Answer:

The correct answer is - C) pH paper + Phenol red.

Explanation:

Iodine is a reagent and indicator that is used to test confirm the presence of the starch in the sample by producing its characteristic blue-black color.

pH paper is an indicator that helps in telling about the pH level of a specific sample or solution by changing its color.

Biuret reagent is used to test for the presence of protein as it identifies peptide bonds in a solution.

Benedict's solution is an indicator that is used to confirm the presence of simple sugar in the solution or sample.

Phenol red solution is used as a pH scale to identifies the pH value of a sample or solution.

Sudan Iv is used to find the lipids and fats in the sample or solution.

Thus, the correct answer is - C) pH paper + Phenol red test for similar conditions.

Sickle-cell anemia is an example of an inherited disease. Individuals with this disorder have misshapen (sickle shaped) red bloo
Makovka662 [10]

Answer:

See the eplanation below, please.

Explanation:

In sickle cell anemia, hemoglobin has the form of rigid bars inside the red blood cells, causing them to adopt sickle shapes being not very flexible. These cells can block blood vessels, stopping the flow, causing oxygen to not reach the tissues.

The cause of this anemia is due to a genetic mutation (there is a substitution of thymine for adenine in the beta globin gene, located on chromosome 11), generating Hemoglobin S with a decrease in oxygen binding.
