Answer:
The bird will nest by the light because he knows there will be food there.
Explanation:
Knowledge of genetics did not yet exist in Darwin's time, so genetic theory has since been used to explain natural selection. In addition, Darwin believed that evolution progressed at a slow, steady rate. However, that idea has been replaced by the punctuated equilibrium model, in which major changes in brief spurts.
(Mark this as the brainliest answer if this helps!)
Somesthetic Senses
There are three somesthetic senses, the skin, kinesthetic and vestibular senses. The skin is the organ that serves as protection against water loss and infectin. It transmits information like touch, pressure and temperature as it is collected by sensory receptors.
kinesthetic sense- these tells about how our body is positioned or proprioception. This transmit information based on the joint movement and how muscles are relaxed or contracted.
Vestibular Sense- the sense of balance. The main organs are the otolith and the semicircular canals in the ear.
1- The following are the examples of mechanisms which help maintain homeostasis:
- Increase heart rate in response to exercise.
- Insulin secretion in response to high blood sugar.
- Antibodies binding to virus.
2- Correct order is as follows:
- Body temperature exceeds 98.6 degrees F
- nerve cells send message from skin to the brain
- temperatures regulation center in the brain sends out signals
- sweat glands throughout the body activate to cool off skin surface
- body returned to normal temperature around 98.6 degrees F
3- Low blood sugar would likely a stimulus that would cause the body to initiate feedback mechanisms. Because If blood glucose gets too low, the body releases glucagon, which causes the release of glucose from some of the body’s cells. And this is an example of feedback mechanism.
