The right answer is common error.
A common error (or random error) is when, from one measure to another, the value obtained may be overvalued or underestimated in relation to the real value.
An example of a random error is the measurement of time with a timer. The error comes from the reaction time of the experimenter at start-up and at the end of the timer. Since this reaction time is not always the same, the measured value can be overestimated or underestimated. It is understandable that a repetition of the measures can alleviate the random error.
<h2>Competitive inhibitor </h2>
Explanation:
Competitive inhibitor is the one which binds to the active site on the enzyme, blocking substrate molecules from the site
- Competitive inhibitor is a type of reversible inhibitor in which inhibitor binds with enzyme's active site hence inhibitor competes with substrate for binding site
- The activity of competitive inhibitor is overcome by increasing substrate concentration
- In competitive inhibition,the value of Km(Michaelis Menten constant) increases whereas that of Vmax(maximum velocity) remains unchanged
Answer;
B. It arouses the body and expends energy.
Explanation;
-The autonomic nervous system controls the insides of the body: the viscera or gut. It carries information about the inside of the body to the CNS and controls the action of internal organs. The autonomic nervous system has two divisions: the sympathetic division and the parasympathetic division.
-The sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. The parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
Answer: The neurotransmitter molecules then diffuse across the synaptic cleft where they can bind with receptor sites on the postsynaptic ending to influence the electrical response in the postsynaptic neuron.
I hope this helps you:)
