Answer:
Option-A
Explanation:
β-Lactam antibiotics are the antibiotics that contain β-Lactam rings in their structures like in cephalosporins and penicillin.
The antibiotics act by inhibiting or disrupting the process of cell wall formation in the bacteria which is mediated by an enzyme called penicillin-binding proteins.
To bind covalently to the PBP proteins, the antibiotic has to diffuse through the bacterial cell wall. since the gram-negative bacteria contain an additional lipopolysaccharide layer which decreases the penetration of the antibiotic, therefore, the gram-positive bacteria lacking the additional layer are more susceptible than gram-negative bacteria.
Thus, option-A is the correct answer.
The answer is (A). Hope this helps
Answer:
Meiosis 1 better mirrors the process of mitosis.
Explanation:
During the process of mitosis, the somatic cells of the body replicate to form two daughter cells which are identical to the parent cell. In meiosis I, two daughter cells are formed. During mitosis, diploid cells are formed. During meiosis 1 also, two diploid cells are formed. hence, these two processes are more similar as compared to mitosis II. in mitosis II, four haploid cells are made as a result of the division process.
Answer:
C. channel protein - allow passage of material through the hydrophilic pore
Explanation:
Channel Protein is a transport protein that has an aqueous channel throughout its transmembrane molecule, which allows the free movement of certain ions or molecules through diffusion, allowing these materials to pass through the hydrophilic pore.
From this we can conclude that the correct answer to your question is the letter C.
