Carbon content or layer of potassium like sediments is the type of material has to be present in a rock to use radioactive dating.
<u>Explanation:</u>
- Radioactive dating is known to be the process in which the age of fossil fuels and other materials with the help of carbon content in it.
- Mostly potassium, uranium, and carbon are used for this type of process. It is a type of process in which the organic material age is determined which are younger about 50 thousand years.
- Now as a recent trend there exist a dating method called potassium-argon dating method in which the age of the rocks is found especially.
Answer:
Homeostasis
Explanation:
Homeostasis is a mechanism of the body which involves negative feedback loops that helps the body to maintain a stable internal environment when there is an external or internal change.
An example of homeostasis in the human body is the regulation of the internal temperature of the body. When there is a change in the normal body temperature, for example, if your temperature drops sharply below 37 degrees Celsius, homeostasis kicks off in the body to maintain the normal body temperature. Homeostasis uses thermoregulation mechanism which triggers shivering to raise the body temperature in an attempt to return it back to normal.
Homeostasis also makes it possible for the body to maintain the balance of water and other substances in the body like calcium in our body. For example, when the calcium level drops below normal level, the parathyroid gland secretes hormone which helps in the increasing of blood calcium levels.
Homeostasis s a essential mechanism that helps keeps the body in a balance and functional state.
