A federally funded research study involving children 8 to 12 years old involves collecting a single voided urine sample to asses
777dan777 [17]

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>

How does the temperature affect enzyme function? use evidence from your data to support your answer?
ololo11 [35]
If the temperature is too high, it can alter the structure of the enzyme and make it unable to bind to the substrate. But, if the temperature is too low the chance for the enzyme to collide with the substrate will be lower too. The enzyme works best in the highest temperature before its structure changed.
The data from the experiment should look like a bell. There is an optimal temperature for the enzyme and increasing/decreasing from that temperature will result in reduced reaction speed.

An atom with 9 protons and 8 electrons is what kind of atom?
Reika [66]

Answer:

B. A cation

Explanation:

An atom is the smallest indivisible component of a matter including an element. An atom contains three particles called SUBATOMIC PARTICLES (PROTON AND NEITRON in the nucleus and ELECTRON surrounding the nucleus). The proton is positively charged while the electron is negatively charged.

The number of protons and electrons determine whether an atom will be postively charged (cation) or negatively charged (anion). In this question, an atom with 9 protons and 8 electrons will be A CATION because the protons (9) are more than the electrons (8), hence, making it a positively charged atom (cation).

N.B: The cation atom will have a +1 charge
