Answer:
The correct answer will be option-C
Explanation:
Oxygen consumption is the amount of oxygen used by all the cells and tissues during cellular respiration.
The oxygen consumption is a measure of the metabolic reactions taking place in the cell. The increased consumption of oxygen indicates that the high production of ATP is required to maintain the internal temperature.
In the given question, since the consumption of oxygen is higher in crickets at 25° C than mice at 10 °C indicates that rate of cellular respiration process has increased to maintain the internal temperature as a mechanism of the Homeostasis.
Thus, Option-C is the correct answer.
Explanation:
Chromosomes contain nucleus that make up DND, RNA, and protein ( histone)
The answer is because when the heart pumps blood in the artery during systole it counteracts the resistance provided by the blood vessels. This requires high pressure that is provided by the force of ejection due to the contraction of the ventricles. On the other hand, the pressure is lowest during diastole which is the ventricular filling of blood. There is low resistance in the blood vessels and the arterial wall pressure declines until the heart starts to contracts again.
