True
Changes in the transcription of mRNA or the translation of a polypeptide are not considered to be mutations because they are not permanent changes to the cell.
Explanation:
The half-life of mRNA and proteins is short. mRNA has an average of 10 hours of life span while proteins have an average of several days. Therefore mutation in these biomolecules will only persist as long as this mutated mRNA of protein exists. After its life-span, the molecule is degraded and replaced by a non-mutated mRNA or proteins. This is because the piece of DNA that codes for the mRNA and subsequent protein is not mutated. A mutation on DNA is the permanent kind of mutations because DNA is a highly stable molecule that stores information about the cell.

Carrying capacity is determined by limiting factors.
I was told that you don't need Earth Science to pass
The parts of the brain of a living organism which perform each of the functions are listed as follows:
- <u>Hypothalamus:</u> it regulates sleep.
- <u>Optic nerve:</u> it connects brain and eyes.
- <u>Cerebellum:</u> it controls balance.
- <u>The frontal lobe:</u> it controls thinking.
- <u>The </u><u>brain</u><u> stem:</u> it controls breathing and heart rate.
- <u>The nucleus accumbens:</u> it is the pleasure center.
<h3>What is a brain?</h3>
A brain can be defined as an organ of soft-nerve tissue that is found within the skull of vertebrates, and it's mainly responsible for the coordination of nervous activities, sensation and intellect in living organisms.
Based on scientific records and information, the two (2) sides of the brain (symmetrical left and right hemispheres) are able to communicate through the corpus callosum.
In conclusion, we can infer and logically deduce that the parts of the brain of a living organism which perform each of the functions are listed as follows:
- <u>Hypothalamus:</u> it regulates sleep.
- <u>Optic nerve:</u> it connects brain and eyes.
- <u>Cerebellum:</u> it controls balance.
- <u>The frontal lobe:</u> it controls thinking.
- <u>The </u><u>brain</u><u> stem:</u> it controls breathing and heart rate.
- <u>The nucleus accumbens:</u> it is the pleasure center.
