Both chordates and invertebrates have pharyngeal pouches
Neurotransmitters. With the regard to the process of the neural transmission, a refractory period refers to the time in interval in which. the Positively charged sodium ions are to pumped back to outside a neural membrane.
Neurotransmitters are the chemical messengers that your body can't function without it. Their job is to carry out chemical signals (“messages”) from one of the neuron (nerve cell) to the next target cell. The next target of the cell can be another nerve cell, a muscle cell or the gland.
Fortunately, the seven “small molecule” are neurotransmitters (acetylcholine, dopamine, the gamma-aminobutyric acid (GABA), or glutamate, histamine, norepinephrine, and the serotonin) do the majority of the work.

Answer:
The correct answer is -
the independent variable - if fertilizer added or not,
the dependant variable - the height of the plant and
the standardized variable - 200ml water
Explanation:
In this study, the student wanted to see the effect of the fertilizer on the growth of the plant so the independent variable is the treatment of the fertilizer as manipulated or the independent variable is the factor which is affected or changed purposely during an experiment while other variables remain constant.
The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.
The standardized or the control variable is the variable that remains constant throughout the experiment, 200 ml water treatment is the control variable in this experiment.
The protein’s function might be disrupted if the hydrogen bonds break and the protein’s structure will change due to the changes in pH or temperature.
Answer:
Explanation:The investigation is aimed at understanding
1. how molecular size affects movement through a membrane.
Therefore
2.Add more of the proteins to the plasma membrane.
Then measure the rate of the particle movement
