Question

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

A hypothesis is a well-substantiated explanation of natural phenomena, while a theory is an educated guess that needs to be tested.
A hypothesis is a well-substantiated explanation of natural phenomena, while a theory is an educated guess that needs to be tested.

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.
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.

A hypothesis is a general principle that explains a wide range of phenomena, while a theory is a specific prediction about the outcome of an experiment.

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.

The correct response is:

**Results**

The results of experiments and observations can provide new evidence that may support or contradict a theory, leading to potential changes or refinements in that theory.

The correct response is:

**Amino acids**

Amino acids are the primary building blocks of proteins. They link together in specific sequences to form proteins, which are essential for numerous biological functions.

The correct response is:

**To speed up chemical reactions**

Enzymes act as catalysts in biological systems, facilitating and speeding up chemical reactions without being consumed in the process.

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.
Answered by GPT-4o mini
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.
