Answer: Nitrogen-fixing Bacteria
Explanation:
In the Nitrogen cycle, nitrogen fixing bacteria are very important in ensuring that plants get nitrogen to enable them grow and as animals have to eat plants, these bacteria are essential for our survival as well.
Plants are unable to use atmospheric nitrogen but nitrogen-fixing bacteria are able to synthesize ammonia from atmospheric nitrogen. They can then convert this to Nitrites and Nitrates which are more useful to plants and animals by extension.
Answer:
Thick diameter, Myelinated
Explanation:
A alpha neurons conduct action potentials faster because of their large axon diameter and myelin.
- The large diameter is less resistant to the flow of ions and allows for faster conductivity.
- The myelin sheath is a layer of fat acting as to insulate the axon which helps increase signal conductance.
