Answer:

The answer is C - Theories are supported with evidence and do explain what we see in the world (Ex: The cell theory) The evidence can change or be added on to when new evidence is found.

Explanation:

A - Theories are not hypotheses but theories start out as hypotheses. When the hypotheses gain enough evidence, they can start to become a theory, and this is after many experimentations and testings and trials and research.

B - Everyone can have theories, not just scientists. Many theories have been made on social media platforms such as r e d d i t or y o u t u b e. Some of these theories are conspiracy theories that people make based on some evidence they gather about a topic and sometimes believe is true even though it may not be true.

D - Theories are not opinions but are backed up with evidence and may have went through many trials and errors to become where it is.

E - Theories are testable ideas and scientists are always trying to make theories to be the best of what it can be. Theories have to be tested over and over again to make sure that whatever the theory is about is still valid and works.

Clear cutting has a similar effect as controlled burning of a forest. True False
zysi [14]

The correct answer is false and here is why:

Clear cutting refers to the cutting of trees, specifically all of the trees in one select area. Replanting is not done and this leads to deforestation.

Controlled burns have a completely different affect. They burn the under brush to help keep the soil rich with nutrients, plus they also help to prevent large crown fires that burn down whole forests from happening.

Clear cutting is a bad thing and controlled burns are a good limiter for a forest.

Which description is true for both DNA and RNA molecules
GrogVix [38]

The correct answer is A.

Both DNA and RNA are types of nucleic acids.  DNA stands for deoxyribonucleic acid , while RNA stands for ribonucleic acid.

Both DNA and RNA carry genetic information. However,  DNA is chiefly responsible for storing and transferring genetic information whereas RNA acts as a messenger between DNA and ribosomes during the process of protein synthesis and directly codes for amino acids.

DNA is double stranded while RNA is single stranded.

DNA has thymine in its structure but RNA does not. Instead in place of thymine it has uracil.
