A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. His measurements are shown in the graph below.


Graph shows heat, measured in Joules, radiated from an aquarium over time, measured in seconds. At 0 seconds, the energy, in the form of heat, is 1.2 Joules. At 5 seconds, the energy is 1.6 Joules. At 10 seconds, the energy is 1.3 Joules. Finally at 15 seconds, the energy is 1.5 Joules.


Based on this data, he concludes that the aquarium cannot be considered a closed system for this experiment. Explain why this conclusion is invalid.


A closed system exchanges both matter and energy with its surroundings, and the scientist only measured the exchange of heat.

A closed system can exchange energy but not matter with its surroundings, and the scientist did not measure the movement of matter.

A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.

A closed system exchanges all of its matter with its surroundings, and the scientist did not measure the movement of matter.

Chieko is doing an experiment with a water clock. She fills a 2-liter soda bottle with water and marks the water level. She puts two tiny pinholes in the base of the bottle. Water seeps out. She checks the time against her watch. After an hour, she marks the new water level. She repeats this process until the water is all gone. Chieko made six hour marks on the bottle, representing the passage of six hours. How can Chieko test her water clock to see if the timing is accurate?
Group of answer choices

Repeat the experiment using a better watch

Repeat the experiment using less water in the bottle

Repeat the experiment using a kitchen timer set to go off each hour

Repeat the experiment using the same amount of water and the same watch

Which explanation justifies why the theory of evolution is a theory and not a law? (4 points) a The theory of evolution predicts an organism's ability to adapt to its environment. b The theory of evolution can be expressed as a simple mathematical statement. c The theory of evolution explains the existence of diverse forms of life on Earth. d Additional evidence will change the theory of evolution into a law.

Which of the following scenarios is an example of temporal isolation?


A.

Fossil evidence suggests that a number of members of one squirrel species evolved over time into two separate species, each on opposite sides of the Grand Canyon.


B.

Black-eyed Susans and daisies used to be part of the same species. A random mutation in a subset of a population caused one group to release their pollen three weeks before the other, causing interbreeding to cease.


C.

Two species of tree crickets live in a Costa Rican dry forest. Their habitats and ranges overlap. The two species never interbreed because the calls of the males are different and do not attract females of the other species.


D.

Indian paintbrush flowers vary greatly in color. Bumblebees form a search image for the most average common color and preferentially pollinate those flowers.
