I don't seem to see any where to drag
Answer:
The correct answer is D.
Explanation:
Papillary muscles, attached via chordae tendineae, help to close the valves and prevent regurgitation.
Pectinate muscles are parallel ridges in the walls of the atrium of the heart, mainly in right atrium. They can stretch during adverse loading conditions, to <em>help the right atrium to dilate without much wall stres</em>s.
Answer:
Pulmonary circulation
Explanation:
is the movement of blood from the heart to the lungs for oxygenation, then back to the heart again. Oxygen-depleted blood from the body leaves the systemic circulation when it enters the right atrium through the superior and inferior venae cavae.
Jeremy is going with dehydration and electrolyte imbalance which commonly thought to be the cause of muscle cramps. This is most evident factor when training in hot and humid conditions due to an increased loss of electrolytes through sweat.
Exercise associated muscle cramps are mainly treated with hydration and electrolyte supplementation but this could be neglecting the underlying cause of cramps during or after exercise. The most effective way of treating cramps before they affect body athletic performance is neuromuscular re-education.
What is neuromuscular re-education?
Neuromuscular re-education involves training weak, underactive muscles to help balance the work load..
Charle horse is type of a cramp which occurs when the muscle involuntarily contracts and cannot relax. The calves and thighs are two of the most common areas affected, although cramps can strike hands, arms, abdomen, and feet.

Answer:
Only the extracts from heat-killed cells treated with RNase are unable to transform nonvirulent bacteria into virulent bacteria.
Explanation:
The experiment by Avery, McCarty and MacLeod aimed to identify Griffith's "transforming principle," which is a principle that explains how transformation is a way of recombining, exchanging, or transferring genetic information between organisms or from one organism to another. For this, they used cell that were heat inactivated and purified the transforming principle of these cells.
The purified cells did not give positive results in the tests done by the scientists, but they presented transformants very similar to the DNA. However, Avery suspected that the result should be reinterpreted and that the molecule was not a DNA. This is because RNA degrading enzymes had no effect on the transforming principle and only RNase-treated heat-killed cell extracts are unable to transform non-virulent bacteria into virulent bacteria.
