Explanation:
Answer:
E) founder effect and genetic drift
Explanation:
Dunkers moved to Pennsylvania and inhabited a new area to develop a new population. This new population might not have the same gene pool and the same allele frequencies for all the genes as present in the original population. The change in the allele frequencies of a population due to the colonization of a new area by a few members is called the founder effect.
The small size of the new population of Dunkers present in Pennsylvania was more likely to be affected by any chance event which could have added more uniqueness to their gene pool. This is called genetic drift. Therefore, the genetic uniqueness of their population from all the other populations and from their original population might be the result of founder effect and genetic drift.
If there is no oxygen...many cells die....but some can perform cellular respiration without oxygen too.....they are anaerobic. they usually use organic substance to survive !!!
as acidophilic bacteria survive without oxygen in acids ...so !!!
Answer:
The correct answer is a and e.
Explanation:
Translation is the process by which mRNA is translated into proteins. It occurs in both prokaryotes and eukaryotes. In prokaryotes, transcription and translation occur simultaneously while in eukaryotes translation is a separate process occurs in the cytoplasm after transcription.
The first amino acid incorporated in the polypeptide is methionine in eukaryotes and formyl methionine in prokaryotes. After protein synthesis in both eukaryotes in prokaryotes, post-translational takes place like glycosylation, acetylation, alkylation, etc.
Post translation is important for proteins to provide them heterogeneity and functional activity. Thus, the correct answer is a. the first methionine in eukaryotic translation contains a formyl group and e. many eukaryotic proteins are chemically modified after translation, which is a much rarer phenomenon in prokaryotes.
Answer:
During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.
