Delta is a type of fibre that transmits signals that are interpreted and perceived as pain.

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.

Explanation:
The correct answer is:
a. was completed in 2003
It was started in 1990, and run until 2003 (so we know that the first answer is correct and the second isn't). It provided a big amount of important information, but it' didn't allow anyone to alter their appearance, as this is not something that can be achieved via genetics.
Answer:
As the MyPlate icon shows, the five food groups are Fruits, Vegetables, Grains, Protein Foods, and Dairy
Explanation:
we can say that our food diet should contain carbohydrates fats protein vitamins minerals
