A client takes a home pregnancy test. While she is waiting to read the results, her phone rings. When she gets off the phone 15
Contact [7]

Answer:

Yes a false positive result will be read

Explanation:

Instructions on most pregnancy tests will tell you to read the results in a certain amount of time, usually from a couple of minutes. So you may take a pregnancy test and read it within the above time period as negative.

If you happen to keep the test around to look at later, you may notice that after that allotted time, the test now appears to have a positive result. This is called an evaporation line. It is not indicative of a positive pregnancy test.

What is Evaporation Lines?

Evaporation lines happen when the urine that was on the test area starts to dry out and evaporate. The chemical composition of that particular urine sample has now changed since that urine sample evaporated, sometimes causing the test to show a positive line

What is cell surface to volume ratio and why is it important in cell functioning? Can it explain why cells are so small?
MrMuchimi
<span>The main reason surface area to volume ratio is important to a cell is because the surface area to volume ratio determines the rate at which cells uptake nutrients, liquids or gases. For instance, I have two organisms, A and B. Organism A has a surface area to volume ratio of 6:1, whereas organism B has a surface area to volume ratio of 3:1. As organism A has a greater surface area to volume ratio, it means that organism A will be able to take up nutrients, liquids or gases via diffusion or osmosis at a greater rate than organism B, as it has more surface with which to exchange nutrients, liquids or gases. </span>
