"The Neuron"
Briefly describe the concept of action potential.
Answer:
The concept of action potential is a nerve impulse that begins when the inside of a neuron becomes positive enough to reach its threshold potential so that the sodium channels burst open and positive sodium ions flow into the neuron while the positive forces other positive ions, like potassium, to flow out of the neuron. The neuron then returns to its resting potential.
An action potential can be defined as the rapid rise and then the fall of the membrane potential or voltage in a pattern that is characteristic. It is a method of cell-cell communication in the body.
An Action potential has three stages - Depolarization followed by repolarization and then hyperpolarization.Depolarization is known as the rising phase during which the sodium ions (positively charged) rush out of the voltage-gated channels present in a neuron. The membrane develops a voltage of +40mV.Repolarization refers to the falling phase during which the voltage-gated sodium channels slowly close and the potassium channels open. The membrane restores the negative potential.Hyperpolarization is the last stage of an action potential during which the potassium channels remain open while the sodium channels reset.An action potential is a way of communication between the cells of the body that is carried out by the neurons.

The range and standard deviation of a distribution are _______
a. measures of central frequency
b. measures of variability
c. types of transformed scores
d. types of percentiles
Answer:
The correct answer is B) Measures of variability.
Explanation:
edg2020
The range and standard deviation of a distribution are the measures of variability. Thus, the correct option is B.
What are the range and standard deviation?Range is the difference between the highest and lowest values of the data. The range of the data is calculated by subtracting the lowest value of the data from the highest value of the data. While a large range of number means high variability, a small range of data means low variability in a distribution of data.
Standard deviation is denoted as σ. It is the measure of how dispersed the data is in relation to the mean of the data. Low standard deviation in a data means the data are clustered around the mean, and the high standard deviation indicates data are more spread out than the normal data distribution.
The range and standard deviation of a distribution are the measures of variability.
Therefore, the correct option is B.

During the first stage of the stress response
A. the body can no longer adapt.
B. the body becomes fatigued.
C.the body can perform at a higher level.
D.the hypothalamus releases a hormone.
Answer:
D. the hypothalamus releases a hormone
Explanation:
The first stage is called ¨fight or flight¨ which is triggered by the hormone released.
During the first stage of the stress response, the hypothalamus releases a hormone and the correct option is option D.
The stress response hormone is known as corticotropin-releasing hormone (CRH), which triggers the release of adrenocorticotropic hormone (ACTH) from the pituitary gland. ACTH then stimulates the adrenal glands to release stress hormones such as cortisol, which help the body respond to the stressful situation.
This initial stage is known as the alarm stage, where the body prepares for a fight-or-flight response and activates various physiological and psychological mechanisms to cope with the stressor.
Thus, the ideal selection is option D.
