Chapter 8
the process in which plants use energy from light to produce sugar
What is photosynthesis?
The flexible rod-shaped structure that supports the body of a developing chordate
What is a notochord?
The center of an atom
What is the nucleus?
energy due to motion
What is kinetic energy?
is a disturbance that transfers energy from place to place
What is a wave?
Moss plants are held in place by root-like, threadlike structures
What are rhizoids?
organisms with many cells
What is multicellular?
____ is another name for a homogeneous mixture
What is a solution?
the resistance that one surface or object encounters when moving over another
What is friction?
The release of electricity stored in a source
What is electric discharge?
the process in which organisms break down food to release ATP energy
What is cellular respiration?
Most invertebrates have a hydrostatic skeleton or a(n) ________________.
What is an exoskeleton?
the 2 ways to classify matter
What are substances and mixtures?
The number of complete waves that pass a given point in a certain amount of time.
What is frequency?
Waves in which the particles move perpendicular to the direction of wave motion
What are transverse waves?
the name of the small openings on leaves that allow gases to move in or out during photosynthesis and cellular respiration
What is stomata?
Name the 3 types of body plans animals have and name an animal with each type.
Asymmetry-sponges, bilateral symmetry-alligator, radial symmetry-jellyfish
the number of protons each element has
What is atomic number?
Types of waves on the electromagnetic spectrum.
What are radio waves, microwaves, infrared waves, light waves, UV waves, X ray waves, and gamma waves?
A material in which electrons can easily move with low electric resistance; examples: copper and aluminum
What is an electric conductor?
Compare and contrast gymnosperms and angiosperms.
They both produce seeds, but gymnosperms produce cones and angiosperms produce fruit and flowers.
Explain the difference between vertebrates and invertebrates and give examples of each.
Vertebrates have a backbone, but invertebrates do not. Vertebrate examples: humans, birds, and fish
Invertebrate examples: jellyfish, worms, and snails
Differentiate between heterogenous and homogenous mixtures and give examples of each.
Heterogenous mixtures do not mix evenly so you can easily separate them and you can easily tell the substances apart. But homogenous mixtures do mix evenly so you can't tell the substances apart and they're hard to separate. Examples-
Heterogenous mixture: trail mix or gumbo. Homogeneous mixture: salt water kool-aid
highest part of a transverse wave
What is a crest?
Compare and contrast light waves and sound waves.
Both types of waves transfer energy and travel through matter. However, light waves travel faster than sound waves and light waves are transverse and electromagnetic, while sound waves are longitudinal and mechanical.
