DaniilM [7]

Answer:

The electrical and diffusion potentials for K+ will be equal in magnitude and opposite in direction.

Explanation:

The cell potential may be defined as the potential difference between the inside of the cell and outside the cell. This difference is important for the transmission of nerve impulse.

The equilibrium condition may be defined as the condition at which  the exit and the entrance of the ions will be equal. As the information in the question, Only potassium ions will move inward and outward of the cell. The potassium ions will move in opposite direction since the equilibrium has been reached.

Thus, the correct answer is option (D).

This is a very vague question but i'd say they are modifying their emotional state
if two animals are held in captivity seperate when they finally meet they will more than likely be hostile to each other because they dont know what a friend is lets take a cat for example dont give a cat a friend and now it sees a interesting laser on the floor and chases it well thats adorable and all but you just taught your cat how to be hostile and hunt and it will do that for the rest of its life well now lets say this cat is 2 and an adult female when she comes across another female or another species of animal she will definitely attempt to fight it because its all she knows

After DNA fragments with matching sticky ends are temporarily joined by complementary base pairing, the union can be made perman
STatiana [176]

Answer:

The correct option is b. DNA ligase

Explanation:

DNA ligase is an enzyme that joins DNA fragments. If two DNA fragments or molecules have complementary ends, the ligase can join them together to form a single and intact DNA molecule, without interruptions. This is because the ligase enzyme seals the space between the molecules to form a single DNA fragment.  

The others enzymes have different functions:

DNA helicase is characterized by separating DNA from double strands into single strands and acts in DNA replication.

ATP methylase plays an important role in DNA replication when determining the beginning of replication that has already been replicated or not.

DNA polymerase is an enzyme that is responsible for catalyzing the polymerization of the new strand of DNA during the replication of this molecule.
