What is the main difference between a hypothesis and a theory in scientific research?(1 point)

Responses

A hypothesis can never be modified, whereas a theory is subject to change with new evidence.

The correct response is:

A hypothesis is a tentative explanation that can be tested by experiments, while a theory is a well-substantiated explanation based on a body of evidence.

This highlights the distinction between the two concepts in scientific research. A hypothesis is an initial idea or prediction that can be tested, while a theory is a broader and more established explanation supported by extensive evidence.

Provide energy

The correct response is:

Provide energy

Carbohydrates are primarily used by the body as a source of energy. They are broken down into glucose, which is utilized by cells for energy to perform various functions.

Viruses are often considered non-living entities because they

have a cellular structure

can be treated with antibiotics

cannot reproduce outside of a host cell

perform metabolic processes on their own

The correct response is:

cannot reproduce outside of a host cell

Viruses are considered non-living because they lack the ability to reproduce on their own and require a host cell to replicate. They do not have a cellular structure or the capability to perform metabolic processes independently.
