Answer:
Biotic: Plants
Abotic: Rocks
Explanation:
A biotic factor is something in an ecosystem or environment that is living. Some examples that could be found in a park are grass, flowers, trees, squirrels, pigeons, fish or people.
An abiotic factor is the exact opposite of a biotic factor: something in an ecosystem or environment that is not alive. Some examples that may be found in a city park include a park bench, a trash can, rocks, a playground, a pool, basketball court, temperature, and humidity.
The answer is; cell surface receptors that are recognized as antigens by the recipient's immune system.
Therefore the organ is attacked as a foreign substance . This is why organ transplants are given by the closest family member to reduce the antigen variability that causes transplant rejection. Tissue typing is done to ensure that the organ or tissue is as similar as possible to the tissues of the recipient.
Answer:
An increase in the amount of greenhouse gases in the atmosphere
Liquid; gas
Lacking oxygen
To decrease the temperature in the compost pile
Explanation:
1. Methane is one of the greenhouse gases. When these gases are released into the atmosphere, they increase the temperature of the earth surface because they trap heat within the earth. Other examples are carbon dioxide and water vapor.
2. Evaporation is a phase change from liquid to gas. During this process, heat is supplied to a liquid. When the molecules of the liquid gain enough energy, they then begin to break off into gaseous form. The reverse process of evaporation is condensation.
3. Anaerobic is a process that lacks oxygen. Aerobic processes are carried out with the availability of oxygen.
4. The reason why compost should be regularly mixed is to decrease the temperature in the compost pile. Portions of the compost can have a higher temperature than other parts. Therefore, mixing the compost will help to redistribute the heat in the compost.
At this point in time, we have yet to reach the carrying capacity for humans. So yes there is a carrying capacity for humans we just haven't reach it yet.
