To ensure proper protection for food during storage the bottom shelf should be at least 3 inches - 3 feet above the ground. This is to protect the food from pests and other organisms that may cause disease and health-problems to people who are going to consume such produce. It is a common practice done in the past and have evolved in the process of manufacturing these days.
Answer:
This is due to the property of contractility.
The techniques that could be employed in sprinting includes:
- begin to run in a more upright position.
- head begins to rise,
- spine elongates and straightens out,
- eyes are fixed onto the end of the sprint lane.
<h3>What are the phases of sprinting?</h3>
Sprinting is a type of forward movement where the athlete puts in maximum force in order to attain maximum speed.
The stages of sprinting include:
- the start
- the acceleration
- drive or top speed
- deceleration
In drive or top speed stage, the aim is to achieve and maintain maximum speed.
The techniques that could be employed in sprinting includes:

- head begins to rise,
- spine elongates and straightens out,
- eyes are fixed onto the end of the sprint lane.

Answer:
It is a challenge
Explanation:
Hello,
It is a challenge because not all people know how to manage the time.
Best regards
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.
