Biology Leap Test

Marine biology is the study of:

• the living organisms that inhabit the sea.

• the oceans and their phenomena.

• the oceans and living organisms.

• the chemical makeup of the oceans.

• biogeochemical processes.

The following marine biologist was aboard the HMS Beagle in 1831:

• Edward Forbes.

• Charles Wyville Thomson.

• Alexander Agassiz.

• Charles Darwin.

• Jean-Baptiste Lamarck.

Charles Darwin's observations while aboard the HMS Beagle led eventually to the:

• idea that life started on land.

• theory that life's origin was in fresh water.

• theory for the process that causes evolution.

• re-birth of marine biology.

• idea that life could not survive in the deep sea.

A marine biologist observes that Mako sharks, flying fish, and salmon leap out of the water. An example of induction from these observations is:

• only some fishes can leap out of the water.

• all fishes leap out of the water.

• fishes leap out of the water to escape from predators.

• leaping out of water is often used in feeding.

• these fish must be closely related.

Which of these hypotheses CANNOT be tested by an experiment?

• Biological interactions between barnacle species are responsible for their distribution patterns.

• Night-feeding fishes rely on their sense of smell to locate prey.

• The growth of salt marsh grass is limited by nitrogen availability.

• Certain humpback whale behaviors are important for attracting a mate.

• Goldfish prefer to eat brightly-colored foods.

Ivan Valiela's hypothesis that the growth of salt marsh grass is limited by nitrogen availability was:

• disproved by the growth of larger and taller grass in his control (nitrogen-fertilized) plots.

• disproved by the growth of larger and taller grass in his experimental (nitrogen-fertilized) plots.

• supported by the growth of larger and taller grass in his experimental (nitrogen-fertilized) plots.

• supported by the growth of larger and taller grass in his control (nitrogen-fertilized) plots.

• unsupported by a poor experimental design.

Sarah remembered to use units this time, but added a second graph to distract you! Which of the Following is a piece of evidence about ENZYME A?

• The Enzyme only works at 40 degrees Celsius

• The Enzyme works best at temperatures below 20 degrees celsius

• The higher the temperatures, the faster the Reaction Rate

• Temperature directly affects the Reaction Rate of Enzyme A

What is the optimal pH and Temperature for the "Relative Rate of Enzyme Reaction"

• 53 degrees celsius and a pH of 11

• 0 degrees celsius and a pH of 4

• 37 degrees celsius and a pH of 8

• 20 degrees celsius and a pH of 6
