Dna has unique properties that allow it to accurately retain genetic information, even after multiple rounds of replication. one
bonufazy [111]
There are four different bases that make the DNA molecule:
Adenine, Cytosine, Guanine, and Thymine.
Due to chemical properties of the bases, there are two pairs of bases that are complementary, Adenine and Thymine and Guanine and Cytosine.
So, if we have 16% of Adenine, there must be the same amount of Thymine, since they only appear in a pair.
16% of Adenine + 16% of Thymine - 32 %
the rest of the abundance of the bases can be calculated by subtracting the 32% out of the 100%: 100-32 = 68
So, Guanine and Cytosine make up 68% of the bases, and a half of that number is the amount each of the bases has in the total amount. 68/2= 34
16% Adenine -  16% Thymine
34% Guanine - 34% Cytosine

Over a 24-hour period, which factor would have the LEAST effect upon the rate of photosynthesis in a geranium plant
snow_tiger [21]

Answer:

This question lacks options, the options are:

A. Concentration of carbon dioxide in the air

B. Quality of nitrates in the soil

C. Wavelengths of light

D. Availability of water in the soil

The answer is B

Explanation:

Photosynthesis is the process whereby cells of autotrophic organisms manufacture their food in the presence of sunlight. The rate at which the process of photosynthesis occurs, however, is dependent upon certain factors including the concentration of reactants (water and carbon dioxide), availability of light source etc.

Among the options, the concentration/availability of light, carbon dioxide and water, which are key reactants of photosynthesis, will have greater effect on the rate at which the process occurs than the availability of nutrients (nitrates) in the soil. Hence, the quality of nitrates in the soil will have the LEAST effect upon the rate of photosynthesis in a geranium plant.

Neporo4naja [7]
Nitrogen is an important part of our bodies. Amino acids all contain nitrogen and these are the building blocks that make up the proteins in your hair, muscles, skin and other important tissues. Nitrogen is an important part of your DNA, which defines what you are like in many ways.
