In general, the process responsible for the growth and repair of human tissue is the healing process, which takes place in three phases.
1. inflammatory response. Injured tissues release chemicals that draw resources to the area, alert the body that damage has occurred and inhibit function to prevent further injury.
2. Repair phase. Once injured area is walled off and debris removed, construction to replace or repair injured tissue begins. New blood vessels grow in the injured area maximizing transport within tissue.
3. Remodeling phase. Construction of permanent tissue , typically strong scar tissue made from dense network of collagen fibers.
Looking at it from cell level, the process of mitosis is actually taking place during healing.
Mitosis is used for growth and repair and produces diploid cells identical to each other and to the parent cell.
New cells are needed throughout life. These are for growth and replacement of damaged or worn out tissue. The body obtains such through the process of mitosis.
The nitrogen cycle could no exist without bactria. bacteria that lived inside the ground, catch the nitrogen that has been fixed and covert it into nitrate.
They'll have to do the following 2 stpes:
- Look for evidence that suports their conclusion
- Do tests in order to prove their hypothesis

The answer is A. Environmental conditions are not always right to produce flowers and seeds for sexual reproduction.
Most plants are able to reproduce either way because even if the conditions aren't right for the plant, it can still make more flowers so it doesn't die out.
I hope this helps! :D
Answer:
There is a higher oxygen content in the air of the lungs than that of oxygen-depleted blood and a lower carbon dioxide concentration. This gradient of concentration causes gas exchange during respiration.
