Which refers to swelling as a result of inflammation?
Bad White [126]

Answer: Edema

Explanation:

The swelling that is caused as the result of inflammation is known as Edema. Just after an injury takes place the traumatized area becomes red, painful and warm. It also starts to swell.

This swelled area is also known as Edema which is caused due to acute response of acute inflammation.

This response is trigerred by the injured tissues. When the body starts healing then, change in blood flow takes place and swelling is also cured.

But sometimes it is so acute that it restricts the normal blood flow and movement of the affected area.

Genetic engineering can be used to disrupt specific genes in the genome of an organism. Predict how the browning of apple slices
adell [148]

Answer: Fruit will not brown. Browning requires a functional enzyme.

Explanation:

Genetic engineering refers to the manipulation of an organism's genes. Scientists use a variety of molecular tools and techniques to cut up and join genetic material from different species and to introduce this new hybrid DNA into another organisms. <u>The overall goal is to add or remove an organism's genetic makeup for the better, or to transfer DNA code from one species into the other, in order to form new combinations or heritable genetic material.</u>

Enzymatic browning is a reaction that occurs in fruits which results in negative effects on characteristics such as taste, color, and nutritional value. This reaction is a caused by phenolic compounds' oxidation by an enzyme called polyphenol oxidase, which causes the generation of dark pigments. This is often seen in apples which are rich in this enzymes and susceptible to this enzymatic browning.

If through genetic engineering, the gene encoding the enzyme responsible for the apple browing is removed, then this enzyme cannot be produced by the apple. Consequently, apples will not brown<u>,</u> because there will not be a polyphenol oxidase that oxidates the phenolic compounds.
