Answer:

It is usually of uniform thickness. (Ans. E)

Explanation:

In the plant cell wall primary cell wall is existing between the mid lamella and the secondary cell wall. The structure of the primary cell wall is thin, and flexible in nature and they are made up of pectin, hemicellulose, cellulose.

The primary cell wall is the part of the cell wall that has the capability to enlarges the layers by the mechanism known as an acid growth mechanism, with the help of this mechanism plant cells grow via plant cell wall enlargement at a poor pH level.

Imagine that a mutation in DNA produces a protein with a slightly different amino acid sequence. how would this mutation affect
Lynna [10]

Answer:

It would most likely render the protein nonfunctional or mis-functional.

The mutation could result in three outcomes:

  1. Silent mutation, which changes the codon to the same amino acid. (AAA->AAG, both are lysine). But since the problem specified that it has a "slightly different amino acid sequence," we can assume this doesn't happen.
  2. Nonsense mutation, which changes a codon to a stop codon. This would end the chain of amino acids, making the protein potentially nonfunctional.
  3. Missense mutation, which changes a codon to another completely different codon. This can be harmful, as in sickle-cell disease, where just one amino acid, glutamic acid, is changed to valine.

Oksana_A [137]

Answer:

D. Changes in the environment changed each morph's ability to evade predation in different ways.

Explanation:

The moth species<em> Biston betularia</em> has two color morphs, or variants. One has a speckled white and black color, while the other is all black. Over the period of time, the distribution of moths dramatically changed between 1900 and 1950 in such a way that black morph became dominant but speckled morphs became very much declined in abundance. The reasons behind this change was heavy industrial pollution in UK between 1900 and 1950.

When the environment became very polluted, dark and blackish, the speckled moth had more chanced of getting eaten by predators thats why they declined in number  as compared to black morphs. On the other hand, backgrounds of grime and soot made black morphs less visible to the predators and they survived well. This is an excellent example of natural selection that only those specie better survive that have the ability to cope better with adverse environmental fluctuations.

Therefore, option D is best option.

Hope it help!

What process recharges this molecules so that it can become ATP again
alexdok [17]
<span>By rebonding with another phosphate molecule through oxidative phosphorylation, it becomes recharged and the ADP to ATP process can be restarted. This allows for more cellular energy to be produced, and more metabolic actions to be undertaken. This is the major aspect of cell respiration.</span>
