Which of the following is the quality of a good scientific hypothesis?

CaHeK987 [17]

Answer:

The correct answer is - option a. It should be testable in a valid period of time

Explanation:

A thought that presents a temporary clarification about a phenomenon observed by a scientist is a hypothesis. The fundamental highlights of a good scientific hypothesis are: testability and falsifiability

A testable scientific hypothesis should answer the logical question. This is one that can be checked valid or bogus utilizing the information gathered or the experience gained.

a good scientific hypothesis must be testable and falsifiable. We should have the option to test the hypothesis utilizing the techniques for science and in the event that you'll review Popper's falsifiability rule, it must be conceivable to accumulate proof that will disconfirm the theory on the off chance that it is surely false.

Thus, the correct answer is - option a. It should be testable in a valid period of time

What role does evolution play in the emergence of antibiotic resistance in bacteria?

tiny-mole [99]

1.Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

2. Bacteria evolve quickly because they grow fast and can share genes. Helpful mutations spread quickly in bacteria.

3.Taking antibiotics too often or for the wrong reasons can change bacteria so much that antibiotics don't work against them. This is called bacterial resistance or antibiotic resistance

4. Antibiotic resistance leads to higher medical costs, prolonged hospital stays, and increased mortality. The world urgently needs to change the way it prescribes and uses antibiotics.

I think so
