67/96)
The percent strength of Juice A = 30% (29/96)
b) The percent strength is the computation of how much of Juice A substance is dissolved into a specific amount of Juice B liquid. The percent strength establishes the part-to-whole relationships. A percent is a part of the 100 total parts. The 100 total parts in this case = 96 (67 + 29). Therefore, the part of Juice A in the total parts = 29/96 * 100 = 30% , while the part of Juice B in the total parts = 67/96 * 100 = 70%. Knowing the percent strength of each liquid helps to determine the content of each juice.

British colonists living in America and the British Government in Great Britain. What were they fighting over
Answer:
The british colonists in America were fighting for Self government and independence.
Explanation:
The colonists were not happy with the colonial government (British government) because they could not govern themselves. This brought about a series of events that led to the American Revolution of 1775 to 83'. The American colonists were paying much in taxes to the king and yet they felt they had no representative to this government in the parliament, despite the taxes they paid. The king tried to suppress the American colonists by the use of military force and violence. This led to tensions that finally escalated into war between both sides.

Which of the following statements is FALSE about alcohol?
Blood alcohol concentration slowly increases as it is absorbed from the stomach and the small intestine.
Appears in the blood a few minutes after it has been consumed
BAC levels are identical for all individuals who drink the same amount in a given time
Alcohol concentration slowly decreases until level returns to a zero.
Answer:
BAC levels are identical for all individuals who drink the same amount in a given time
BAC levels are identical for all individuals who drink the same amount in a given time. So, the correct option is (C).
What are BAC level?BAC stands for Blood Alcohol Content. It is also called blood alcohol concentration. It is described as a measure of the intoxication of an alcohol used for legal or medical purposes. It is expressed as mass per volume of alcohol or mass of blood.
Alcohol is the major intoxicant found in many intoxicated drinks. When we drink a beverage that contains alcohol, the stomach and small intestine rapidly absorb the alcohol and mix it into the bloodstream. Alcohol is toxic to the body, so when the liver metabolizes alcohol to filter it from the blood.
Levels can range from 0% (no alcohol) to over 0.4% (a potentially fatal level) which are not identical for all individuals who drink the same amount in a given time.
Thus, BAC levels are identical for all individuals who drink the same amount in a given time. So, the correct option is (C).
