7 0

Answer:

The cholodny-went model was proposed in 1927. This model explains the capability of the shoots to grow in the direction of the sunlight whereas the capability of the roots to grow downwards. The hypothesis suggested that both these directional growth occurred due to the asymmetrical distribution of the plant hormone, auxin. This model has been modified a number of times by other scientists but its general concept is accepted by most of the researchers.

Aleks [24]
It should be taken into consideration the presence of frameshift mutations. Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and consequently in changed protein. But it is known that 3 nucleotides on mRNA code for the specific amino acid. If the number of inserted or deleted nucleotides is 3, it will result in the absence<span> of only 1 amino acid which is not expected to drastically change protein sequence.
Knowing all this, it can be concluded the following:
</span>
<span>-/-/+/-/- <u>OK </u>- Due to 4 deletions and 1 insertion, effectively only 3 nucleotides are missing.
</span>+/-/+ <u>Not OK</u> - Due to 1 deletion and 2 insertions, effectively only 1 nucleotide is added leading to the frameshift mutation.
+/-/+/- <u>OK </u>- Due to 2 deletions and 2 insertions, a number of nucleotides remain the same.
+/+/-/+ <u>Not OK</u> - Due to 1 deletion and 3 insertions, effectively only 2 nucleotides are added and the frameshift mutation occurs.
-/+ <u>OK </u>- Due 1 deletion and 1 insertion, a number of nucleotides remain the same.
<span>- <u>Not OK</u> - Due to 1 deletion, the frameshift mutation occurs.
</span>-/-/-/-/-/- <u>OK </u>- <span>Due to 6 deletions, it will be deleted 2 amino acids and the protein will be nearly normal.</span>
<span>+/+/+ <u>OK </u>- Due to 3 insertions, 1 amino acid will be added in excess.
</span>-/- <u>Not OK</u> - Due to 2 deletions, the frameshift mutation occurs.

EastWind [94]

The question is incomplete as it is incomplete therefore a picture of the complete question has been attached.

Answer:

To be used by the cells for energy

Explanation:

The digestive process of humans digest or breakdown or oxidise the organic molecules present in the food to simple compounds which could be easily utilised by the human body.

The human body composed of tissue and cell requires energy to perform metabolic reactions in the form of ATP which are provided by the digestion of the complex food material.

The macronutrients present in the food thus are digested and absorbed by the cells to perform reactions which could provide energy therefore the selected option is the correct answer.
