Answer:
The correct answer to this question: Evaluation of evidence should be based solely upon study design:____, would be: false.
Explanation:
According to research done on the topic, there are many other issues that must be taken into account when evaluating the results of a research study, be it clinical, or in the field, and not simply study design. Study design allows the evaluators to assess the style, the form, and the way in which the study was carried out to reach results, but evaluating results, the evidence gathered only based on how the study was designed would be wrong. This evidence evaluation should focus primarily on how the intervention worked on a certain study, and whether it was carried out in such a way that would yield the proper results, without bias.
According to Boyle's law, as volume increases, the pressure of contained gases would:
a. increase
b. decrease
c. be unchanged
As volume increases, the pressure decreases since both are inversely proportional with respect to Boyle’s law.
Explanation:
An inverse proportionality exists between the volume and the pressure, this law will hold true if there are no changes in the molecules number and the temperature.
At an initial state of fixed quantity of gas, this law helps to determine changes in the pressure and volume. This law was introduced in the year 1662. According to this law, when the volume increases then the pressure in the contained gas would decrease. This is because of the reason that there exists an opposite relationship between the pressure and the volume.

Who should not take vitamin supplements?
Answer:
Children, pregnant and nursing women, people with health conditions.
Explanation:
Dietary supplement are very popular today but they are not a replacement for a balanced diet. Many supplements contain active ingredients that may be harmful to the body, especially if bought without consulting a health care provider first.
Children that eat a healthy, balanced diet don't need vitamin supplements as the food they eat contains all the nutrients they need to grow and develop properly. Pregnant and nursing women must ask their doctor before taking any kind of supplements as they can interfere with the embryo's development and even cause some birth defects, nursing women may find that some vitamins effect the quality of breast milk.
People with health conditions, awaiting a surgery or recovering from one should always take vitamins under supervision, the same applies to people taking any kind of medicine on a regular basis.

b. bones - complete skeletal system.
c. articular cartilage - covers the ends of bones at joints.
d. fibrocartilage of IVD - the annulus fibrosus of intervertebral discs
e. epiphyseal plate- in a long immature bones
Explanation:
The costal cartilages are spokes of hyaline cartilage that help to extend the ribs forward and assist in the elasticity of the walls of the thoracic cage. It is found at the anterior or front ends of the ribs.
Thus, costal cartilage - at the anterior ends of the ribs.
The human skeletal system made up of 206 bones all over the body, as well as a network of ligaments, tendons, and cartilage that connects them.
Thus, bones - complete skeletal system.
Articular cartilage covers the ends of bones where they assemble to form joints.
Thus, articular cartilage - covers the ends of bones at joints.
Fibrocartilage is A very strong tissue present in predominantly in the IVD or intervertebral disks. It attaches soft tissue-to-bone attachments.
Thus, fibrocartilage of IVD - the annulus fibrosus of intervertebral discs

Describe the mechanisms of calcium homeostasis: hormones that regulate hypo and hypercalcemia.
Answer:
The hormones involved in the calcium homeostasis are parathyroid hormone, cholecalciferol and calcitonin.
Explanation:
The maintenance of calcium level in the body is important for the proper functioning of body. The increased level of calcium is known as hypercalcemia and low level of calcium in body is known as hypocalcemia.
Hormones that regulate the level of calcium in blood are as follows:
Parathyroid hormone: The parathyroid hormone stimulate the calcium reabsorption in case of hypocalcemia. The osteoclast bone activity increases and calcium reabsorption from renal tubule, increases the calcium level of the body. This maintains calcium homeostasis in the body.
Calcitonin: An increase in the calcium ion concentration stimulates the secretion of calcitonin. The calcitonin hormone inhibits the osteoclast bone reabsorption, decreases the blood level in the body.
Cholecalciferol: This is also known as vitamin D metabolites. This hormone is stimulated in case of low calcium levels. The calcium level can be increased in the body by increasing the phosphate and calcium absorption from the gastro intestinal tract.
What is the ICD 10 code for Atrial fibrillation with rapid ventricular response
Arrange these structures in decreasing order of size:
a. sarcomere
b. fibril
c. filaments
d. fiber
Answer:
The correct answer will be Fiber → fibril → sarcomere → filaments.
Explanation:
Skeletal muscle is made up of long and cylindrical skeletal cell with a diameter up to 100 μm which are known as muscle fibres.
These muscle fibre encloses the smaller fibrils of 1.2 μm diameter which runs along the length of a muscle fiber.
Within each myofibril is enclosed the functional unit of muscle called sarcomere which is composed of contractile myofilaments- actin (thin filament) and myosin (thick filament).
Thus, Fiber → fibril → sarcomere → filaments are the correct answer.

Which of the choices below is not a factor that promotes oxygen binding to and dissociation from hemoglobin?
a. partial pressure of oxygen
b. temperature
c. partial pressure of carbon dioxide
d. number of red blood cells
The number of red blood cells does not promote oxygen binding to and dissociation from hemoglobin. Factors like the partial pressure of oxygen, temperature, and the partial pressure of carbon dioxide influence this process, but the number of red blood cells simply affects the volume of blood and its oxygen-carrying capacity.
Explanation:The factor among those listed that does not promote oxygen binding to and dissociation from hemoglobin is the number of red blood cells. Hemoglobin is a protein in red blood cells that carries oxygen. Factors like the partial pressure of oxygen, temperature, and the partial pressure of carbon dioxide influence the ability of oxygen to bind and unbind from hemoglobin because they affect the affinity, or attraction, of hemoglobin to oxygen. Meanwhile, the number of red blood cells affects the volume of blood itself and the oxygen-carrying capacity of the blood, but not the binding and dissociation process of oxygen with hemoglobin.

What is the basic defect of a disease that causes intrapulmonary shunting?
Answer:
Intrapulmonary shunting can be defined as the pathological condition which results when there is an imbalance between the perfusion of air reaching the alveoli to blood.
In other words, Intrapulmonary shunting takes place when the alveoli of lungs perfused normally with blood, but ventilation or the supply of air become unable to supply the perfused region.
Intrapulmonary shunting can result into hypoxemia in pulmonary edema and can cause pneumonia in which lungs become consolidated.

What are some examples of dishonest behaviors on the job?
Answer:
Copying the work of others, gossip, telling lies about co-workers, info sharing
Explanation:
Dishonest behaviors on the job can be seen in many different forms. The most common one is copying or even stealing the work of others and passing it on as one's own. It is not only dishonest, it breaks the trust between co-workers and may be considered theft and a reason to be fired. Spreading gossip, telling others facts about a person's personal life or simply inventing things to make somebody be seen in a bad light, all these are also dishonorable, dishonest behaviors. Complaining about a person's behavior to the boss without confronting the person in question first can be another example of it. Selling confidential, internal information to a rival company is one of the biggest dishonest behaviors ever, as it goes completely against the company's trust policy.
Define and differentiate Central nervous system vs peripheral nervous system
Answer:
Central nervous system is comprised of brain and spinal cord. Various sorts of sensory information are integrated and correlated within the central nervous system. In central nervous system, thoughts and emotions are generated and memories our farm and stored.
Peripheral nervous system is comprised of cranial nerves that are arising from the brain and the spinal nerves that are arising from the spinal cord
Explanation:
The central nervous system consists of the brain and spinal cord, controlling most functions of the body and mind, while the peripheral nervous system is the network that sends signals between the central nervous system and the limbs and organs, essentially enabling communication with the rest of the body.
Explanation:Central Nervous System (CNS) vs. Peripheral Nervous System (PNS)
The central nervous system (CNS) comprises the brain and spinal cord, serving as the control center for processing information and directing responses. Enclosed within the cranial and vertebral cavities, the CNS functions as the power plant, orchestrating complex neural functions and overall bodily coordination.
The peripheral nervous system (PNS), in contrast, acts as the wiring that connects the CNS to the muscles, organs, and senses spread throughout the body. It includes thick bundles of axons called nerves, carrying messages to and from the CNS. The PNS is further divided into the somatic nervous system, which manages voluntary movements, and the autonomic nervous system, controlling involuntary actions.
Sympathetic stimulation causes:
A. relaxation of the bronchial smooth muscie
B. increases resistance to air flow
C. decreased the diameter of airways
D. release of HCO3 from goblet cells
E. release of renin from macula densa
During an asthma attack the:
a. all of these answers and correct
b. Bronchiole smooth muscle contracts which reduces the diameter of the airways
c. Alveoli collapse and air no longer travels into them
d. Bronchioles dilate resulting in not enough air pressure in the air passageway
Answer:
The correct option is : b. Bronchiole smooth muscle contracts which reduces the diameter of the airways
Explanation:
Asthma is an incurable inflammatory disease which affects the airways that carry the oxygen in and out of the lungs. It can be caused by various genetic and environmental factors. Asthma is characterized by breath shortness, coughing, chest tightness and wheezing.
It is caused due to the inflammation of the passage that conducts air into the lungs, especially the bronchi and the bronchioles. Asthma does not affect the alveoli. The inflammation of the bronchioles causes the contraction of the smooth muscles and results in narrowing of the airways. Therefore, causing wheezing.
During an asthma attack, the bronchiole smooth muscle contracts, reducing the diameter of the airways which causes symptoms such as shortness of breath. The Alveoli don't collapse, rather air gets trapped in them due to the bronchioles' inflammation and contraction.
Explanation:During an asthma attack, the answer, b. Bronchiole smooth muscle contracts which reduces the diameter of the airways, is accurate. Asthma is a chronic upper respiratory condition where the bronchioles, or small airways in the lungs, overreact to certain stimuli such as allergens or exercise. The walls of the bronchioles contain smooth muscles which, when they contract due to an asthma attack, reduce the diameter of the airways.
This causes shortness of breath, coughing, and wheezing. Answer c. alveoli collapse and air no longer travels into them, is incorrect because in asthma, the alveoli don't collapse but rather air gets trapped in them due to the contraction and inflammation of the bronchioles. Answer d. bronchioles dilate resulting in not enough air pressure, is also incorrect. In fact, bronchodilation, or opening of the airways, is what medicines for asthma aim to achieve.

Syphilis can only be spread during stages one and two.
a) True b) False
Answer:
The correct answer to the question: Syphilis can only be spread during stages 1 and 2, would be: false.
Explanation:
Syphilis is a sexually transmittable disease caused by a bacteria. I can only be gotten through sexual activity, or contact with the body fluids or lessions of someone infected, but in order for this contagion to be possible, the person must either be in the initial, or stage 1 of the infection, stage 2 of the infection, or if they are in a stage called the latent stage. This latter, the latent stage, is usually the more dangerous because people don´t tend to show signs, or symptoms of it, which does not mean that the infection is not there. So, in general, there would be really three, out of the four, stages, during which syphilis can be spread to others, and not just the two initial ones. This is why the statement is false.
