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.
Yes it is necessary for the production of apt in your cells because apt needs oxygen to form correctly.
<span>The 4 categories of macromolecules include carbohydrates, proteins, lipids, and nucleic acids. Carbohydrates (grains and vegetables) are the largest group at the base of the pyramid, proteins (milk, poultry, eggs, nuts) follow up the pyramid while lipids (fats and oils) are the least amount at the summit of the pyramid. </span>

</span><span>The aim of the pyramid is to recommend ideal rations for a healthy diet. Carbohydrates provide most of the energy needs for the days’ activities hence taking the largest portion. Proteins are used in building muscles, f0r nutrition, and body’s immunity hence required in lesser amounts compared to carbohydrates. Lipids help the body store energy since they have thrice as much energy as carbohydrates.They also a constituent of cell membranes and also help deliver vitamins. They are required in the least amount to avoid obesity and related illnesses such as cardiovascular <span>diseases</span></span>
Answer:
c) Gives a cell its distinctive characteristics
Explanation:
Carbohydrates perform two main functions in the cell's membrane: <em>they participate in cell recognition and adhesion</em> (cell-cell signaling or cell-pathogen interactions), they also have a structural role as a physical barrier.
Most of the carbohydrates linked to the membrane are in the form of <em>glycoproteins oy glycolipids</em>, these are the molecules that share information and recognize host cells. <em>Glycocalyx </em>is another way we find carbohydrates in the cell membrane, this layer has cell-adhesion molecules that enable cells to adhere to each other.
I hope you find this information useful! Good luck!
Answer:
Ecology is the study of organisms and how they interact with the environment around them. ... Changes in ecosystems can result from many different factors including diseases among the organisms living in the area, increases in temperature, and increased human activities.
