Answer:
Northeastern China, North Korea, South Korea, Northern Japan all have coniferous forests, temperate grasslands, agriculture and are located in a humid continental climate zone. Why is bamboo considered one of the best renewable resources on the planet? It grows quickly and in dense conditions.
The active hyperemia is the consequence of dilation of arterioles and the resultant influx of blood in the capillaries, which occurs during blushing or excercise.
<u>Explanation:</u>
The rise in organ blood circulation correlated with an organ or tissue having elevated metabolic activity is understood as active hyperemia. An illustration of active hyperemia is the rise in blood flow that follows muscle contraction, also named skeletal muscle activity or responsive hyperemia.
It typically occurs when blood is needed by the organs more than normal. Your blood vessels are expanding to improve blood running in. Reactive hyperemia is the blood circulation reaction to occlusion of blood flow, while active hyperemia is the blood flow result of increased metabolic activity of the tissue.
Answer:
b. Works within an upper and lower range
c. " Is regulatory. "
d. Is very common in biological systems
Explanation:
Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.
For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.
