An interaction of systems allows for the body to warm itself when it is cold. Which processes help the body warm up when it is cold? Select three options. shivering sweating hair on body laying flat goosebumps forming hair on body standing up

shivering

hair on the body standing up

goosebump forming

Explanation:

The processes that help the body warm-up from the available options include the shivering of the body, formation of goosebumps on the skin, and the standing up of hairs on the body.

When the temperature of the body falls below the setpoint or the environment is cold, a homeostatic response is triggered and a signal is sent from the control center to the muscles of the body. The muscles start shaking in order to generate heat to raise the temperature of the body. At the same time, the tiny muscles at the base of the hairs on the skin contract and pull the hairs erect, causing goosebumps in the process.

answer: i would say b.

explanation:

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42
