Answer:
I would say that the answer to the question: Blood viscosity is highly variable in healthy individuals under resting conditions, would be, B: False.
Explanation:
Blood viscosity is the density present in the blood due to its charge of cells (red blood cells, white blood cells, and platelets) in relation to the amount of serum, or water, in the mix. This viscosity then, is highly dependent on hematocrit, or the count mostly of red blood cells. There are conditions that can make hematocrit counts rise severely, and make blood more viscous, like extreme temperature conditions, dehydration, or an illness, as well as blood loss. However, in general, under normal conditions, in a healthy person, under resting situations, the hematocrit tends to remain normally at 40%, and blood viscosity remains at a normal level. If hematocrit changes, rises, or falls, then viscosity will also change, but for this to happen, the person must not be meeting resting, and normal, conditions.
Answer:
The correct option is b. myelinated axons from many neurons
Explanation:
White matter is an area which is present in the brain and the spinal cord, that are mainly consists of bundles of myelinated axons, also called tracts. The myelinated axons are the nerve fibres that are surrounded by a lipid-rich substance called myelin.
The presence of the myelin gives the tissue the white colored appearance in contrast to the cerebral cortex which is the grey matter.
Therefore, the myelinated axons from many neurons aggregate together to form the white matter present in the brain and the spinal cord.
Answer and Explanation:
1. The best recommendation to give Jeremy is that he see a doctor immediately, so that his injury is treated correctly and does not cause major problems.
2. We could tell Jeremy that minor sports injuries are small muscle stretches, which return to normal quickly if the correct procedure is applied.
3. Jeremy can determine if the injury was a sprain or strain by looking at the ankle bone. If the bone is out of place, it means it is a strain, if the bone is in place it is a sprain.
4. If it is confirmed that he has suffered a sprain, he should leave the injured ankle elevated to reduce the swelling. He should also apply ice, for 15 minutes and if possible to move his toes.
5. A treatment will always be useful, but it can present long and not as efficient results, but only a health professional can report correctly.
