6 0

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.

How did the frequency of stimulation affect the amount of force generated by the isolated skeletal muscle when the frequency of
Alexxandr [17]

Answer:

When the frequency of stimulation of a muscle increases -without it having the opportunity to relax- a process called summation (addition) occurs, promoting an increase in the generation of force in the isolated skeletal muscle.

Explanation:

Summation is a phenomenon that occurs as a consequence of the arrival of successive stimuli that produce the contraction of the skeletal muscle before it achieves its partial or total relaxation, between subsequent stimuli.

<em>When the summation occurs in the muscle, the force generated on it increases its magnitude proportionally to the number of stimuli received, maintaining the muscle contraction in time</em>.

Tetany is the prolonged contraction of a muscle in an abnormal way, by the summation of stimuli received , as some bacterial toxins can produce. The summation can be temporary -when multiple stimuli reach the muscle in a determined time- or spatial, when the amount of stimuli activates a greater amount of motor units.

How does the sea ice in 2019 compare to the sea ice in 2012 during April?
Katarina [22]

The total amount of sea ice showed a decline from 2012 to 2019. The correct option would be D.

<h3>Graphical illustration</h3>

Looking at the graph, from February to June 2012, there is a decline in the amount of sea ice.

A similar decline in the amount of sea ice can be observed in the year 2019.

However, the sea ice levels for the various months in 2012 remain generally above the sea ice levels in the various months in 2019.

Thus, overall, one can say there is a general decline in the ice level from 2012 to 2019.
