The correlation would be a "positive" correlation. It's not meaning that it's a positive thing to smoke. The graph suggests that the more cigarettes that are smoked per day, there's a more positive suggestion that your risk of lung cancer increases.
The correct answer is: D. Alcohol fermentation
Alcohol fermentation is a form of anaerobic where the simple sugars such as glucose or fructose are converted into energy (ATP) and the products of this reaction are ethanol and carbon dioxide. Alcohol mechanism is performed by yeast and some fishes. This is a mechanism used for the production of alcoholic beverages.
Answer:
A trait that is neutral in one environment may be advantageous in another.
Explanation:
Neutral variation refers to the variation (either genetic or phenotypic variation) which is unaffected by natural selection. Neutral variation is known to increase genetic variation, which is a prerequisite to evolutionary change. An allele may be neutral in one environment and beneficial (or deleterious) in another. In consequence, neutral variation in one environment may increase the response to selection in different environmental conditions.
The first one: A mutation may cause a change that codes for the same amino acid. It is not possible (or likely) that the transcription will skip over the mutation. Mutations, especially large frameshifts, are important. It does not matter how much proteins are replicated. A mutation in the DNA sequence will affect the mRNA.
