In the FITT principle, the choice of swimming instead of walking would be an example of _____.A. time B. intensity C. frequency
kifflom [539]

Answer:

D.type

Explanation:

<em>FITT principle is a guideline for an effective exercise program depending on the main aim of the program. The F stands for frequency, I stands for intensity, the first T stands for time while the last T stands for type.</em>

Frequency is a measure of how often the exercise is carried out, intensity is a measure of how rigorous the exercise is, time is a measure of the duration of the exercise while type refers to the different kinds of exercise that is carried in the program.

Swimming, walking, jumping, cycling, weight lifting, etc. are different types of types of exercise.

Hence, the choice of swimming instead of walking is an example of type as far as FITT principle is concerned.

<em>The correct option is D.</em>

Which statement best describes the events responsible for the phase represented by the letter B in the figure?
Gemiola [76]

Answer:

opening of sodium channels

Explanation:

Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions (Na+) through a cell's plasma membrane. Sodium channels are the founding members of ion channel super-family that includes voltage-gated calcium channels, TRP channels, voltage-gated, inward rectifying, and two-pore-domain potassium channels, and cyclic nucleotide-regulated CNG and HCN channels. When the neuron becomes stimulated the voltage gated sodium channels begin to open and the membrane potential begins to slowly depolarizes and sodium enters the cell down its concentration gradient.

olga nikolaevna [1]
<span>The answer would be:
Jellies
Salt cured meats
Honey

High osmotic pressure can be used as a natural preservative. In high osmotic pressure, the microbes will hardly survive as their surrounding concentration is too high and induce severe osmosis. The osmosis will take the microbes water, makes it shrink continually lead to the microbes death. 
In those 3 foods, there is a high concentration of sugar or salt that increase the osmotic pressure.</span>
