Answer:

D. Genetically distinct varieties of corn should be grown so that genetic variation will ensure at least some of the corn plants will be resistant to the corn rust.

Explanation:

Genetic diversity can be rare for selectively bred vegetable varieties, but it is the best method to use to ensure resistance to drought, pests, disease, and cold winters. Without genetic variation, one adverse condition could wipe out whole crop yields for a season.

Explain why it would not be possible to accurately measure hemoglobin concentration if the RBCs were not first lysed.
docker41 [41]

Because hemoglobin is compartmentalized inside the RBCs, lysis of RBCs is necessary for accurate measurement of hemoglobin levels.

<h3>Measure of hemoglobin concentration</h3>

Hemoglobin is a complex found in blood which is responsible for transporting oxygen to cells of the body.

Hemoglobin is composed of heme and the proteins alpha and beta globin.

Hemoglobin is found within the cytoplasm of red blood cells.

Since hemoglobin is compartmentalized inside the RBCs, lysis of RBCs is necessary for accurate measurement of hemoglobin levels.
