After reading the paragraphs below, answer the questions that follow.

Many amphibians (including many frogs, toads, and salamanders) spend the early part of their lives in water but live on land as adults. The adults of many species return to water to breed and lay their eggs. Frogs have small lungs and supplement their oxygen intake by breathing through the skin. Although large frogs have more total surface area than smaller frogs, the larger frogs have a lower surface area/volume ratio (less skin surface relative to their total body volume). To keep their respiratory surfaces moist, frogs are generally found in wet or very moist locations.

In an experiment designed to investigate oxygen consumption in relation to body size, frogs from five different species were weighed and placed in a respirometer (a machine that measures oxygen consumption) for 1 hour. The table shows the results of the experiment.




From the data in the table, it is reasonable to conclude that
◦ oxygen consumption per gram of body weight is the same for all tested species.
◦ each tested species consumes a different amount of oxygen per gram of body weight.
◦ smaller frogs consume less oxygen per gram of body weight.
◦ oxygen consumption per gram of body weight for the largest species is much higher than that for the smallest species.

Did you know?

More than 30% of American adults, and about 12% of children utilize health care approaches that were developed outside of conventional medicine.

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

Did you know?

Normal urine is sterile. It contains fluids, salts, and waste products. It is free of bacteria, viruses, and fungi.

Did you know?

Cucumber slices relieve headaches by tightening blood vessels, reducing blood flow to the area, and relieving pressure.

Did you know?

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made. The mixture of cocaine, saliva, and resin numbed the site enough to allow hours of drilling.
