Leya [2.2K]

The missing options of this question are:

I only

II only

III only

I, II, and III

The correct answer is "I, II, and III".

Antibiotics are of different spectrums of activity depending on the number of pathogens they can kill. They are different reasons for this differences in antibiotic specificity:

I. Antibiotics interrupt processes found in some but not all pathogen cells. For instance, some antibiotics are directed to cell walls that not all bacteria posses.

II. Some pathogens have no metabolic processes to interrupt. The antibiotics that are directed to metabolic reactions of bacteria are not effective in treating viruses because they do not perform this metabolic reactions.

III. Some pathogens have developed genetic resistance to specific antibiotics. Bacteria have a remarkable genetic plasticity having plasmids that can be easily transmitted among them, which give them antibiotic resistance.

Granite is a common type of rock found in Yosemite National Park. Limestone is a common type of rock found in Kentucky.
Elena-2011 [213]

Answer:

You should visit Kentucky.

Explanation:

Limestone is a sedimentary rock formed from the calcareous remains of dead creatures. Limestone is mostly made of shells and other remains of organisms that have collected over time. These are good conditions for fossilization. Granite, however, is an igneous rock formed from solidification of magma in the Earth's crust. High temperatures and extreme conditions make fossilization unlikely.
