Answer:
Explanation:
There are several different kinds of assessments of cardiorespiratory fitness such as timed runs, timed walks, and step tests. Using multiple, different fitness assessments gives a more complete picture of the various factors that contribute to an individual's level of cardiorespiratory fitness.

Answer:
the human body requires essential fats and lipids in order to maintain the body. it is impossible to have 0% body fat, unless you are asking for death.
Answer:
An athlete’s resting heart rate may be considered low when compared to the general population. A young, healthy athlete may have a heart rate of 30 to 40 bpm.
That’s likely because exercise strengthens the heart muscle. It allows it to pump a greater amount of blood with each heartbeat. More oxygen is also going to the muscles.
This means the heart beats fewer times per minute than it would in a nonathlete. However, an athlete’s heart rate may go up to 180 bpm to 200 bpm during exercise.
Organic foods are natural food grown without the use of additives and synthetic pesticides. The crop must be harvested by hand is not the condition required.
<h3>What is organic food?</h3>
Organic food is the natural method of the growth and harvest of agricultural food and crops. They promote the principles of ecological balance and the conservation of biodiversity.
They are the crops grown without the addition of synthetic pesticides that are harmful to the crops and the organism that consumes them.
For labelling the food organic it must contain 95 % organic ingredients, produced without the use of pesticides and the animals used must have access to outdoors.
Therefore, option D. crops harvested by hand does not require the government to label food.

Delta is a type of fibre that transmits signals that are interpreted and perceived as pain.
<h3>
Delta fibres</h3>
A delta fibres (also known as A fibres) are a type of sensory fibre. They respond to cold and pressure stimuli, and as nociceptors, their stimulation is perceived as fast/first pain input. Because they are thinly myelinated, they transmit impulses quicker than unmyelinated C fibres but slower than other, thicker myelinated "A" class fibres.
Structure
They have myelinated axons that are thin (2 to 5 m in diameter) and have a moderate conduction velocity, or speed at which a nerve signal moves (2 to 30 m/s). These nerve fibres make up the afferent portion of the reflex arc that causes the body to "draw away" from noxious stimuli because they are linked to acute (sharp) pain (e.g. retracting your hand away from a hot stove). A part of A fibres is also linked to pressure and temperature perception (also known as "cold receptors" in mammals). Contrarily, slow-conducting, unmyelinated C fibres convey gradual, scorching pain.
