Step2247 [10]3 years ago
4 0

Answer:As the right ventricle contracts, the tricuspid valve closes and the pulmonary valve opens. The closure of the tricuspid valve prevents blood from backing into the right atrium and the opening of the pulmonary valve allows the blood to flow into the pulmonary artery toward the lungs.

CaHeK987 [17]

The most important issue that a researcher addresses in planning the research is the confidentiality of the individual subject's responses.

<h3>What is Research?</h3>

Research may be defined as the process of methodical examination into and investigation of materials and references in order to demonstrate attributes and acquire unexplored conclusions.

Confidentiality in research is when a researcher preserves the attributes of his subject's personal and secret and permits no one to have credentials to it.

Anonymous details are usually the most reasonable and leisurely method to glorify and brag about confidentiality in the research investigation.

The complete question is as follows:

A researcher is conducting a written survey about people's attitudes toward walking as an exercise option at the local shopping mall that supports a walking program. The survey is anonymous (without codes, names, or other information) and subjects may complete the survey and place it in a box at the shopping mall exits. Which of the following is the most important issue that the researcher addressed in planning the research?

  • Confidentiality of the individual subject's responses
  • Breach of confidentiality
  • Less predictable

Therefore, the correct option is A, i.e. Confidentiality of the individual subject's responses.

Olin [163]

Answer:

The correct answer is A. The blood vessels of the renal medulla that run alongside the nephron loops are the vasa recta.

Explanation:

In anatomy, the descending vasa recta or descending straight vessel is an artery of the renal tissue, originating from the efferent arterioles, arched artery, and interlobar artery. They are so named because they follow a straight and descending trajectory from the cortex to the deepest portions of the renal medulla.

How much Dextrose 70% must be mixed with Dextrose 5% to prepare 1,000mL of Dextrose 20%? *
erastovalidia [21]

Answer:

231 ml

Explanation:

Let x represent the amo unt of Dextrose 70% in ml and y represent the amount of Dextrose 5% in ml needed to prepare 1,000mL of Dextrose 20%.

Since 1000 ml of Dextrose 20% is needed, hence:

x + y = 1000       (1)

Also 70% Dextrose is mixed with 5% dextrose to produce 20% dextrose. i.e.:

70% of x + 5% of y = 20% of 1000

0.7x + 0.05y = 200    (2)

We have to solve equations 1 and 2 simultaneously.

Let us multiply equation 2 by 20:

14x + y = 4000        (3)

subtract equation 1 from 3:

13x = 3000

x = 231 ml

Put x = 231 in equation 1 to find y:

231 + y = 1000

y = 769 ml

Therefore 231 ml of Dextrose 70% must be mixed with 769 ml of Dextrose 5% to prepare 1,000mL of Dextrose 20%? *
