Answer:

The correct answer would be the first option.

Mitosis is a type of cell division in which sister chromatids of the chromosomes are separated into two daughter cells.

Each cell gets the same number of chromosomes as present in the parent cell. It is used in the cell or tissue repair and growth.

Meiosis is a type of cell division which includes two sets of divisions; meiosis I and meiosis II.

Meiosis I includes the division of homologous chromosomes whereas meiosis II includes the division of sister chromatids.

It results in the formation of four daughter cells from a single parent, each daughter cell contains half the chromosomes of the parent cell.

It helps in the production of gametes in sexually reproducing organisms.

Eduardwww [97]

Answer:

c. in renal dysfunction, dosage reduction is necessary to avoid seizures

Explanation:

Imipenem is an antibiotic which is given in combination with cilastatin. It is used to treat pneumonia, joint infections, urinary tract infections, sepsis etc. It kills bacteria by interfering with its cell wall formation process. It is metabolized in kidney reducing its half life so cilastatin is given with it to halt its renal metabolism.

Imipenem belongs to carbapenem family of antibiotics. Carbapenem antibiotics can cause seizures specially in people with nervous system disorders or renal failure. Dose must be reduced in patients with renal (kidney) dysfunction otherwise patient's kidneys will be damaged more and since they are already in weak state, it can prove dangerous to the patient.
