The correct answer is absolute threshold.
Absolute threshold is a neurobiological term referring to the lowest level of a stimulus that a person is able to detect. The stimulus can either be touch, sound, taste or light.
Regarding taste, the absolute threshold of taste is the lowest concentration of a certain compound which can be detected by the human sense of taste.

A. Competitive inhibitor of the ligand-gated ion channel on the postsynaptic cell
Explanation:
- The competitive inhibitor of the ligand gated ion channel will exclude the true ligand from binding to the ion channel.
- The ligand gated ion channel on the postsynaptic cell will bind to the inhibitor and thus inhibiting the transfer of ion from synaptic cleft to inside of the cell.
- The nerve impulse will not be transmitted through it resulting in the paralyses.
Answer:
Independent Variable
Explanation:
The independent variable is what we are changing or what is being tested.
The control/constant group is when you do not change anything and you want to see how the object acts under normal conditions.
The dependent group is what you are measuring. (aka your data/results)
Answer:
1. Carbon dioxide
Explanation:
During photosynthesis, autotrophs such as green plants, algae, etc. remove carbon dioxide from the air and incorporate it into complex organic compounds such as glucose. Plants use much of the glucose to produce their own biomass. Heterotrophs feed on autotrophs and obtain these organic compounds from them. Heterotrophs perform cellular respiration during which oxidation of organic compounds produces ATP molecules. The process of cellular respiration returns carbon dioxide to the atmosphere. Autotrophs obtain this CO2 from the air for photosynthesis and the cycle continues.
