In the branch of mechanics, the aspect of acceleration is considered to be a property of the vector. And acceleration always occurs in a specific positive direction.

The formula for determining acceleration is change in the rate of velocity over a specific time, and is therefore measured as the ratio of delta velocity by delta time unit.

$\text {acceleration}=\frac{\text {velocity}}{\text {time}}=\frac{\left(\frac{\text {distance}}{\text {time}}\right)}{\text {time}}=\frac{\text {distance}}{\text {time}^{2}}\left(\mathrm{m} / \mathrm{s}^{2}\right)$

The unit of acceleration is distance per time unit squared or m / second squared.

The creation of DNA fragments with ends that can join with other DNA is achieved by the use of restrictive enzyme analysis.

<h3>What are restriction enzymes?</h3>

They are enzymes utilized in genetic engineering or gene recombination technology to cut DNA at some specific points in other to have sticky ends.

The sticky ends DNAs are able to join with other DNAs using these ends. Another enzyme (Ligase) is utilized to join the DNA back once the desired DNA has been inculcated.

The Food and Drug Administration has legal oversight over most food products and permits some health claims on food labels. The

Igoryamba

Answer:

Reduced risk of neural tube defects- diet adequate in synthetic form of folate
Reduced risk of hypertension and stroke- diet low in sodium and high in potassium
Reduced risk of cardiovascular disease- fatty acids from oils present in fish
Reduced risk of some types of cancer- diet rich in fiber

Explanation:

As you may already know, the adequate intake of certain nutrients is very beneficial to our body and to improve and maintain our health. That's because these nutrients act in the construction of essential molecules to keep our body functioning in a healthy and adequate way. Among the numerous nutrients necessary for our health, we can mention that the adequate intake of folate has the ability to reduce the creation of possible defects in the neural tube, while a diet rich in potassium can reduce the risks of hypertension, especially if accompanied by a low sodium diet. Following this same reasoning, a diet rich in fiber can reduce the risk of cancer, in addition to promoting good bowel function. Last but not least, a diet rich in fatty acids from fish can reduce cardiovascular disease.
