A researcher conducting a study on the incidence of mutations to the MDR-1 gene in breast cancer has preliminary evidence of a l

ink between mutated MDR-1 and early recurrence. The researcher begins a new trial using prospectively collected tissue samples to further examine the link between the genetic abnormality and disease progression. He believes that he may want to re-contact some or all of the tissue donors (subjects) if the research indicates a positive link between MDR-1 mutation and early disease recurrence. What is the best procedure for an investigator planning to re-contact study subjects who provided tumor tissue for the study?

Answer:

The best procedure is to send an email, or make a call to the participants.

Explanation:

When a scientific experiment is carried out and this experiment requires human participants, it is essential that each participant provide some information such as phone number and email address. This is because during the research there may be a need to call these participants again, either to repeat a step in the experiment, to get more samples than are being tested in the experiment, or to request additional information, important for the research.

For this reason, we can say that in relation to the question above, the best way for the researcher to get in touch again with the participants of the experiment who provided tumor tissue for the study is through an email or a phone call.

andreev551 [17]

Answer:

The best answer to the question: How many trials might Jay require to perform the same task, would be: at least 30 trials.

Explanation:

Commonly speaking an intellectual disability is diagnosed when an IQ test is administered and the results show a score lower than 70. This means that a person´s perceptual, learning and understanding capacities, as well as cognition, will be less rapid than those with higher IQ scores.

Seeing a figure like a circle and a triangle, diferentiating them, learning their differences and understanding those differences, depends on the mental acuity and the fast processing and integrating centers in the brain. Jay, who has been diagnosed with an intellectual disability, which means his IQ is below 70, will take a lot more trials to differentiate a circle from a triangle, than Tony, because these shapes are particularly complex, and require the engagement of processing centers that will take longer in Jay to engage. Thus, he will need at least 10 times more tries than Tony to learn the difference between the two figures.

emmainna [20.7K]

Answer:

True

Explanation:

The idea of Vocation is central to the Christian belief that God has chosen a person specifically for a task. He has assigned a duty that he has to conform with. Hence, he is elected, trained and qualified to be the chosen person to perform that specific job.

Vocation is related to the divine call to serve humanity through lifelong commitments. It has to be followed under all circumstances to maintain the order in God's world.

Example: Adam was placed in the Eden Garden to "work it and keep it" (Genesis 2).
