Answer:
A- There is no competition for resources
Explanation:
The answer is a have a nice day
Answer:
a. No, it is not possible.
A heterozygous female carries one copy of functional gene which is enough for the production of clotting factor. Hemophilia does not show continuous variation or polygenic inheritance and thus, its level does not depend on the number of normal alleles.
It that was the case, then all males would show hemophilia in some parts of the body as they only carry one X chromosome and thus, only one functional gene.
Thus, heterozygotes are only the carriers of the disease, they do not show any symptom of the disease.
b. In perspective of homozygosity or heterozygosity, the rate of blood clotting should be the same as both of them have functional gene. As mentioned above, it does not show continuous variation so, it will not show any increased or decreased rate of clotting in homozygotes or heterozygotes.
However, in reality, the rate of clotting depends on the concentration of clotting factor present in blood plasma. This percentage depends on the physiology of a person but not on the number of alleles present. For example, proteins or enzymes required for gene expression, et cetera.
Answer: The plasma membrane (regulates the entry and exit of cell materials).
Explanation:
All living organisms are composed of one or more cells. The cell can be defined as the smallest functional unit of all living organisms. Also called the basic organizational unit of life.
Cells are found to have many features in common. However, a generalized cell does not exist. The precise structure of a cell is closely related to the work it does.
According to the structure of a cell, it has a living material called protoplasm. The protoplasm is enclosed by a membrane known as the PLASMA MEMBRANE.
The PLASMA MEMBRANE is a flexible membrane that is made up of mainly proteins and lipids. It prevents the cell contents from escaping to the exterior. It is also selectively permeable, that is, it controls the materials which are allowed to enter or leave the cell.
Other structures of a cell include:
--> Nucleus: This is the most important cell structure as it houses the genetic information of the cell.
--> The cell wall: this surrounds the plasma membrane but is freely permeable.
The secondary level of consumers will be affected trace amounts of pesticides, like DDT, that run off into lakes, streams and ponds.
<h3>What are Producers</h3>
Producers are mainly plants that undergo photosynthesis to produce carbohydrates and oxygen.
<h3>Consumers</h3>
Consumers are herbivores or canivores or omnivores that feed on primary producers like plans and others.
- Consumers can be primary which feed on plants examples are goats.
- Secondary consumer are canivores that feed on meat of other animals, they feed on primary consumer.
- Tertiary consumers feed on both plants and meat of other plants.
Therefore, The secondary level of consumers such as fish will be affected trace amounts of pesticides, like DDT, that run off into lakes, streams and ponds because they live in water and their food is in water. Once the substances are in their water, it will become toxic and can lead to their deaths.
