Which of these describes one way that the human nervous system maintains a constant body temperature when the external temperature is cold?
A. The Nervous system increases perspiration
B. The nervous system causes digestion to speed up
C. The nervous system causes bloods vessels to construct
D.The nervous system triggers the flight-or-flight response
Answer:
A
Explanation:
Nerves trigger sweat glands to release fluid that evaporates and cools the skin. Conversely, a drop in core temperature makes blood vessels constrict to conserve heat. The nervous system also triggers muscles to shiver to generate heat and warm the body.Apr 15, 2018
The nervous system causes blood vessels to constrict. Therefore, option (C) is correct.
What is nervous system?When the external temperature is cold, the human nervous system works to maintain a constant body temperature through a process called thermoregulation. One way this is achieved is by causing blood vessels near the skin to constrict, reducing blood flow to the skin and helping to retain heat within the body's core. This response is known as vasoconstriction.
Vasoconstriction is controlled by the sympathetic nervous system, which is part of the autonomic nervous system. This system is responsible for controlling involuntary bodily functions, including heart rate, blood pressure, and body temperature. When the body's core temperature drops, the sympathetic nervous system activates and causes the blood vessels to constrict, helping to maintain a constant internal temperature.
Increasing perspiration (A) can help to cool the body down in hot conditions, but it is not a mechanism for maintaining body temperature in cold conditions. Digestion speeding up (B) and the flight-or-flight response (D) are not directly related to temperature regulation.

reputoring of arteries is dangerous why
Answer:
If an aneurysm grows too large, it can burst open, or rupture, and lead to dangerous bleeding inside the body. Aneurysms can also cause a split within the layers of an artery wall. This split, called a dissection, can lead to bleeding within the artery's layers. Aneurysms that rupture or dissect can cause sudden death.

Flowers are a reproductive structure for some plants. The corpse flower blooms for a short period of time, and it smells like a mixture of rotten food, decaying organisms, and garbage. This repulsive scent attracts pollinating insects to the flower.
Do you think the corpse flower’s smell meets the definition of an adaptation as stated in the video? Explain your response.?
Answer:
Yes. Because the flower blooms for only a short time, it needs to attract pollinators quickly so that it can reproduce. If it didn’t have this adaptation, the plant might not be able to produce offspring.
