The answer is c: ischemia.

Explanation for each option:

a. Thrombocyte: This refers to a platelet, which is a type of blood cell involved in clotting. It does not describe a condition where blood is held back from an area.

b. Anemia: This is a condition characterized by a deficiency of red blood cells or hemoglobin, leading to a lack of oxygen in the body. It does not specifically refer to blood being held back from an area.

c. Ischemia: This is the correct answer. Ischemia refers to a restriction in blood supply to tissues, causing a shortage of oxygen and nutrients needed for cellular metabolism. It is the condition where blood is held back from an area.

d. Hematoma: This is a localized collection of blood outside of blood vessels, usually in liquid form within the tissue. It does not describe blood being held back from an area.

e. Hemolysis: This refers to the destruction of red blood cells, leading to the release of hemoglobin into the blood plasma. It does not involve blood being held back from an area.

In summary, ischemia is the term that describes the condition where blood is held back from an area.

1. Make a well-labeled diagram of your actual gel results below. The wells are indicated by the boxes. Discussion 1. The Introduction mentioned that there are three possible results when testing a given DNA sample. Each possible result is run in its own lane of an agarose gel. Describe and draw what these three lanes would look like. The three possible results represent different genotypes for a particular DNA sequence. Homozygous present indicates two copies of the allele, homozygous absent indicates no copies, and heterozygous indicates one copy of the allele. The gel electrophoresis separates the DNA fragments by size. The presence or absence of the allele affects the size of the DNA fragment and thus its migration through the gel, resulting in distinct band patterns for each genotype. It is expected that different cell types from the same patient would show the same banding pattern reflecting the same genotype. 2. Based on the expected results for the gel (NOT the actual results you sketched above), what can you conclude about the genotype of the patient in her different cell types? Explain your answer.
