Answer:i think it would be c
Explanation:
All matching codons in all organisms DNA code for the same amino acids.
Option D.
<h3><u>Explanation:</u></h3>
Codons are defined as group of three nucleotide bases that forms a triplet, and codes for a particular amino acid.
There are four nitrogen bases, so four possible nucleotides. Among them, 3 are stop codons, rest 61 are codons denoting the 20 amino acids. Codons are discrete, meaning no same codon codes for more than 1 amino acid.
And these codons are universal. It means, like AUG denotes for amino acid methionine, and that is same in bacteria, as well as in all organisms. So they are universal.
Pot A that contained no fertilizer or compost will serve as a control in this experiment.
<h3>What is Fertilizer?</h3>
Fertilizer may be defined as any chemical or natural substance which is added to the soil with the intention to enhance the soil productivity.
Pot B contained fertilizer, while pot C contained compost, they will definitely grow more than pot A, but pot A serve as a control for this experiment because it does not contain any added resources into it. Hence, it grows naturally.
Thus, it is well described above.

Movement of particles from a region of a high concentration to a region of low concentration
Answer:
The correct answer is Active transport moves substances against the concentration gradient.
Explanation:
The principle difference between active transport and facilitated diffusion is that active transport helps in the movement of various substances in the uphill direction which means against the concentration gradient.
In simple words active transport helps in the movement of substance from the region of low concentration to a region of high concentration.
On the other hand during facilitated diffusion substances move along their concentration gradient which means from the high concentration region to the region of low concentration until the concentration of both sides become same.
