Is made of 2 or more materials physically combined; can be separated
What is a mixture?
200
The solution is Physically or chemically combined?
What is physically?
200
A process of separating parts of chemical mixtures (usually colors) dissolving them onto an absorbent material (usually paper)
What is paper chromatography?
200
What type of diversity is this?
Diversity of genes. Genetic diversity.
200
Orangutans are more closely related to gibbons or gorillas?
What is gorilla?
200
Bacteria have which type of cell, prokaryote or eukaryote?
What is a prokaryote?
300
A type of mixture that has medium-sized particles. Example: Milk
What is a colloid?
300
Two parts of a solution
Solvent - the bigger part of a solution. It is used to dissolve. example water
Solute - smaller part of a solution, it is the part the dissolves. example salt
300
Takes advantage of the physical property of the state of matter.
What is filtration?
300
A process of maintaining a stable internal condition.
What is homeostasis?
300
An older species that serves as an ______ to a more recently living species.
What are the ancestors?
300
What type of cell is this? Identify number 6.
Animal Cell
Cell membrane
400
A mixture of a gas or liquid and an insoluble substance. The insoluble substance settles to the bottom when the mixture is left to stand.
What is suspension?
400
A point in a solution in which the solvent can no longer dissolve the solute.
What is the saturation point?
400
Separating a mixture by rotating the container quickly. The heavier parts of the mixture move to the outside of the spinning container.
What is centrifuge?
400
The total sum of all chemical reactions in the body.
What is metabolism?
400
Five kingdoms of life
What are animals, plants, protists, bacteria, and fungi?
400
Give two parts that can be found in plant cells only
What are chlorophyll and cell wall?
500
A test in which the light will scatter or bounce off of particles that are large enough. This is used to distinguish between a colloid or suspension from a solution
What is Tyndall effect?
500
Compare homogeneous mixture and heterogeneous mixture.
Homogeneous mixtures have uniform composition throughout, with only one phase of matter, such as air and sugar water. Heterogeneous mixtures contain distinct regions with different properties and multiple phases, like cereal in milk and vegetable soup.
500
Compare Simple distillation and Fractional distillation
The difference between the boiling points of the fluids in the liquid mixture is less than 25-30 degrees (Fractional), and distillation has a range of boiling points of more than 25-30 degrees (Simple).

Explain the 2 ways of reproduction
Sexual Reproduction - 2 parents are required, offspring are not identical to the parents.
Asexual Reproduction - 1 parent is required, and the offspring is identical to the parents.
500
Compare Theory and Law
A theory is an idea backed up with research and experiment but the result is not the same throughout, for example, evolution theory. Law is an idea backed up with research and experiment but the result is the same throughout, for example gravitational law.
500
Explain the three parts of the cell theory,
1. Every living organism is made of one or more cells.
2. The cell is the basic unit of structure and function.
3. All cells arise from pre-existing cells. (Cells come from cells)
