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.
Various cicada species erupt to reproduce at various times. A prime example of temporal isolation is this. The frog species Rana aurora and Rana boylii exhibit temporal isolation as a result of variations in seasonal breeding. Although both species live in the same geographic areas, their mating seasons are different.
<h3>What is temporal isolation ?</h3>
When many species reproduce at various periods, there is a condition known as temporal isolation. Three different orchid species, for instance, coexist in the same rain forest. Every species contains flowers that only bloom for a single day and need to be pollinated on that day in order to generate seeds.
- Due to differences in fertility or mating timing, such as having various mating seasons, species cannot interbreed due to temporal isolation. Due to different mating practises or rituals, behavioural isolation prevents species from interbreeding.

Answer:
eukaryotic and prokaryotic cells.
Answer: Acid-fast and Gram
Explanation:
The gram stains peptidoglycan and the acid-fast stain stains mycolic acid, which are both in the cell wall.
