The given question is not about true/false. The correct question is:
Question: Sheath of schwann cell containing cytoplasm and nucleus that encloses myelin.......
Answer:
Neurolemma
Explanation:
Schwann cells are one of the two types of neuroglia that produce myelin sheaths. Schwann cells produce the myelin sheath in the peripheral nervous system. These cells produce the myelin sheaths around axons during fetal development. During the process, several layers of the glial plasma membrane surround the axon. The Schwann cell’s cytoplasm and nucleus form the outermost layer. On the other hand, the inner part is composed of multiple layers of Schwann cell membrane and is called the myelin sheath. The outer nucleated cytoplasmic layer of the Schwann cell that encloses the myelin sheath is called the neurolemma.
The skin acts as a barrier for protecting the body from the harmful things such as sun rays, moisture, cold.
<u>Explanation:</u>
Skin plays an important role in regulating body temperature. It helps to prevent harmful substances enter into our body, and does not allow to loss water in our body. Its form the barrier that prevents harmful substances and microorganisms enter in our body.
Our skin is the protecting layers and against loss of water and blood from our body. Its help us to maintain the constant body temperature. The important role of the skin us to protect our body from the ultraviolet rays.
Lipids are hydrophobic macromolecules
The answer is histone
acetylation decreases with age, so sodium butyrate may improve memory in older
mice
<span>This
is because Histone deacetylase (HDAC) inhibitors increase histone acetylation
and enhance both memory and synaptic plasticity of brain neurons. It also regulates
cell proliferation and neuroblast differentiation in the dentate gyrus hence
improve memory function especially the hippocampus-dependent memory. </span>
Answer:
Not sure about the sodium but you might be referring to the Chloride Shift in the lungs.
