Experimental Design
If the ball is thrown over the roof then it will fall into the street and cause an accident because object cause accidents.
What is the independent variable?
Proton, neutron, electron
State of matter that has no definite shape or volume, but takes the shape and volume of their containers, filling the space available.
What is a gas?
This fills the space inside a cell. It is semi-fluid and is composed of water and dissolved materials.
Cytoplasm
Mendel used T to show the dominant allele for height, meaning tall. He used this letter to show the recessive allele.
Lowercase t
This variable stays the same throughout the whole experiment
Control or Constant
Amount of protons, neutrons, electrons in Boron
Protons 5
Neutrons 6
Electrons 5
two or more materials mixed together but not chemically combined?
What is a mixture
This organelle directs cell processes by providing DNA instructions. It is surrounded by its own membrane and is covered with pores.
What is the nucleus
Two different forms of a gene are called this.
What are alleles?
If athletes drink gatorade then their performance will increase because gatorade supplies energy to the body.
What is the dependent variable
Increase athletic performance
Amount of protons, neutrons, electrons in Copper
Protons:29
Neutrons: 35
Electrons: 29
The substance in a solution that is in the greatest amount is the ___. It is usually the liquid.
What is the Solvent
This organelle is a series of flattened membranes. Cell products pass through these membranes and become packaged for delivery in or out of the cell.
This is the probability of producing a tall pea plant from a genetic cross between two hybrid tall pea plants
what is 50%
If CJCP students study for two hours every day then their grades will increase because studying improves memory for tests
What is the Independent Variable and Dependent Variable?
Independent Variable: amount of time spent studying
Dependent Variable: Increase grades
Atoms of the same element that have different numbers of neutrons
Isotopes
Uniform mixtures are called_______________
non-uniform mixures are called ______________
homogeneous
heterogeneous
This organelle is a series of interconnected passageways. Proteins and lipids are synthesized (put together) here also.
An organism that has two identical alleles for a trait is called this.
what is homozygous?
Independent Variable: Amount of time spent practicing
Dependent Variable: Increased chance of winning a basketball game
What is the Hypothesis
If I spend more time practicing then my chances of winning basketball games will increase because practice makes perfect.
Rows of elements are called ____________. Columns of elements are called ____________.
What are periods and groups?
Identify as Element, Compound or Mixture
Air
Krypton
Ammonia
water
milk
M
E
C
C
M
This organelle is found only in animal cells. It is made of microtubules and is thought to play a role in cell division.
What are centrioles?
In Noombats, yellow bellies (Y) are dominant over green bellies (y).
Complete the Punnett square to show a cross between a purebred yellow-bellied noombat and a noombat that is a hybrid for belly color.
What is the probability that the parents will have yellow-bellied offspring?
100%
