Answer:
sympathetic nervous system
Explanation:
The sympathetic nervous system is part of the autonomous nervous system which controls the involuntary body functions as heart rate, breath rate, perspiration etc. The sympathetic nervous system is specifically responsible for the increase in the function of body functions when the body perceives a threat. When faced with a threat or distress, the sympathetic nervous system initiates physiological reactions known as the “fight or flight” response, thereby increasing the body’s alertness to such threat. Examples of increased body functions or “fight or flight response” include increased perspiration and increased heart rate, as exhibited by Blair.
Answer:
D. lower yields of fruit crops, due to decreased pollination
Explanation:
Pesticides are used to kill or stop the growth of insects that are harmful for crops but use of pesticides reduces biodiversity by killing a wide variety of insects.
Insects are one of the important component participate in the process of pollination that increases the biodiversity. insects move from one flower to other flower and spread pollen for reproduction. Due to pesticides some of the insects important for pollination got killed and reduces the pollination process. If pollination process will decrease, it will impact lower rate of reproduction of fruit crop.
Hence, the correct option is "D. lower yields of fruit crops, due to decreased pollination".
