A Nurse knows that type 1
diabetes mellitus (DM type 1) occurs as a result of destruction of the
pancreatic beta cells. This destruction can occur by two mechanisms. The
mechanism for DM type 1A is AUTOIMMUNE destruction, while the mechanism for DM
type 1B is idiopathic destruction.
Answer:
Luzon Island, in the Philippines has the greatest number of unique animal species.
Explanation:
Researchers have shown that out of 56 species of non-flying mammal species that are now known to live on the island, 52 live nowhere else in the world. Of those 56 species, 28 were discovered during the course of the project. Nineteen of the species have been formally described in scientific journals, and nine are currently “in the works.” Currently 93% of the island's land land mammals have been found no where else.
Answer:
Membrane-Bound Organelles
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.
