Fill in The variable that is observed and that changes in response to the independent variable is called _______________. responding variable or depending variable

The statement “the worm is 2cm long” is a(n)? Quantitative observation Qualitative observation Inference Hypothesis

An inference is? a. The same as an observation b. A logical interpretation of an observation c. A statement involving numbers d. A way to avoid bias

Measurable Observable Testable Correct To be useful in science, a hypothesis must be? Measurable Observable Testable Correct

The term ‘spontaneous generation’ means that? a. Living things can arrive from nonliving things b. Living things arise from other living things c. A maggot is part of the life cycle of a fly d. Living things evolve over time

What system is used by scientists worldwide? English system American system Metric system European system

Which of the following statements about a controlled experiment is true? All the variables must be kept the same Only one variable is tested at time Scientists always use controlled experiments Controlled experiments cannot be performed on living things

A scientific theory is: Another word for hypothesis A well-tested explanation that involves a broad range of observations The same as the conclusion of an experiment The first step in a controlled experiment

The process in which two cells from different parents unite to produce the first cell of a new organism is called: Homeostasis Development Asexual reproduction Sexual reproduction

The process by which organisms keep their internal condition relatively stable is called: Metabolism A genome Evolution Homeostasis

Convert the following unit: 3.99m = _____ km 0.03 0.0399 0.0300 0.00399

The combination of chemical reactions happening in an organism is called: Development Homeostasis Growth Metabolism

An instrument that produces images by focusing light rays is called a: Light microscope Transmission electron microscope Scanning electron microscope Electronic balance http://upload.wikimedia.org/wikipedia/commons/8/89/Evaporation.png

Explain Pasteur’s famous experiment. Pasteur’s experiment showed that boiled broth would remain free of bacteria even if air was allowed inn as long as dust and other particles were kept out.

What are 8 characteristics of living things? -made up of cell(s), reproduce (sexually or asexually), have genetic code (DNA), grow and develop, use energy, respond to the environment, maintain a stable internal environment (homeostasis), change over time (evolution).

What is goal of science? The goal of science is to investigate and understand nature, to explain events in nature, and to use those explanations to make useful predictions.

How does an observation about an object differ from an inference about that object? An observation uses senses to gather information; an inference is an interpretation based on prior knowledge and experience.

How does a hypothesis help scientists understand the natural world? Hypotheses help scientists by suggesting testable explanations for a set of observations. Hypotheses are starting points for discovering new information.

Describe three possible ways in which a hypothesis may arise. A hypothesis may arise from: Prior knowledge Logical inferences Imaginative guesses

Why is it advantageous for scientists to test only one variable at a time during an experiment? Scientists should only test only one variable at a time so that the only one observable factor affects the outcome of the experiment.

Distinguish between a variable and a control. A variable is factor in the experiment that exists in differing amount or types. A control includes those factors that remain constant (the same).

What steps are involved in making a conclusion? Scientists use data from experiments to evaluate a hypothesis and draw a conclusion that is, they use the data to support or refute the hypothesis.

Describe the impact Pasteur’s work had on the scientific community. Pasteur showed that all living things come from other living things, which was a major shift in how scientists viewed living things. He also demonstrated that infectious diseases were results of microorganisms entering the bodies of their victims.

What must happen for a hypothesis to become a theory? For a hypothesis to become a theory, it must be supported by extensive observations and many tests/experiments.

How are unicellular and multicellular organisms alike How are unicellular and multicellular organisms alike? How are they different? Unicellular and multicellular organisms are alike in that they all perform 8 life functions or characteristics. They are different in that unicellular organisms are one-celled and multicellular organisms have more than 1 cell.

Why do scientists find it helpful to use the metric system? The metric system is easy to use because it is based on multiples of 10 and is universally accepted by scientists.

How can a graph of data be more informative than a table of the same data? A graph of data can be more informative than a table because patterns of change are usually more easily seen in a graph.

What is a cell culture? How can a cell culture be useful to biologists? A cell culture is a group of cells produced when a single cell is placed in a nutrient solution and allowed to reproduce. Scientists can use cell cultures to test bacterial responses under controlled conditions and to identify bacteria.
