at a largeAssume that you are the nurseelementary school where children frequently come toyou with nosebleeds.Design an experiment to test whether droppingkeys down the back of the neck causes nosebleeds tostop. (Assume parents of all children in the school havegiven permission for their participation in theexperiment and you have followed ethical guidelines forresearch with human subjects.One possible explanation for why keys down theback might actually be effective in stopping a nosebleedis that they are cold, causing blood vessels to constrict.Treatments should be randomly assigned to thechildren. Describe how you accomplish this.That is, when a child with a nosebleed comesto the nurse's office, how will you know whichtreatment he or she should get?

Epistaxis or nose bleeding is the bleeding from the nose.

Postural tachycardia syndrome (POTS) is a form of orthostatic intolerance, the development of symptoms that come on when standing up from a reclining position, and that may be relieved by sitting or lying back down. The primary symptom of an orthostatic intolerance is lightheadedness, fainting and an uncomfortable, rapid increase in heartbeat (tachycardia), a common response to a rapid drop in blood pressure as mediated by baroreceptors in the carotid bulb and aortic arch. There are several inconstant secondary symptoms. A syndrome is simply a constellation of symptoms, not all of which may be present in all cases, and as is the case in POTS, a syndrome may also have a wide variety of underlying causes. A subset of POTS patients suffer from a low blood volume. Would you predict that this particular subset of patients has elevated or suppressed plasma levels of renin and aldosterone? Explain your answer. The nuance of dysregulation of the RAA axis is complex in these patients,…
In what ways did the Framingham Heart Study contribute to the development of the US public health infrastructure? (Please be thorough in your response, no less than 160 words)
Which of these is the first step in using the optogenetic technique? a. Inject a radioactive chemical into the blood. b. Insert an electrode into the brain. c. Subject the brain to a strong magnetic field. d. Attach light-sensitive proteins to a virus.
The dorsal hollow nerve cord is which of the following? Question 25 options: a) A hollow tube that develops from ectoderm. Develops into the central nervous system. b) An elongation of the posterior portion of the body. Use for locomotion in fish, or balance in some terrestrial vertebrates. c) A tissue that produces thyroid type hormones. d) A flexible, rod-shaped structure that grows from mesoderm. Gives support to an animal in embryonic development of chordates or for entire life depending on the species. e) An opening in the pharynx. In aquatic chordates they allow for exit of water that enters the mouth.
Using microelectrodes, a researcher recorded nerve signals in four neurons in the brain . The neurons are called A, B, C, and D in the table below. A, B, and C all can transmit signals to D. In three experiments, the animal was stimulated in different ways. The number of nerve signals transmitted per second by each of the cells is recorded in the table. Write a short paragraph explaining the different results of the three experiment. 09

In a hypothetical experiment, a monkey was trained over 500 trials to perform well in a centre-out reaching task. The trajectory of the trained animal’s hand from the start point in the centre to each of the eight peripheral targets was tracked and is plotted in Panel A of Figure 2 below. Once the animal was trained in this task, a uniform force field was then applied to the manipulandum arm that the monkey had to move to reach the targets. The animal was trained under this new force field regimen for a further 500 trials. During one of the last trials, the force field was unexpectedly not applied. The movements in this ‘unexpected’ condition are shown in Panel D. ‘Trial’ refers to a complete set of eight movements, one to each of the targets. • Use Panels B and C to illustrate: (i) the direction of the uniform force field that must have been used in the experiment; and (ii) the trajectories of the hand that you would expect on the first of the trials carried out under the force field…
When a patient has a severe allergic reaction, a common prescribed drug is epinephrine. Which of the follow best explains the effects of epinephrine on a patient experiencing a severe allergic reaction? A epinephrine binds to the beta-1 receptor. Activating the beta-1 receptor causes vasodilation and bronchoconstriction. Bronchoconstriction allows the patient to breath by relaxing the smooth muscle that is constricting the airway. B Epinephrine binds to the beta-2 receptor. Activating the beta-2 receptor causes vasodilation and bronchodilation. Bronchodilation allows the patient to breath easier by relaxing the smooth muscle that is constricting the airway. C Epinephrine binds to the alpha-1 receptor. Activating the alpha-1 receptor causes vasodilation and bronchodilation. Bronchodilation allows the patient to breath by relaxing the smooth muscle that is constricting the airway. D Epinephrine binds to the beta-1 receptor. Activating the beta-1 receptor causes vasodilation and…
"Coarticulation" refers to the fact that in producing speech: O A. the movement of the tongue and lips must be carefully coordinated with the output of air from the lungs. B. phonemes overlap in real time, both in their production and in their sound pattern. O C.a single position of the tongue is used for several different speech sounds. D. the tongue must be moved into its appropriate position simultaneously with the positioning of the teeth and lips. Reset Selection | Mark for Review What's This? Question 6 of 45 In ordinary speech production, the boundaries between syllables or between words are usually: O A. marked by momentary pauses. B. marked by slight loudness changes. O C. marked by slight changes in pitch. D. not marked and must be determined by the perceiver. Reset Selection | Mark for Review What's This?
In the discussion section the authors wrote “The prevailing hypothesis about the action of tACS is the alternating fields can increase or decrease the power of oscillatory rhythms in the brain, and in a frequency-dependent manner, through synchronizing and desynchronizing neuronal networks [17].” a. Is the hypothesis a null hypothesis or an alternative/alternative hypothesis? b. By what word or words do you know that your answer to the question is correct? c. Why did you choose this word or words as an answer to the question?
Describe how the following changes in experimental conditions would have affected the curve obtained in the log dose-occupancy curve.
Asthma rescue inhalers are used when a person is having an asthma attack. The active ingredient is called a sympathomimetic, a substance that mimics the effects of the sympathetic nervous system. How would this help a person who is experiencing problems with breathing due to asthma? They bind to alpha receptors on blood vessels in the lungs. They bind to muscarinic receptors on airway smooth muscle.. The drug binds to beta 2 receptors on respiratory bronchiole smooth muscle. They bind to nicotinic receptors on airways in the lungs.
