Answer: Option a) the frequency of the homozygous dominants will go down, the frequency of the heterozygous genotype will go down, and the frequency of the homozygous recessives will go up
Explanation: Another name for gene frequency is the allele frequency. It is the percentage of any chromosomes in the population that contains that particular gene or allele. It also shows the genetic diversity that can present in a species.
Answer:
0.
Explanation:
X- linked recessive trait may be defined as the trait that are generally transmitted from the mother to the son. The daughter can express the trait in homozygous recessive condition only.
The woman is heterozygous for the hemophilia condition as his father is haemophilic. She marries with a man that has normal blood clotting. The cross between them is as follows:
Parents: XhX and XY
Progeny : XhX, XX, XhY and XY.
No, daughter will be affected by the hemophilia.
Thus, the answer is 0.
The lymphatic system is involved with the immune and circulatory systems. It's responsible for removing toxins and waste from the blood and fighting illnesses. A way that it works with the circulatory system is by transporting a fluid called lymph, which fights infections, through the capillaries, veins and arteries of the body. If you've heard of "lymph nodes", then you already know one part of the system. These organs are responsible for processing the lymph, and you have quite a few of them.
One organ that is major in the system is the spleen. It's a kinda bean shaped organ located right under your left rib cage above the stomach. I think it's one of those less-known organs, as well. Its job is to make sure your body has the right amount of blood in it, filter red blood cells, and fight infection. That's why if you don't have a spleen, you're more prone to getting sick and I've heard that you'd have to get more vaccines for things that your body normally can fight off on its own. So it's a vital part of the immune system. It processing old red blood cells out and regulating how much blood you have links it to the circulatory system. If your body has old RBCs that are defective or not working anymore, your spleen gets rid of them.
Hope this helps.
Answer:
Tuberculosis bacterium
Explanation:
The macrophages represents a distinct type of white blood cell.
Macrophages function as part of the immune system by engulfing and digesting anything that is foreign to the body's immune system in a process known as phagocytosis. These foreign objects could be in form of microbes or cancer cells.
Tuberculosis is a disease caused my a bacterium known as <em>Mycobacterium tuberculosis</em>. It is a pathogen that directly attacks the macrophages, cells that are supposed to be the first-line responders against microbes and any other foreign object.
<em>The bacterium enters through the alveolar of the lungs and manipulate the host's innate immune response, cellular trafficking and cells death pathway to suit its mission. </em>
Answer:
12. Brain abscesses
13. Cytotoxic agents
Explanation:
I didn't really understand 14 and 15,
if you need an example of cytotoxic agent one of them is Hydrochloric acid which is one of the most common acids
Hope it helps.
