I believe <em><u>B.</u></em><em>)</em><em><u> The hormone cortisol suppresses the immune system and is produced when the body is under stress.</u></em><em> </em>is your answer.
<span>The cell cycle is divided into two main parts interphase and mitosis. Mitosis is when the cell divides and this process is taken up by the process of dividing. Interphase is broken down into several phases: G1, growth occurs (cytoplasm increases); S, DNA synthesis (replication) occurs; and G2, growth occurs (cytoplasm increases and organelles are replicated).
So the answer is b) Cytoplasm increases, and organelles and DNA are replicated</span>
Answer:
B) astrocytes
Explanation:
Cells other than neurons that play an important role in the normal functioning of nervous system are called Neuroglia or glial cells.
Satellite cells, astrocytes, schwann cells and oligodendrocytes are all examples of glial cells.
⇒Satellite cells provide protection and nutrition to cells in peripheral nervous system ( peripheral nerves and ganglia).
⇒<em><u>Astrocytes</u></em> play an important role in central nervous system (brain and spinal cord). They provide protection to neurons, scavenge ions, form the blood-brain barrier and also maintain extracellular environment suitable for neuronal functioning.
⇒Schwann cells are found in the peripheral nervous system and myelinate the axons of neurons.
⇒Oligodendrocytes are found in central nervous system and produce myelin sheath which myelinates (insulates) axons of neurons. Their function is similar to schwann cells but in the central nervous system.
From the above discussion it is clear that the answer is B) Astrocytes as these maintain a suitable chemical environment for the neurons.
No, for the reason that, agar will not evaporate when it is in a solid state. Agar is a combination of two components, namely, the agaropectin, which is a heterogeneous combination of tinier molecules and another called the linear polysaccharide agarose.
Would the correct answer be A
