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).
Answer:
AZT inhibits reverse transcriptase enzyme.
Explanation:
AZT inhibits reverse transcriptase enzyme that is used by the virus to make a DNA copy of its RNA. This Azidothymidine prevent reverse transcriptase enzyme from doing its function properly. Due to absence of this enzyme, the HIV virus is unable to make copies of its DNA and this Azidothymidine stops the life cycle of the virus and slows the growth of AIDS disease so that's why this drug was considered effective against HIV virus and used in the treatment of AIDS disease.
Answer:
e. All of the above are False.
Explanation:
A tRNA is a transfer RNA that carries amino acid from the cell pool to the mRNA-ribosome complex. The anticodon sequence of tRNA is complementary to the mRNA codons and bind to the respective amino acids. None of the tRNA has anticodon for stop codons and therefore, as soon as the ribosome reaches stop codon, protein translation terminates.
AUG is the initiation codon for protein synthesis and codes for methionine when present at a site other than the start site. The initiation codon is often preceded by an untranslated sequence, also called leader sequence. The ribosome moves along the mRNA in 5' to 3' direction in a GTP dependent manner to facilitate elongation of the polypeptide chain.
Answer:
Experimental groups: type of dogs
Dependent variable: hearth rate
Independent variable: the amount of caffeine
Explanation:
The dependent variable is the variable being measured or tested in a given study, while the independent variable isn't changed by the other variables. In this case, the heart rate is dependent on the amount of caffeine, which is then the independent variable. The experimental groups are the groups exposed to the independent variable.
