SW Chapter 1 - The Science of Biology

Stimulus

• A signal to which an organism responds.

• A type of response to an external factor.

• A method of communication between organisms.

• A physical change in the environment.

What does DNA stand for?

• Deoxyribose Nucleic Acid

• Deoxyribonucleic Acid

• Dioxyribose Nucleic Acid

• Deoxyribose Nucleic Base

How do you find the total magnification of the microscope?

• Power of the eyepiece + power of the objective lens.

• Power of the eyepiece - power of the objective lens.

• Power of the eyepiece X power of the objective lens.

• Power of the eyepiece / power of the objective lens.

Asexual Reproduction

• A reproductive process that involves only one parent and produces offspring that are identical to the parent.

• A reproductive process that involves two parents and produces genetically diverse offspring.

• A process where organisms reproduce by splitting into two identical parts.

• A method of reproduction that requires external fertilization.

Controlled Experiment

• A test of the effect of a single variable by changing it while keeping all other variables the same.

• An experiment that tests multiple variables at once.

• A method of observation without manipulation of variables.

• A study that relies on historical data rather than experimental data.

Qualitative Data

• Numerical data, based on measurements.

• Descriptive data, based on characteristics.

• Data that can be counted or measured.

• Data that is represented in graphs and charts.

What characteristics do all living things share?

• Living things are made up of basic units called cells, are based on a universal genetic code, and grow and develop.

• Living things can fly and swim, and they all have fur or feathers.

• Living things are made of cells, obtain and use energy, reproduce, and respond to their environment.

• Living things are only found in water and require sunlight to survive.

Bias

• A particular preference or point of view that is personal, rather than scientific.

• An objective analysis based on empirical evidence.

• A systematic approach to problem-solving.

• A method of data collection that eliminates personal opinions.

Independent Variable

• The variable that is measured in an experiment.

• The variable that is kept constant throughout the experiment.

• The manipulated variable. This is deliberately changed (x-axis).

• The variable that is observed and recorded.

What are the characteristics of living things?

• Living things are made of cells and can fly.

• Living things reproduce and respond to their environment.

• Living things are based on a universal genetic code and can swim.

• Living things can photosynthesize and are made of rocks.
