Arlecino [84]

Answer:

<em>The correct option is D) Ethyl alcohol is produced.</em>

Explanation:

Fermentation can be described as a process by which energy is extracted by organisms such as bacteria and yeast.

Sugars are converted into alcohol by this metabolic process occurring in certain microorganisms. There are two main types of fermentation:

Fermentation which takes place in the presence of oxygen is termed as aerobic fermentation.

The process of fermentation which occurs in the absence of oxygen is termed as anaerobic respiration.

Hence, as alcohol will be produced from both types of fermentation, optic C is correct.

Phantasy [73]

Answer:

Yes

Explanation:

In the scenario being described in the question it can be said that Yes, the friend's behavior would be considered binge drinking. This is due to the fact that consuming four drinks or more for women is considered binge drinking, and she had 5.  Binge Drinking is defined as when a pattern of drinking that brings a person's blood alcohol concentration (BAC) to 0.08 g/dl or above, which for men is 5 or more drinks, and for women it is 4 or more drinks in less than 2 hours.

In fermentation the molecules of NADH are________while the organic molecules are _________.
LuckyWell [14K]

Answer:

The correct answer is option C- "oxidize, reduce".

Explanation:

Fermentation is a process analogous to cellular respiration and, just like the latter, it involves oxidization and reduction of molecules with the final purpose of producing energy. During the process of fermentation nicotinamide adenine dinucleotide + hydrogen (NADH) is oxidized to its original form of NAD with a plus charge; while other organic molecules such as piruvate are reduced.

Is it possible for plant breeders to develop a true-breeding pink-flowered snapdragon?
abruzzese [7]

Answer:

No.

Explanation:

Pink flower colour in snapdragon is as a result of incomplete dominance. The pink flower colour has no allele in nature. Instead, the pink colour results from incomplete dominance of the allele that codes for red flower colour over the allele that codes for the white flower colour.

Assuming that the allele for red flower colour in the plant is R and the allele for white flower colour is r, true breeding red and white flower colour plants will have the genotype RR and rr respectively. In heterozygote state (Rr), the phenotype is usually pink, showing that the R allele has incomplete dominance over the r allele.

<em>Hence, there is no way for plant breeders to develop a true-breeding pink-flowered snapdragon. without some genetic manipulations/mutation.</em>

Explain why mutations may or may not affect phenotype
Svetlanka [38]

Answer:

Explanation:

Mutations may or may not affect the phenotype because they can occur in coding or non coding areas of the DNA. If they occur in coding areas of the DNA, the protein that is coded in that part could be processed incompletely or have a different amino-acid in some part of its structure, this would affect the phenotype. If they occur in non coding areas, this would have no effect on the phenotype.
