To measure the volume of the starch-water mixture in the dialysis bag, the students should have used a
(1) meterstick (3) graduated cylinder
(2) triple-beam balance (4) test tube
The answer is 3) graduated cylinder. A measuring stick to measure depth would not have worked as the overall volume of the beaker containing the </span>dialysis bag would not have changed. A test tube would generally have insufficient volume to measure the volume of the <span>dialysis bag and a test tube is generally not graduated. A triple beam balance is generally used to weigh mass and not volume. </span>
Answer:
pressure changes of alternating contraction and relaxation during the cardiac cycle.
Explanation:
Opening and closing of heart valves are regulated by changes in the blood pressure of various heart chambers during the cardiac cycle. During atrial systole, the higher blood pressure in the atria opens both AV valves and forces the blood to enter the ventricles. The semilunar valves are closed. During ventricular systole, the higher blood pressure in the ventricles opens both semilunar valves to allow the blood to enter the pulmonary trunk and aorta. At this time, both the atrioventricular valves are closed.
The major function of the large intestine is to absorb water from the remaining indigestible food matter and transmit the useless waste material from the body.
