Answer:
A. vital capacity
Explanation:
<u>Vital capacity is defined as maximum amount of the air that a human can expel from lungs after the process of maximum inhalation. In other words, its is the volume of the lung which represents the maximum of the total volume which can be exchanged with the air.
</u>
It can be measured by using a wet or a regular spirometer. A normal adult has between 3 to 5 litres of VC. Vital capacity of the human depends on the age, sex, mass, height and ethnicity.
In most neurons the resting potential has a value of approximately-70mV
Answer and Explanation:
The steps of the sliding filament theory are:
Muscle activation: breakdown of energy (ATP) by myosin.
Before contraction begins, myosin is only associated with a molecule of energy (ATP), which myosin breaks down into its component molecules (ADP + P) causing myosin to change shape.
Muscle contraction: cross-bridge formation
The shape change allows myosin to bind an adjacent actin, creating a cross-bridge.
Recharging: power (pulling) stroke
The cross-bridge formation causes myosin to release ADP+P, change shape, and to pull (slide) actin closer to the center of the myosin molecule.
Relaxaction: cross-bridge detachment
The completion of the pulling stroke further changes the shape of myosin. This allows myosin and ATP to bind, which causes myosin to release actin, destroying the cross-bridge. The cycle is now ready to begin again.
The repeated cycling through these steps generates force (i.e., step 2: cross-bridge formation) and changes in muscle length (i.e., step 3: power stroke), which are necessary to muscle contraction.
It tells the audience if the results support or contradict the hypothesis
Explanation:
When a scientist describes the materials that she used and how she performed her experiments, it tells the audience if the results supports or contradicts the hypothesis.
- A hypothesis formulation helps to test a scientific claims.
- Experiments are usually hinged on well designed hypothesis.
- From the hypothesis, one can be sure the experiment is tuned and designed within the scope of the observation desired to be tested.
- This is why the materials used and procedures followed in an experiment can tell if the results supports or contradicts the hypothesis.

Gandhi's most basic principles apply everywhere in life, these includes unity of mind, body and soul, such that one should never do anything with their body that is not right with their mind or with their mind that is not right with their soul. In addition, selflessness, service to others and faith in a superior spiritual life to our life on earth are among other aspects that one needs to apply in real life.
