Kiesha wants to know what type of food wolves prefer to eat. To answer her question, she attaches a small video camera around a wolf's neck, allows the wolf to go about its normal activities for one week, and then makes notes when she later observes the video. Kirk also wants to know what type of food wolves prefer to eat. However, Kirk chooses to perform a controlled experiment. In Kirk's experiment, he keeps a wolf in captivity, offers the wolf four different selections of food each day, and records which food item the wolf selected. What is one disadvantage of Keisha's investigation?

One disadvantage of Keisha's investigation is that Keisha never find out the exact food of the wolves.

Explanation:

During Keisha's investigation, he allows the wolf to go free in order to find out their food so Keisha will never know the specific food of the wolves because in the forest there is a large variety of animals on which the wolves can feed so that's why it is a disadvantage of Keisha's investigation but keeping the wolf in the captivity just like the Kirk will allow him to find out the food preference of wolves very easily.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
