Answer:
The sun (abiotic) affects the grass, trees, flowers, etc. by giving off its energy to the plants so they can grow.
Another example is water (abiotic) affects mostly every biotic factor such as humans, plants, or animals because all living things need water to survive.
c i think but im not entirely sure to be honest with you
Energy equals mass times the speed of light squared.
B.) Water because snow, hail, and sleet are all water when melted.
Answer:
480 nucleotides comprise this molecule of dna
Explanation:
According to Chargaff rule,
- Adenine is paired with thymine
- Cytosine is paired with guanine
Given in the question
Adenine residue = 120
Cytosine residue = 120
So, [A] = [T]
i.e. [A =120] = [T=120]
again, [C] = [G]
i.e. [C=120] = [G=120]
hence, total number of nucleotides present
=> [A] + [T] + [C] + [G]
=> 120 + 120 +120 +120
=> 480.
