how is that ion channels that let in positive charge could hyperpolarized a hair cell?
A. they feature unique residues that allow positive charge to go both directions
B. their ligands let out potassium ions, creating a negative electrochemical gradient
C. their ion channels are partially open at a resting state, and so closing them reduces the positive charge going into the cell
D. Ion channels that bind inverse agonist will reverse active ion transport, but only in the axon Hillock, leading to hyperpolarization down the axon
Answer:
B. their ligands let out potassium ions, creating a negative electrochemical gradient
Explanation:
A ciliated cell would be hyperpolarized by the action of positive ion kennels, when that cell received an inhibitory stimulus and the action of these channels allowed its ligands to release potassium ions (K +) and allow the entry of chlorine ions (Cl-), creating a negative electrochemical gradient, since the interior of the cell will have a negative potential greater than the external environment, which will be more positive. The result of this is to inhibit the spread of an action potential in the cellular environment.

If a nutrient does not have a Tolerable Upper Intake Level, this means that: Group of answer choices it is safe to consume in any amount. insufficient data exist to establish a value. no caution is required when consuming supplements of that nutrient. it is safe when supplemental levels are added to foods.
Answer:
The correct option is;
Insufficient data exist to establish a value
Explanation:
The upper intake level is the maximum amount of the nutrient that can be taken without the likelihood of harmful side effects on the health of an individual within the population. Taking nutrients above the stipulated upper intake level is likely to lead exposure to risk harmful side effects
Upper intake level have not been developed, however, for many nutrients due to lack adequate data as such it has been advised to apply extra caution to avoid adverse effects caused by excessive intake of such nutrients.

hair cells have a unique electrochemical gradient that, in a way, is very different from your average neuron. How so?
A. The amount of calcium is very high in the cell
B. sodium travels both directions
C. It uses GABA to depolarize it’s cilia
D. potassium is the positive charge carrier
E. sodium hyperpolarizes the cell
Answer:
A. The amount of calcium is very high in the cell
Explanation:
The electrochemical gradient of hair cells is directly related to the amount of calcium present in these cells. This is because these cells have a very high calcium concentration, causing constant leakage. These leaks are the main responsible for the release of the neutrotransmitters that will participate in the synapses.
In addition, this amount of calcium present in the hair cells is what makes these cells have an incredible speed in responding to mechanical stimuli, which makes all the difference within a biological system.

Most fad diets ________. a. produce long-lasting results b. limit food choices, which reduces energy intake c. support good health over the long term d. are balanced and do not require a dietary supplement e. embrace a variety of foods by proposing how to proportion energy nutrients
Answer:
b. limit food choices, which reduces energy intake
Explanation:
While on a fad diet you are going to have to cut certain things out like carbs, or gluten, which is limiting food choices, and we need certain foods to provide our bodies with energy, therefore by cutting out certain foods we are taking away or reducing the amount of energy that we could be recieving from the foods we are not eating.

emergency medical technicians are sometimes told to speak in the lower voice when responding to older patients, why is this?
A. lower voice sound sound more authoritative
B. The eardrums of older people are heavier and do not vibrate as well to high voices
C. conductive hearing loss typically begins in high frequency hair cells
D. lower frequencies require higher sound pressures according to the Fletcher Munson curve
E. sensorineural hearing loss typically begins in high frequency hair cells
Answer:
Option E
sensorineural hearing loss typically begins in high-frequency hair cells
Explanation:
In presbycusis, most old people cannot hear the high-frequency sounds, because of some loss of hair cells in their cochlea. unlike some other vertebrates like fishes and reptiles, these hair cells can be re-generated. However, in Humans, they cannot be.
As a result of these sounds that have higher pitches such as the buzzing of a mosquito, are muffled to them. Therefore, talking in a frequency is necessary, as this will aid the old people hear the medical technicians better.
An anxious client is admitted for treatment of an exacerbation of irritable bowel disease. The client asks the nurse if biofeedback will help after reading about biofeedback online. What is the best response by the nurse?
The available options are:
A. "Biofeedback will help reduce stress."
B. -"Biofeedback does not work for irritable bowel disease."
C. -"Stress is hard to control and you may need a medication to relax."
D. -"The device is just another expensive electronic toy."
Answer:
Biofeedback will help reduce stress.
Explanation:
This is because, research has shown that biofeedback is an evidence-based treatment for stress reduction. However, since, biofeedback is not a serious treatment, or is not indicated for the client's condition which is irritable bowel disease. Then it's expected that, the nurse should not tell the client that a medication for relaxation or biofeedback is the solution, but rather commend the client for reading and asking about the efficiency of biofeedback.
Hence, the nurse should respond that, "Biofeedback will help reduce stress."
Anxiety is defined as the feeling of fear, uneasiness, and dread, which causes sweat, an increase in heart rate, and feeling tension. The client admitted for exacerbation of irritable bowel can be given biofeedback.
The correct answer is:
Option A. Biofeedback will help reduce stress
Biofeedback can be defined as:
1. Biofeedback is a type of technique used by medical professionals in which patients are taught to control some of the body's functions. In biofeedback, the patient is connected to the electrical sensors that help in receiving information about the body.
2. Biofeedback is an evidence-based treatment for stress reduction. Biofeedback can help in reducing stress by analyzing the conditions of the disease. It is not a cure and helps in managing the conditions of the disease.
Thus, the correct answer is Option A.
