The cardiac output may be calculated as the product of heart rate and stroke volume. Thus, the cardiac output in this situation is 9.9L/min.
<h3>What is Stroke volume?</h3>
Stroke volume may be characterized as the volume of blood output with each beat of the heart which is 110 ml/beat in this question.
Cardiac output = Heart rate × Stroke volume.
90 × 110ml/min = 9,900ml/min = 9.9L/min.
Therefore, the cardiac output in this situation is 9.9L/min.

<span>Surfactant, which is a mixture of fatty lipids and proteins are secreted by alveolar type II cells that line the perimeter of the inside of our empty alveolar space and aids in the movement of air and liquids that go in and out of the lungs. These cells may line other vital organs to protect it against outside wear and tear and keep the tissue inside our bodies intact making bodily functions working more smoothly.</span>
Answer:
The sample treated with RNase
Explanation:
According to this question, a novel virus was found which was capable of killing mice when injected into them and capable of making a nonvirulent virus to be virulent by transforming them.
After heat killing the novel virus, different samples were treated with either an RNase, a DNase, or a Proteinase. If the novel virus uses double-stranded RNA as its genetic material, the sample treated with RNase will no longer be capable of transforming the non-virulent strain. This is because RNase is a catalytic enzyme that degrades RNA, hence, the RNA will no longer be present to transform.
The important lesson learned is that the study of ecology can be fundamental in a management program.
<h3>What is ecology management?</h3>
The expression 'ecology management' makes reference to the strategies aimed at enhancing the ecological features of a geographic area.
Ecology management is a fundamental issue to achieve sustainable ecology development.
In conclusion, the important lesson learned is that the study of ecology can be fundamental in a management program.
