Meerkats live together in groups to help raise and protect their offspring. Meerkat pups are most vulnerable when they are away from their burrow foraging for food. Adult meerkats exhibit sentinel behavior, standing upright and making alarm calls to warn other members in the group that predators are nearby. In a study of meerkat behaviors, scientists observed meerkat foraging groups and recorded the presence or absence of pups along with the frequency of adult sentinel behavior. The scientists determined that sentinel behavior increased when pups were present in the foraging group. Which of the following correctly identifies the dependent and independent variables in the described study? A. The frequency of sentinel behavior is the independent variable, and the presence of pups is the dependent variable. B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable. C. The number of predators is the independent variable, and the presence of pups is the dependent variable. D. The distance from the burrow is the independent variable, and the number of predators is the dependent variable.

The correct answer is - option B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable.

Explanation:

The independent variable in a study or experiment is a variable that is subject to change or manipulated to see the effect on the result of the study by influencing the dependent variable. In this study, the independent variable that is manipulated is the presence of the pups to see what is led to the behavior of meerkats.

The dependent variable is a variable that is influenced in a study by the independent variable and led to the result of the study as the frequency of sentinel behavior is influenced by the presence of the pups so the dependent variable here is the frequency of sentinel behavior.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
