Answer:
Today's chance is what I was taught
Answer:
False
Explanation:
Prokaryotes do not have a nucleus.
This means their DNA is not enclosed in a nucleus and instead is in the cytoplasm.
On the other hand, eukaryotes have nuclei, so their DNA is enclosed within a nucleus.
So, this statement is false.
Answer:
Society is largely responsible for how funding is spent. Members of society can choose whether or not to support government funding for certain research.
<span>A polypeptide is a single linear chain of many amino acids, held together by amide bonds. A protein consists of one or more polypeptides (more than about 50 amino acids long). An oligopeptide consists of only a few amino acids (between two and twenty). </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.
