Adenine, Guanine, Cytosine, Thymine?
Answer:
The substance moves from low to high concentration, against the concentration gradient.
Explanation:
When molecules move from high to low concentration, it is known as Diffusion. It moves with the concentration gradient and does not require energy.
However, when molecules move from low to high concentration, it is against the concentration gradient and cannot proceed without Energy. This process is called Active transport.

Answer:
A buildup of sticky mucus on the outside of the cell
Explanation:
The deletion of the codon means that the protein the gene codes for is missing one amino acid.
That protein acts as a Cl⁻ channel in the cellular membrane and controls the movement of water in the tissues.
The water produces thin, freely flowing mucus. Without the water, a coating of thick mucus builds up on the outside of the cell.
