Natural selection and adaptation
He proposed the theory of evolution by natural selection in his book On the Origin of Species
Who is Charles Drew?
Genetics is the study of this?
What is how traits—like eye color, hair type, or health risks—are passed down from parents to children?
What are Reactants?
Reactants are a substance that is consumed, altered, or rearranged during a chemical reaction to form new substances called products
What is kinetic energy?
Kinetic Energy is the energy a moving object has.
A push or pull acting on an object that is not cancelled out by an opposite force, resulting in a net force that is not zero.
What is an unbalanced force?
Evolution is defined as this.
What is the change in the inherited traits of a population over successive generations?
What are genotypes?
Genotypes are the actual code or DNA you inherited from your parents (like a recipe in a book).
New substances are formed when this happens.
What is when atoms rearrange?
The name given to the form of energy that a stretched rubber band has is…
What is elastic potential energy?
What two forces are used in your daily life?
Gravity, friction, normal force, applied force, and tension
Natural selection is this process.
What is the process where organisms better adapted to their environment tend to survive and reproduce more offspring?
In pea plants, Round seeds (\(R\)) are dominant to wrinkles (\(r\)), and Yellow seeds (\(Y\)) are dominant to green (\(y\)). What is the genotype of a plant that is heterozygous for both traits?
What is RrYy?
Do you get products before or after the chemical reaction?
After
A ball sitting on top of a hill is an example of this type of energy.
What is potential energy?
Two or more opposite forces acting on an object with equal strength, resulting in a net force of zero
What is a balanced force?
On the Galápagos Islands, finches evolved specialized beak shapes based on their specific island's food source. For example, during droughts, birds with larger, stronger beaks survived because they could crack the tough seeds that remained. Is this a natural selection?
Yes it is.
If a white-furred rabbit breeds with a black-furred rabbit and all offspring have gray fur, what type of inheritance is this?
What is Incomplete dominance?
A single replacement is what type of reaction?
What is a chemical reaction
We can hear this type of energy.
What is sound energy?
Gravity pulls a falling object downward with more force than air resistance acting upwards, causing the object to accelerate, such as an apple falling from a tree. Is this an unbalanced force or a balanced force?
Unbalanced force
Goldfish have been bred for exotic shapes and colors, such as the bubble-eye or veiltail, which would not survive in the wild. Is this a natural selection?
No it is not
How many kinds of gametes are possible from an individual with the genotype \(AaBb\)?
Four types
Which atoms are in in H2O2
2 hydrogen and 2 oxygen?
How many main types of energy are there?
Ten
If an object is moving at a constant speed of 50 mph in a straight line, are the forces acting on it balanced?
Yes
