| Define biotic. | A living thing in the biosphere.
🗑
|
||||
| Define abiotic. | Abiotic is non living.
🗑
|
||||
| Put these in smallest to largest: biome, population, organism, and community. | Organism, population, community, and biome.
🗑
|
||||
| Why is biodiversity important? | It is because as soon as one extinction occurs, the genetic material is gone forever.

🗑
|
||||

🗑
|
||||
| Waves that cause the particles in a medium vibrate to both sides of the wave are called what ? | Longitudinal waves.
🗑
|
||||
| Define rarefraction. | The stretched out areas of a wave.
🗑
|
||||
| Define reflection. | Bouncing back of a wave when it hits something.
🗑
|
||||
| Define refraction. | The bending of light.
🗑
|
||||
| Waves which have particles that move perpendicular to the wave's vibrate from their resting point. | Transverse waves.
🗑
|
||||
| What is the wave height ? | The difference between a crest and an incoming trough.
🗑
|
||||
| What do you call the highest point of the wave and the lowest ? | The highest point is the wave crest and the lowest is the trough.
🗑
|
||||
| What is the wavelength ? | The distance from two equal points on the wave.
🗑
|
||||
| What kind of waves are sound waves ? | Longitudinal.
🗑
|
||||
| What kind of waves are ocean waves ? | Transverse.
🗑
|
||||
| The angle of incidence is equal to the angle of what ? | Reflection.
🗑
|
||||
| What are four things that are common to all waves ? | Wavelength, frequency, amplitude, velocity.
🗑
|
||||
| What is the waves frequency ? | # of wave crests/trough that pass a point in a given period of time after the first crest/trough.
🗑
|
||||
| What is a waves period ? | The time it takes for 1 full wavelength to pass.
🗑
|
||||
| What kind of waves can travel without a medium ? | Electromagnetic.
🗑
|
||||
| True or False: Electromagnetic waves travel at the same speed. | True.
🗑
|
||||
| Speed = what ? | frequency X wavelength.
🗑
|
||||
| What is the wave amplitude ? | It's half the wave's height.
🗑
|
||||
| What happens in cellular respiration ? | Process when mitochondria break down food molecules to produce ATP.
🗑
|
||||
| What are the 3 stages in cellular respiration? | Glycolysis, citric acid cycle, and the electron transport chain.
🗑
|
||||
| What is anaerobic ? | No oxygen is required.
🗑
|
||||
| What is aerobic ? | Requires oxygen.
🗑
|
||||
| Describe what happens in photosynthesis. | Energy from the sun stored in glucose, oxygen is given off and it produces sugar.It requires light only in presence of chlorophyll.
🗑
|
||||
| Describe what happens in cellular respiration. | Energy of glucose released and carbon dioxide is given off. Produces CO2 and H2O and it doesn't require light and occurs in all living cells.
🗑
|
||||
| Put these in largest to smallest: Infrared, visable, x-rays, gamma ray, radio waves, ultra violet. | Radio waves, infrared, visible, ultra violet, x-rays, gamma ray.
🗑
|
||||
| What does the light dependent stage do in photosynthesis ? | It traps suns energy and produces ATP without energy expense by the plant.
🗑
|
||||
| What does the light independent stage do in the photosynthesis ? | Where you put sugar.
🗑
