Answer:

Its primary role in red blood cells is to maintain levels of red blood cells with low levels of this compound are more suceptible to oxidative damage.

Explanation:

Pentose phosphte pathway helps in the formation of reducing equivalent named NADPH.

  The so formed NADPH is used to maintain a normal cellular level of glutathione which act as antioxidant.

 As glutathione is not mantained in its normal level, it ability to reduce to adverse effect of hydrogen peroxide is cut down.

  As a result cell is more suceptible to oxidative damage.

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.

enot [183]

I am going to assume you meant "chloroplasts" instead of "Hloroplasts"

Your answer will be plant cells

Chloroplasts makes the energy for the plant by conducting photosynthesis, therefore, they are only found in plant cells.

Many tropical zooplankton have elaborate spines. These have been interpreted as either a defense against predation or a means to
anastassius [24]

Answer:

Means to increase drag and prevent sinking is the correct answer.

Explanation:

Plankton avoid sinking by increasing their surface area and decreasing their density. Spines slow down sinking by adding surface area without increasing density. Defense against predation would be to sing below. Not the opposite.

Mrac [35]

I belive the answer would be "A" because the cell would be trying to delute the solution on the outside, and strenghting the solution on the inside.
