Intro to Biology Review

Information gathered from observing the results of an experiment is called:

• inferences

• variables

• hypothesis

• data

A scientific hypothesis must be proposed in a way that:

• ensures that the experiment will be proven true

• ensures that the experiment will work

• enables the hypothesis to be proven or disproven

• doesn't interfere with a previous hypothesis

Which of the following is not a characteristic of all living things?

• Composed of cells.

• Has the ability to move.

• Can respond to the environment.

• Can reproduce.

The stable internal environment maintained by living things is called:

• homeostasis

• differentiation

• adaptation

• interdependence

A short segment of DNA that contains instructions for the development of a single trait of an organism is known as a:

• DNA loop

• gene

• membrane

• asexual reproduction

The idea of natural selection means that:

• Organisms with certain favorable traits are more likely to survive and reproduce.

• All individuals are able to live and reproduce to the same degree.

• Individuals do not compete for resources such as food.

• Individuals evolve, but populations of organisms remain the same.

Constructing a graph is an example of which one of the following?

• Forming a hypothesis.

• Organizing data.

• Making a prediction.

• Observation.

This type of organism consists of a group of cells, but there is no relationship between the cells.

• Unicellular

• Multicellular

• Colonial

• Specialized

Plants are able to harness the energy from the sun and use it to make glucose by which of the following processes?

• Respiration

• Transpiration

• Evaporation

• Photosynthesis

The purpose of the "control" in an experiment is:

• To show the effect of the variable being tested.

• To serve as a basis of comparison because the experimental factor has been removed.

• To gather more data by repeating the experiment over and over.

• To form a conclusion based on the data gathered in the experiment.
