Energy
What is kinetic energy?
Energy in motion
What is a community of living organisms interacting with their environment called?
Population
What is the basic unit of life?
The cell
Who is known as the father of evolution?
Charles Darwin
What is a wave?
Disturbance or variation that travels through a medium
How is potential energy different from kinetic energy?
One is stored and one is moving
Name one biotic factor that can affect an ecosystem.
The presence of predators
Name the process by which cells convert glucose into energy.
Cellular Respiration
What is natural selection?
Organisms adapt to their environment to survive
Name the two main types of waves.
Transverse and Longitudinal
Describe how energy is transferred during a collision.
Energy is transferred from one object to another, changing motion and can also be converted into heat or sound
Describe the role of producers in an ecosystem.
Forming the base of a food chain, converting sunlight into chemicals that can be food for plants
What are the main functions of the cell membrane?
To act as a barrier
Give an example of a trait that might be advantageous for survival in a specific environment.
Fins
Beak
Gills
Long Neck
How does the frequency of a wave relate to its energy?
at as the frequency of a wave increases, so does its energy;
What happens to energy in a closed system?
Energy is neither created or destroyed
How does energy flow through an ecosystem?
Sunlight flowing through an ecosystem
How do cells communicate with each other?
Through chemical and mechanical signals
How does natural selection lead to evolution?
favoring advantageous traits, causing organisms with those traits to survive and reproduce more successfully, thereby increasing the frequency of those traits in future generations
Explain the difference between transverse and longitudinal waves.
transverse waves have oscillations perpendicular to the wave's direction, while longitudinal waves have oscillations parallel to it.
Explain how the amplitude of a wave relates to its energy.
A larger amplitude wave carries more energy than a smaller wave
What is the significance of biodiversity in ecosystems?
Food security
Clean Water
Keeps a balance between prey and predators
What is the function of ribosomes in a cell?
Creates proteins in a cell
What evidence supports the theory of evolution through natural selection?
he fossil record, comparative anatomy, molecular biology, biogeography, and direct observation of evolutionary changes.
Describe how amplitude affects the loudness of a sound wave.
a larger amplitude means a louder sound, and a smaller amplitude means a softer sound.
