Answer:
1. Based on their physical features and conduction properties
2. 80m/s to 120m/s
3. Has both sensory fibers and motor fibers
4. Group B conduct at 3m/s to 15m/s
5. Group C conduct at 0.5m/s to 15m/s
6. They generally have low conduction velocity and are polymodal
Explanation:
Axons were know to have different thickness and this differences were thought to relate to the speed at which the action potential could travel. This hypothesis was proved by Erlanger and Gasser.
Answer:
Populations are influenced by fluctuations in any of the abiotic cycles. The fluctuation of seasonal cycles can cause populations to hibernate, migrate, or breed. Organisms hibernate as a result of seasonal fluctuations that cause them to have a limited resource supply.
<span>The emt is appropriately sizing the airway when she measures <u>the distance from the nose to the earlobe.</u>
These emergency medical technicians are obviously trained when it comes to these medical issues, and know how to properly size the airway. In this case, when it comes to the nose airway, this distance between the nose and the earlobe is the way to go.</span>
The right answer is Calcium
99% of the calcium is located in the bone, ensuring the skeletal strength and the hardness of the teeth.
In children and adolescents, it promotes bone growth; in young adults, it participates in the maintenance of bone capital; in the elderly, it contributes to the prevention of osteoporosis.
Beside the bone, calcium has other functions like blood coagulation, muscle contraction, nerve conduction, activation of certain enzymes.
Adequate calcium intake - consistent with the recommended dietary intakes - would have a preventive effect against high blood pressure.
