Answer:
C) is prevented due to growth-inhibiting proteins of oligodendrocytes
Explanation:
Oligodendrocytes are the neuroglial cell and mainly serve to support neurons. These cells also produce a myelin sheath around axons of neurons of the central nervous system. Axons in the CNS display little regrowth or neurogenesis. Inhibition of regeneration is due to several factors such as the absence of a neurolemma and an inhibitory influence of the oligodendrocytes on axon regrowth. For the purpose, the oligodendrocytes produce growth-inhibiting proteins. Axons in the CNS are myelinated by oligodendrocytes and this myelin is one of the inhibiting factors in the regeneration of neurons.
<span>Cartoon or ribbon representation
Most popular form of representing proteins. Colo-coding the different secondary structure elements gives it a more refined look. But no side-chains are shown. Best for comparing overall structure of two different proteins.</span>
Every three nucleotides would compose a codon, which would make 1 amino acid in a polypeptide chain so the answer to your question is C.5. I hope that this is the answer that you were looking for and it has helped you.
Answer:
Mitosis, formation of body cells
Explanation:
Because you only match homologous pairs when you want to produce genetically identical daughter cells, and this is exactly what happens in mitosis. Since body cells are produced through mitosis, this applies too.
The correct answer is C. It is taken in from the air
Explanation:
Carbon dioxide is a gas that exists mainly in the air or atmosphere. Additionally, this chemical compound is required for plants as part of photosynthesis (process to produce energy). In this process, plants take dioxide from the air through the leaves' stomata, which are small spores, use this along with sunlight and water to produce energy, and later release oxygen. According to this, carbon dioxide is taken from the air by plants (option C) while oxygen is given off.
