Answer:
More exposure causes mutation in bacteria.
Explanation:
More exposure to the antibiotic by non-resistant bacteria causes change in its structure against the environment and as a result of that change the bacteria get resistance against that antibiotic. No, farmers should not be allowed to put low doses of antibiotics in animal feed because it has no effect on the antibiotic-resistant bacteria. The farmer should use another antibiotic on the antibiotic-resistant bacteria which they have no resistance.
Covalent bond is when two atoms share one or more pairs of electrons, an example of this could be H20 or C02.
ionic bonds are when one or more electrons from am atom are removed and attached to another, which can result in positive or negative ions which attract each other, an example of this could be table salt.
I believe this would be true
I would choose the mountain ecosystem.
The mountain ecosystem contains a complex living organisms.
Mountain lands support a diverse array of habitats with large range of plants
and animals. It is very crucial for biological diversity and is very wonderful
to see. The climate is mostly cool which is fitting for relaxation.
