| Using one or more of your senses to gather information is called | observing. |
| Observations that deal with a number or amount are called | quantitative observations. |
| Observations that deal with descriptions that cannot be expressed in numbers are called | qualitative observations. |
| When scientists put things into categories or group together items that are alike in some way, they are | classifying. |
| Scientists can communicate their results | at scientific meetings.,in scientific journals.,at scientific meetings. |
| A representation of an animal cell in which all of the parts are shown in the proper proportions is an example of a(n) | scale model. |
| Processes that enable an organism to survive are | functions. |
| Noticing that sugar tastes sweet is a(n) | qualitative observation. |
| During an experiment, which factors must be controlled so that researchers can draw a logical conclusion from the experiment? | variables |
| what are some branches of life science? | physiology, cell biology, plant biology |
| A species of animal develops a specialized eye structure that enables the species to see better in its environment. The big idea in life science best described by this example is that organisms | have structures and functions that are complementary. |
| In scientific inquiry, questions that are posed | can be answered through investigation. |
| At the end of a lab, you should | put your equipment away, clean your work surface, wash your hands |
| An important discovery about the interaction of grizzly bears in their environment might contribute to both | ecology and biology |
| A disturbance that transfers energy from place to place is called a | wave. |
| Mechanical waves are created when a source of energy causes a medium to | vibrate |
| A wave travels through a medium because | the wave’s energy passes from particle to particle |
| The maximum distance that the particles of a medium move from the rest position is the | amplitude of the wave. |
| The distance between two corresponding parts of a wave is the wave’s | wavelength |
| Frequency is measured in units called | hertz |
| Which waves have some electrical properties and some magnetic properties? | electromagnetic waves |
| Electromagnetic waves can transfer energy without a(n) | medium |
| What is transferred by electromagnetic waves? | electromagnetic radiation |
| The range of electromagnetic waves placed in a certain order is called the | electromagnetic spectrum |
| When a police officer uses radar for speed control, the officer is using what kind of electromagnetic waves? | gamma rays |
| Which electromagnetic waves have the longest wavelengths and lowest frequencies? | radio waves |
| Which of the following is true of ultraviolet rays? | They help your body produce vitamin D. |
| A material that reflects or absorbs any light that strikes it is | opaque |
| Frosted glass and wax paper are | translucent. |
| Clear glass, water, and air are examples of what kind of material? | transparent |
| How would a tomato look under blue light? | The tomato would appear black. |
| The primary colors of light are | red, green, and blue. |
| Colored substances that are used to color other materials are called | pigments. |
| Any two primary colors of light combined in equal amounts produce | a secondary color. |
| The bending of light rays as they enter a new medium is called | refraction |
| What happens when light passes from air into water? | The light slows down |
| When the surface of a mirror curves inward, like the inside of a bowl, it is called a | concave mirror |
| What type of image does a plane mirror produce | regular reflection |
| A flat sheet of glass with a silver-colored coating on one side is a | plane mirror |
| What instruments use lenses or mirrors to collect and focus light from distant objects? | telescopes |
