Cells
This cell structure is known as the “control center” because it holds the cell’s DNA.
What is a Nucleus
This law explains why a soccer ball won’t move unless kicked and won’t stop rolling unless friction slows it down.
What is Newton's First Law?
This type of succession begins on bare rock where no soil exists, such as after a volcanic eruption.
What is primary succession?
This large cloud of gas and dust is the birthplace of all stars.
What is a Stellar nebula?
This term describes a trait that helps an organism survive and reproduce in its environment.
What is an adaptation?
It’s the part of the cell that controls what enters and leaves, acting like a security guard.
What is the cell membrane?
According to Newton’s Second Law, a 10-kg object accelerates at 3 m/s². This is the force acting on it.
What is 30 newtons?
This type of succession happens after a disturbance like a fire or flood, when soil is already present.
What is secondary succession?
What is the main sequence?
An example of this type of adaptation is a bear hibernating.
What is a Behavioral Adaptation
Found only in plant cells, this green organelle carries out photosynthesis.
What are chloroplasts?
A force of 50 N acts on a 5-kg cart. This is the cart’s acceleration.
What is 10 m/s²?
These organisms often lichens or mosses are the first to colonize barren environments during primary succession.
What are pioneer species?
After leaving the main sequence, an average star expands dramatically into this phase.
What is a red giant?
This type of selection causes traits that help survival to become more common in a population over many generations.
What is natural selection?
This organelle gives the plant cell its uniform shape and protects the cell.
What is a cell wall?
When you push on a cart it moves, what law is this?
What is Newton’s Third Law of Motion?
In ecological succession, this stable, long-lasting community is the final stage of development.
What is a climax community?
A massive star may end its life with a huge explosion before becoming a neutron star or black hole.
What is a supernova?
Sharp claws for hunting are an example of this type of adaptation?
What are structural adaptations?
This organelle is larger in a plant cell, but smaller in an animal cell.
What is an vacuole?
A net force of 36 N is applied to a 9-kg cart. This is the cart’s acceleration.
What is 4 m/s²?
(a = F ÷ m → 36 ÷ 9 = 4 m/s²)
After a forest fire, grasses grow first, then shrubs, then young trees.
What is Secondary succession?
This final stage of a low mass star forms when its outer layers drift away, leaving behind a dense, hot core.
What is a white dwarf?
Some frogs produce toxins in their skin that make them taste bad to predators. Over many generations, frogs that produce stronger toxins survive more often. This type of adaptation, which increases survival by deterring predators, is called this.
What is a physiological adaptation?
