A
The independent variable in an experiment is the variable that influences the other variable called the dependent variable. The independent variable is therefore manipulated to ascertain its effect on the dependent variable.
Explanation:
In this experiment, the air temperature is the independent variable because it is being manipulated to check its effect on the plant's photosynthesis. Probably, the higher the air temperatures, the higher the rate of photosynthesis and vice versa. The rate of photosynthesis is the dependent variable and is what is being measured as the air temperature is being controlled.

Answer:
Single nucleotide deletion
Explanation:
Original DNA sequence:
A T A C G G T A
T A T G C C A T
Mutated DNA sequence:
A T C G G T A G
T A G C C A T C
In the mutated sequence, there is a nucleotide missing. It goes from ATACGGTA to ATCGGTAG. The A nucleotide is gone. This represents a single base pair deletion.
Even though it is only one base, this changes the way the entire sequence is interpreted. The DNA transcribed into an mRNA and then translated into a protein by reading triplet codons which correspond to specific amino acids.
So while the initial sequence would be read as:
ATA, CGG, TA...
The new sequence would be read as:
ATC, GGT, AG...
So the sequence of the protein is completely altered.
