Answer:
Hello. You did not enter the answer options, but the factor that most directly influences a measurable result in an experiment is the manipulation of the variables.
Explanation:
In an experiment, the manipulation of variables becomes highly important so that it is possible to measure, that is, evaluate the result. This is because it is the variables that express values that represent the characteristics that are being analyzed and studied within the experiment. Therefore, the manipulation between them must be done in a very rational and balanced way so as not to modify the values shown by them, changing the data and generating false or immeasurable data.

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.
