Answer:
True
Explanation:
Tobacco is consumed during smoking which contains an addictive substance called Nicotine. Nicotine exerts its effect on the body by stimulating the acetylcholine receptors in the neurons. The stimulation of these receptors stimulates another neurotransmitter like glutamate, dopamine and GABA which produce addictive effects in humans.
Since the acetylcholine is involved in stimulating the other neurotransmitters therefore true is the correct answer.
Thus, true is the correct answer.
Answer:
The smallest living things are single cells, and cells are the functional units of multicellular organisms.
Explanation:
Based on the information provided within the question, from the answers provided the only statement that is one or the three parts of cell theory is that the smallest living things are single cells, and cells are the functional units of multi-cellular organisms. Which although phrased differently it is explaining that all living things are made up of cells, from the smallest one celled organisms to multi-cellular organisms like us.
The other two parts of cell theory are that all living cells come from pre-existing cells by a process called cell division and that the cell is the fundamental unit of structure and function in all living organisms. Which the other answers provided do not match.
