Answer:
a. insulation
Explanation:
The myelin sheath provides increased cell isolation (increased membrane resistance) because there are no membrane leakage channels in which there is myelin.
In addition to no membrane leakage channels, there is also virtually no type of membrane channel when there is myelin sheath (eg sodium and potassium pumps), which causes the cell a lower need for protein synthesis, or that is, less energy expenditure.
The geologic features that help scientists to determine the relative ages of rocks by their positions include index fossils, intrusions, and cross-cutting relationships (Option d).
<h3>What does geological age mean?</h3>
The expression geological age refers to the relative age of a given rock and or fossil (i.e. a piece or trace of dead organism) in a geological time scale.
In conclusion, the geologic features that help scientists to determine the relative ages of rocks by their positions include index fossils, intrusions, and cross-cutting relationships (Option d).

B.the mass of carbon dioxide plus water is less than that of paper plus oxygen.
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
The phenomenon validate the Law of Conservation of Energy is "
<span>The light energy travels through the water until it is reflected or absorbed. "</span>
Plants take in that carbon dioxide<span> from the air, and take in water (H2O) as well. Photosynthesis produces a chemical reaction that creates glucose, or C6H12O6, out of CO2 and H2O.
Hope this helps!
