Answer:
With respect to the composition of DNA, in an analysis it can be found that the proportions of nucleotides are A + C = G + T (option a).
Explanation:
The proportion of nucleotides in a DNA molecule can be established according to the sequence of these nucleotides on both complementary strands, since the purinic bases of one strand are complemented by the pyrimidinic bases of another:
- <em>Adenine is complemented with Thymine A=T</em>
- <em>Guanine is complemented with Cytosine G=C</em>
From this we can deduce that in a DNA molecule with two chains there will be the same amount of adenine and thymine, as well as the same number of guanine with respect to cytosine, so:
<em>     A + C = G + T</em>
An example of this would be a known DNA molecule (hypothetical), with 5 molecules of Adenine and 7 molecules of Guanine. In this case there are 5 Thymines, complementary with Adenine, and 7 Cytosines like Guanine:
<em>     A + C = G + T</em>
<em>     5 + 7 = 7 + 5</em>
 
        
             
        
        
        
Answer:
Answer ...... would have photosynthetic pigments.
Explanation:
In a short explanation, the collective term for the stack of thylakoids within the chloroplast of a plant cells is known as GRANUM.
Note that , chloroplasts are made up of the chlorophyll, which are the green pigments responsible for photosynthesis.

Answer:
solar energy
Explanation:
Solar energy mainly drives the processes that happen at the earth's surface, like the water cycle, wind, weathering, erosion, and growth. Energy from inside the earth is responsible for internal processes like volcanism, metamorphism, and plate tectonics.
