Answer:

A mutation in his offspring

Explanation:

A mutation can be described as any change which occurs in the DNA of an organism. Mutations can be either heritable or non-heritable

If a mutation occurs in the gamete cells of a male, the mutation will be heritable and will occur in his offsprings.

Other options, like option D, is not correct because a mutation in the gamete cells will not cause a mutation in the somatic cells. Gamete cells are the sex cells and hence mutation will arise in the sex cells.

Answer:

As one goes up the other does as well for the first 2 but they aren't proportional (it is not simple cause and effect as there is a lot of factors)

The last question is to decrease their emissions as rising temperature is being effected by rising CO2 levels and rising temperature can cause a feedback loop causing more rising temperature

A scientist discovers a cell that has chloroplasts, cytoplasm, DNA, and a cell membrane. Which statement best describes how the

Zina [86]

The correct answer is The cell is eukaryotic because it has chloroplasts. Prokaryotic cells don't have chloroplasts as they are only found in eukaryotic cells. The closest thing there is to chloroplasts are the cyanobacteria who function similarly and also photosynthesize but are in the end not chloroplasts themselves.

Which of the following sequences shows a frameshift mutation compared to the wild-type mRNA sequence?

Butoxors [25]

Option C:

B. wild-type 5-AUGCAUACAUUGGAGUGA-3 mutant 5'-AUGCAUACAUCUGGAGUGA- 3'

Explanation:

A frameshift mutation is a genetic mutation such that the triplet nature of gene expression by codons, the insertion or deletion occurs in such as way that it alters the complete sequence of 3 codon sets and can change the reading frame, resulting in a completely different translation from the original.

As it is pertinent to understanding that all genes are normally translated in sets of 3 codons, which typically describes and explain a unique amino acid sequence. Thus, if a frame shift mutation occurs, it can affect many amino acid sequences and finally the entire protein.

If we look at option B:

wild-type 5-AUG CAU ACA UUG GAG UGA-3

mutant 5’- AUG CAU ACA UCU GGA GUG A-3’

An insertion of a base Uracil showed at the end of 3rd codon which affected and altered the whole sequence of codon triplets. This changed all next codons and finally all next amino acids will be altered.

Bad White [126]

Answer:

The selenium particles when coated on paper towels were extremely effective and continuously inhibited (about a 90% reduction) the growth of gram-positive bacteria including S. aureus and S. epidermidis after 24, 48, or 72 hours.
