Answer:
The dispersion pattern of the population depends on the type of the population and their distribution in the environment. Different types of dispersion are uniform, random and clumped.
The uniform dispersion occur when the population is evenly spaced out in the area. Random dispersion is independent of the other individuals and randomly spaced. Clumped dispersion is greatly influenced by the behavior and the resources. Population are present in small patches.
Answer:
B. increase, because the partial pressure of CO2 in the blood will decrease.
Explanation:
The presence of carbon dioxide gas in blood imparts H+ ions due to its reaction with H2O and thereby, lowers down the blood pH.
When more air reaches alveoli, the rate of gaseous exchange is increased. More of the carbon dioxide is removed from the blood and is released out of the body via exhalation.
Removal of carbon dioxide from blood would increase the pH of the blood since the partial pressure of CO2 in the blood would decrease.
Answer:
A) Surface-active agents, or surfactants, decrease surface tension among molecules of a liquid.
B) Phenolics exert antimicrobial activity by injuring lipid-containing plasma membranes, which causes the cellular components to leak out of the cell.
C) Alcohols exert their action by denaturing proteins and dissolving lipids.
Explanation:
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.
Answer: Incomplete dominance
Explanation:
In incomplete dominance, both alleles are expressed but have become blended giving rise to a new trait with one also been more noticed than the other although both are expressed. For instance a red flower and a white flower are crossed, giving rise to a pink flower. As compared to codominance, both alleles are equally expressed and are equally dominant. For example, a white college crossed with a black hen giving rise to a black and white (checkered) chick.
