What is the greatest advantage of using different methods that result in the same outcome?
viva [34]

The advantages of using mixed method are, the pros and cons can be identified and compared for each method. Thus option B is correct.

<h3>What are advantages of using mixed method?</h3>

Mixed methods in research is an advanced form which is basically a combination of quantitative research and qualitative research.

It can help the researcher to gain a more clear and complete picture as it integrates benefits of both methods.

Mixed methods research is used in the behavioral, health, and social sciences, societal research.

Qualitative research has smaller sample size, so mixed methods research is applied for the comparative strength of externally valid quantitative research.

Mixing methods allowed to get findings in detail to the conclusion.

Using mixed methods from different data on same subject can give more credible results.  

Thus option B is correct.

On topographic maps, how does the spacing of contour lines relate to continental and ocean-floor topography? A. For both contine
Trava [24]

For both continental and ocean-floor topography, gentler slopes are represented by widely spaced lines while steeper slopes are represented by closely spaced lines.

Explanation:

The contour lines are one of the main, and one of the most used methods on the maps for representing the topography. Basically, the contour lines are closed lines that connect dots on the same elevation. It may sound very simple, but they do provide good insight into the topography, especially if the reader of the map knows how to interpret them well.

The contour lines are used both for continental and ocean-floor topography. The rules are the same for both, including the representation of the slopes. When a slope is gentler, the contour lines are more widely spaced. When a slope is steeper, the contour lines are much more closely spaced.

Some elements of the contour lines or that go with them to give better representation are:

  • black dots (representing a top)
  • thicker lines (every fifth, so that the counting is faster and easier)
  • small lines with given direction (representing cliffs or highly steep slopes)
  • numbers (providing information about elevation)

Which of the following substances would have the most trouble crossing a biological membrane by diffusing through the lipid bila
tangare [24]
<h3><u>Answer</u>;</h3>

d. Na+

<h3><u>Explanation</u>;</h3>
  • The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others.
  • <em><u>Small molecules that are non-polar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.</u></em>
  • Charged ions  such as N+ and K+ Cannot permeate the cell membrane for the since uncharged molecules repel uncharged molecules present in the membrane structure.
