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.
Eighty percent of all collisions involve driver distraction within three seconds of the collision. Distracted driving is when an even, person, activity, or object draws a driver's attention away from the driving task. There are four categories of distarction; including cognitive, visual, auditory, and biomechanical disractions.
"Neurons" are the functional unit of the nervous system; it is the specialized cells transmitting nerve impulses
Hope this helps!
G always pairs with C...So, if there is 30% G, then there's 30% C...which is 60%...that leaves 40% A+T - and you have to split this up too - so 20% Thymine (T) and 20% Adenine (A).
Answer:
Plants photosynthesize <em>only in the light but respire in light and dark</em>.
Explanation:
The reactions of photosynthesis occur only during the day. This is because sunlight is used for converting water and carbon dioxide into oxygen and glucose in the presence of sunlight. The light of the sun s the energy force which drives this reaction.
However, the reactions of respiration continue at day and night. The reactions of respiration do not require light energy from the sun.
