. Which of the following is used to avoid bias in a clinical trial
A) Data manipulation
B) Unfair prejudice
C) Personal interest
D) Double-blind testing

Answers

Answer 1

Answer:

D.

Explanation:

Whenever any clinical trail is conducted then the complete process is kept unbaised. Double blind testing can be defined as an experiment in which neither the researcher nor the person who is getting placebo and who is getting treatment knows. This is done in the clinical trials to keep the whole process unbaised.

A researcher is setting up a randomized clinical trial to evaluate the effect of acetaminophen on liver

function, and designates a control group of subjects and an experimental group of subjects. What could

interfere with the results or completion of this study?

Answers

Answer:

Explanation:

Ordinarily, the control group will be the group that has reduced liver function but are provided with placebo while the experimental group will be the group that has reduced liver function and are treated with acetaminophen.

Some factors that could interfere with the results of this trial are

1) Some of the volunteers could have been on some medications before the trial started, that could affect the result of the study because the medications could hamper or improve the liver function or even the performance of the drug (if it is still present in the body system).

2) Some symptomatic volunteers could be using some medications (without the researcher's knowledge) to help alleviate the pain of the reduced liver function. These medications could also affect the result as discussed in the (1) above.

3) Some volunteers could have pre-existing health conditions (that may be known or unknown to them). This could also affect the result of the research as this pre-existing health condition could render the dosage of the drug "ineffective" or even contribute to the deterioration of the liver.

One major factor that could interfere with completion of the study is the availability of patients that will consent to be used as volunteers for clinical trial. Since there are other known/effective drugs for improving liver function, it might be difficult to convince people to consent to this trial thus elongating the completion time of this study

Describe the way convection works and how it might work within the earth? -geology question

Answers

Answer:

Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.

What happens to the total blood flow during heavy exercise compared to at rest?

Answers

Blood flow is greater when you exercise because the blood vessels in your muscles dilate. Imagine water flowing through a fire hose compared to a garden hose. Adenosine triphosphate, or ATP, is the way your body uses biochemicals to store and use energy. When ATP gets used up in working muscles, the muscles themselves produce metabolic byproducts (for example, adenosine, hydrogen ions and carbon dioxide). As these byproducts leave the muscle cells, they cause small, thin-walled blood vessels (capillaries) within the muscle to expand or dilate, which is called vasodilation. The dilated capillaries allow increased blood flow, which delivers more oxygenated blood to the working muscle.

How many valence electrons does Neon have and does it have cations and anions???

1. John observed bacteria at 100X under the oil immersion and then decided to go back to 40X

objective by raising the oil objective a little to avoid the damage to objective lens. Critique his

technique. (1 pt.)

Answers

Answer:

See the answer below

Explanation:

In the first instance, the 100X objective does not have any business touching the slide on the stage so that there would not be any reason to raise it a little in order to go back to a lower objective. At higher objectives, only the fine adjustment should be used to bring the object into focus so as to avoid the objective lens from touching the slide which can damage the objective and or break the slide on the stage.

For the X100 objective to be raised in order to avoid a damage to it, it means John allowed the objective to come too close to the slide in the first place. This should not have been so.

Increased numbers of CAG repeats in the exon of a gene is associated with certain diseases. In a specific gene, the existing CAG codons are in the 'zero' reading frame, in- frame with the AUG initiation codon. The effect of increased numbers of CAG repeats on the encoded protein is:___________. a. to silence of the gene to generate a truncated protein b. to generate a protein with a run of consecutive glutamines c. to generate a frameshifted protein product d. none of the above

Answers

Answer:

The correct answer is - option b. to generate a protein with a run of consecutive glutamines.

Explanation:

The initiation code AUG is the code for methionine and as well as the initiation code for the particular protein or peptide chain. In this protein, there is a repeat of CAG is increased with the initiation code so, even though they are in zero reading frame they code for their amino acid which is glutamine.

So. an increased number of CAG repeats will result in a protein with the a run of consecutive glutamines.

Conjecture what would happen if a primate infant did not possess your chosen primate hand features. Answer this question with the survivability of the infant in mind

Answers

Answer:

Where the primate infant did not possess primate hand features, it will not be able to feed itself.  For example, a monkey cannot survive without its grasping hands.  It uses them to feed itself.  So if an infant monkey does not possess the primate hand features, its survival will be greatly hampered.

Explanation:

Ordinarily, primates (including humans) have five fingers on each of their hands and five toes on their feet.   Most primate species have fingernails instead of claws, and they have touch-sensitive pads on each of their digits. The hands and feet of all primates are designed for grasping, with the only exceptions being humans.  Human beings feature deep perceptions that differentiate them from other primates.

a. covalent bond
b. ionic bond
c. metallic bond
d. electron bond

ONLY 9

Answers

Answer:

c. metallic bond

Explanation:

Metallic bonding, unlike other forms of atomic bonding, involves delocalized elections. The negatively charged electrons form a "sea" around metal cations. Electrons within the valence shells of metals are only held loosely within their molecular orbits- the metals are held together due to the strong attraction between these delocalized electrons and positive nuclei.

The electrons are typically described as mobile, free, and delocalized. These traits are responsible for several metallic properties such as:

Explain how Karen’s science project demonstrates capillary action in the following scenario.
For her science project, Karen brought two clear glasses of water. She put a large, clear straw in one glass. Karen tried to suck up the water in the glass without the straw by hovering over the water and creating suction with her lips, but she did not touch her lips to the water. The water did not suction into her mouth. In the other glass, Karen sucked through the straw, and her audience could see the water was transported from the glass to her lips.

Answers

Answer:

Capillary action explained in the following scenario above, because if you picture the roots as the cup, the water as the water, the straw as the channels, and Karen as the plant. As Karen sucked through the straw, it was as the plant was sucking up the water through the channel from the roots. The water transported from the glass to her lips it was an example of the roots holding the water and transporting it to the plants by the channel.

Why can a planet orbit circular?

Answers

Answer:

Explanation:A circle is merely a special case of an ellipse. However, the planets do not quite move in ellipses either. The increased kinetic energy of a planet as its distance from the Sun decreases causes it to behave as though it had a greater mass, which results in the point of the orbit furthest from the Sun precessing.
