The correct answer is pH 6.0.
In the given case, as the landscaper wants to plant shrubs that need a soil pH of 7.0, thus, if the pH of the soil is 6.0, then he would need to add some alkaline components to the soil.
The pH measures the accessible concentration of hydrogen ions in a solution and illustrates the comparative level of alkalinity or acidity measured on the scale of 1 to 14. The pH is logarithmic, with 14 gradations. Each elevation of 1.0 pH signifies a difference of ten times either more acidic or basic. For example, pH 6 is 10 times more acidic in comparison to pH 7.0.
Answer:
A rancher had 500 cows and took one shot that got them all.

Explanation:
When using chromatography, the 2 solutes in the solvent paper should have different Rf values from the base line to identify them as different compounds.
If they were to have the same speed in the solvent, they would appear as 1 dot instead of 2 separate dots, which is a false reading.
1. Nucleic acids are the molecules that code the genetic information of organisms.
2. The two nucleic acids used in the repair, reproduction and protein synthesis are deoxyribonucleic acid (DNA, shown) and ribonucleic acid (RNA)
3. DNA and RNA are polymers made up of monomers called nucleotides
