Answer:
The respiratory system as well as circulatory system (hormonal system) are involved in controlling the negative feedback of our body.
Explanation:
The respiratory system helps in controlling the negative feedback in such a way that if CO2 level increases in body the system acts in such a way so as to decrease its level in body . the system attains a normal level by increasing the blood circulation and increasing the breathing level forcing CO2 outside of our body.
in case of circulatory system, the blood has several hormones released from glands . the most common example is Insulin and Glucagon .
if a person is hypoglycemic then glucagon concentration increases and blood glucose concentration returns to normal and if a person has hyperglycemia then insulin level increases which in turn increases glucose uptake from body and body returns to normal level.
Solution:
It is the system of earth with orbiting satellites, transmitting signals continuously towards the earth,which enable the position of receiving device on near the earth's surface to be accurately estimated from the difference in arrival times.
The Earth system has always changed. But right now it has an additional pressure forcing change: human activites. This force is now global and dominant. The response of the Earth system to this pressure is an important area of science. Which are as follows:
• Oceans
• Land
• Cryosphere
• Life
This is the required right answer.
If i am not mistaken , the answer is
- enzymes are not changed by facilitating a reaction
-enzymes lower the activation energy of a reaction
-enzymes are specialized proteins.
i am sorry if my answers were wrong .
