Answer:
Since sickle cell disease is a disorder with an autosomal dominant inheritance pattern, and in light of the lack of data, it could be said that the only way for Pat and Tracy to have a child with sickle cell disease is for both of them to be healthy carriers of the gene, with a 25% probability.
Explanation:
Considering that both Pat and Tracy each have a sibling with a sickle cell trait and that both they and their parents are healthy, it must be assumed that some of their parents are healthy carriers:
- Pat and Tracy do not have sickle cell trait. In this case, there is no chance that they will have a child with sickle cell disease.
- Either Pat or Tracy has the trait, but the other does not. It is possible that at least one of their children is a healthy carrier.
- If both Tracy and Pat have sickle cell trait, the chances of having a child with sickle cell disease are:
Alelles R r
R RR Rr
r Rr rr
RR: healthy (25%).
Rr: healthy carrier (50%).
rr: sickle cell disease (25%).
<em>If Pat and Tracy are healthy carriers of the gene that determines sickle cell disease, the chance of having a child with the disease is 25%</em>.

Answer:
The correct answer is A. inflammation
Explanation:
Inflammation is the defense mechanism of the immune system which is non-specific and part of the innate immunity of the body. Inflammation is the reaction against any cell injury.
Inflammation is categorized by heat, pain, redness(erythema), and swelling(edema). These changes occur because of the result of the increase in local blood vessel diameter which leads to increase of flow of blood that results in heat and redness.
The transport of fluids and proteins takes place at the injury site which causes swelling and pain. Therefore the right answer is A. inflammation.
Answer:
Anaerobic exercise is a type of exercise that breaks down glucose in the body without using oxygen, as anaerobic means “without oxygen”. In practical terms, this means that anaerobic exercise is harder but shorter than aerobic exercise
Explanation:
because that is what it is
-Surface area to volume ratio. (surface area / volume)
-Nucleo-cytoplasmic ratio.
-Fragility of cell membrane.
-Mechanical structures necessary to hold the cell together (and the contents of the cell in place)
