Answer:
Iron deficiency anemia.
Explanation:
The presence of blood in her stool does not affect blood volume, but leads to iron deficiency anemia when iron stores are depleted.
Iron deficiency anemia is a common type of anemia, a condition in which the blood does not have enough healthy red blood cells. It is due to a lack of iron, so the body cannot produce a sufficient amount of hemoglobin, a substance present in red blood cells that allows them to transport oxygen. As a consequence, iron deficiency anemia can make you feel tired and short of breath.
Alopecia areata is an autoimmune disorder that attacks the hair follicles, causing well-defined bald areas on the scalp or elsewhere on the body. It is a disorder that usually starts during childhood. It happens because the immune system would mistakenly attack the hair follicles where growth of hair starts.

Explanation:
Answer;
-Fitness
-Fitness is the contribution an individual makes to the gene pool of the next generation compared to the contributions of other individuals.
Explanation;
The genetic fitness is the reproductive success of a genotype, usually measured as the number of offspring produced by an individual that survive to reproductive age relative to the average for the population.
-It is the quantitative representation of natural and sexual selection within evolutionary biology. It can be defined either with respect to a genotype or to a phenotype in a given environment. A genotype's fitness depends on the environment in which the organism lives. The fittest genotype during an ice age, for example, is probably not the fittest genotype once the ice age is over.
