The correct answer is: E) provide the defense for the CNS
Astrocytes are star-shaped cells found in central nervous system (brain and spinal cord) .Some of their functions include:
• Support of neurons by supporting endothelilal cell of blood–brain barrier,
• Provide nutrients to neurons
• Maintain ion balance and thus controlchemical environment around neurons
• Repair of injuries in the brain
• the secretion or absorption of neural transmitters…
The cells that provide the defense for the CNS are called microglia. Those cells are also glial cells, derived from macrophages and thus, part of active immune defense.

Production of ATP in the absence of oxygen is called anearobic respiration. Under anaerobic respiration,two molecules of ATP is produced from one molecule of glucose. These ATP are used for energy production by the contracting muscles.
Answer:
Elevated uric acid levels lead to a condition known as "Hyperuricemia."
Explanation:
This condition occurs when there is an excessive presence of uric acid in the blood. It can be divided into:
- Primary hyperuricemia
- Secondary hyperuricemia
Primary hyperuricemia occurs when the kidneys are not able to eliminate uric acid in an efficient/proper way. This can be due to the consumption of foos that are very high in purines. For example, liver, gravy, alcoholic beverages, and some vegetables such as spinach and asparagus.
Secondary hyperuricemia may occur to several possible reasons. For instance, kidney disease, in which the kidney is not able to eliminate uric acid; chemotherapy, which may lead to the accumulation of uric acids; or medications that increase the level of uric acid in the blood.
Symptoms include:
- Fever.
- Extreme and abnormal fatigue.
- Joint inflammation.
- Urination problems.
- Kidney stones.
To prevent this disease and as part of a treatment (along with medications prescribed by a doctor), a patient should opt to consume foods that are low in purine, such as lettuce, tomatoes, cereals, fruits, milk, eggs, amongst others.
