Answer:

The correct answer is option D. "See which theory does a better job of explaining the results of the experiment".

Explanation:

A theory is a well established supposition that explains a phenomenon observed in nature or in laboratory based on proved principles. A scientist could compare theories by doing an experiment to see which theory does a better job of explaining the results of the experiment. This helps to see which theory is accurate and getting closer to get a definitive explanation to the observed phenomenon.

I think the answer is C, because repeating an experiment would mean the result is more accurate when done more then once. i learned this in around 7th grade, I hope it helps! (:

What molecules are made during transcription

Softa [21]

Answer:

During transcription, only one strand of DNA is usually copied. This is called the template strand, and the RNA molecules produced are single-stranded messenger RNAs (mRNAs). The DNA strand that would correspond to the mRNA is called the coding or sense strand

Which of these energy transformations is taking place in the chimpmunk when its cells use the plants sugars to carry out cell pr

Alexeev081 [22]

Answer:

This question lacks options, the options are:

A. chemical energy -> kinetic energy

B. kinetic energy -> solar energy

C. solar energy -> chemical energy

D. kinetic energy -> nuclear energy

The correct answer is A.

Explanation:

All living organisms need energy to carry out certain processes in their body. This energy is obtained in form of ATP (chemical energy) when their food molecules is broken down via a process called CELLULAR RESPIRATION.

This chemical energy (ATP) is needed to perform cellular processes in the body. According to this question, a chipmunk (animal) will utilize the energy it derives (ATP) from breaking down plant sugars to carry out its cell processes. This means that it will transform CHEMICAL ENERGY → KINETIC ENERGY.

Note that, kinetic energy is the energy due to motion in the Chipmunk.
