Answer:
All errors described will result in a negative result
Explanation:
The enzyme-linked immunosorbent assay (ELISA), is a test used to detect and measure antibodies, antigens and proteins in the blood. An ELISA test uses antibodies and/or antigens that are coupled to an easily-assayed enzyme, thereby this approach combines antibody specificity with the sensitivity of simple enzyme assays. ELISA test involves an antibody or antigen that reacts to form an antigen-antibody complex, where such reaction is interpreted as a positive result. The negative results are evidenced by the lack of reaction, which may be caused by some error during the chain of reactions in the ELISA test: antigen >> primary antibody (reaction) >> functional secondary antibody (reaction) >> conjugated enzyme (reaction) >> functional substrate.
Options were missing from the question so the options are:
A.From the ice cube to the glass.
B. From the lemonade to the glass.
C. From the lemonade to the ice cube.
D. From the ice cube to the lemonade.
Answer: Option C
Explanation:
The main principle of heat transfer is that heat always flows from the hotter body to the colder body.
Here, the hotter body is thermos in which the lemonade was kept and the colder body is cooler in which the ice was kept.
During the mixing of lemonade into ice, the heat will from the hotter body to the colder body which means from lemonade to the ice. This process of heat transfer is unidirectional( hot body to cold body).
Hence, the correct answer is option C.
A.
Explanation: Because he learned it in previous years when it was different, now it becomes hard to learn the new information.
Water and nutrients make glucose
Answer: A federally funded research study involving children 8 to 12 years old involves collecting a single voided urine sample to assess the frequency of asymptomatic <em>proteinuria</em>.
Your IRB has determined that assent of children age 8 and older is required for the study. A 10 year old firmly declined to participate in the study.
The best procedure that describes the <u>action </u>to be taken by the investigator is:
- Honor the Childs decision .
Explanation:
The <em>purpose</em> of the IRB is to <em>assure that appropriate steps are taken</em> to <em>protect the rights </em>and welfare of humans participating as subjects in a research study. It promotes <em>fully informed and voluntary participation</em> by prospective subjects capable of making such choices (or, if that is not possible, informed permission given by a suitable proxy), and seeks to maximize the safety of subjects.
The capacity admits degrees. The same patient may be able to decide certain things and not others. So, the more transcendent or delicate a decision is, the higher the level of capacity required must be. When the patient <u>is not capable, it is up to his relatives to make the decisions.</u>
