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.

How does the feild that surrounds the electromagnet differ from the Earths magnetic field

tino4ka555 [31]

The differences between the geomagnetism and electromagnetism are given below.

<h3><u>Explanation</u>:</h3>

Geomagnetism is defined as the magnetic field that is located all around the earth. Whereas electromagnetism is defined as the magnetic field that is produced due to passing of electricity through a conductor.

The geomagnetism is formed because of the molten elements of iron etc which are present inside Earth's core, and are continuously moving. It mostly resembles the solid block magnet in its field characteristics. But electromagnetism is different. It can be changed according to the current input which isn't possible for Earth’s magnetic field.

based on the number of ATP generated during the electron transport chain for every one glucose molecule, how many atp would be g

OleMash [197]

Answer:

If 10 glucose molecules are broken down, 320 ATP molecules will be generated during the electron transport chain.

Explanation:

In the electron transport chain, high energy electrons travel across a series of proteins embedded in the inner mitochondrial membrane, releasing energy in the process.Hydrogen is pumped from the matrix into the intermembrane space, therefore an hydrogen ion gradient is formed across the inner membrane.These proton are then pumped back into the mitochondrial membrane where the synthesis of ATP from ATP synthase takes place.

In the electron transport chain, a total of 32 ATPs are generated per glucose molecule.

so if 10 glucose molecules are broken down:

1 glucose ⇒ 32 ATPs

10 glucose ⇒ 10*32

320 ATP molecules
