Electric Circuits
This is the flow of electric charge through a conductor.
What is current?
When a chemical reaction occurs, these are formed.
What are products?
The basic unit of heredity that carries genetic information.
What is a gene?
Energy cannot be created or destroyed — only changed in form. This is known as this law.
What is the Law of Conservation of Energy?
This type of circuit allows electricity to take more than one path.
What is a parallel circuit?
This component opposes the flow of current in a circuit.
What is a resistor?
A reaction that releases energy in the form of heat is called this.
What is an exothermic reaction?
This molecule has a double-helix structure and carries genetic instructions.
What is DNA?
The energy stored in an object due to its position or height is called this.
What is gravitational potential energy?
When magnesium reacts with hydrochloric acid, this gas is produced.
What is hydrogen gas?
The formula V = I × R represents this law.
What is Ohm’s Law?
The Law of Conservation of Mass states that this is always the same before and after a reaction.
What is the total mass?
A Punnett square is used to predict these.
What are possible offspring genotypes or traits?
When a ball falls, its potential energy is transformed into this type of energy.
What is kinetic energy?
In genetics, the physical expression of a gene — such as eye colour or blood type — is called this.
What is a phenotype?
In a series circuit, if one component fails, this happens to the rest of the circuit.
What is the entire circuit stops working?
When a metal reacts with oxygen, this type of compound forms.
What is a metal oxide?
When both alleles in a pair are the same, the genotype is described as this.
What is homozygous?
This term describes how effectively energy is converted into useful work.
What is energy efficiency?
A roller coaster at the top of a hill has maximum potential energy. As it descends, that energy transforms into this form.
What is kinetic energy?
In a parallel circuit, adding more branches causes the total resistance to do this.
What is decrease?
The reaction between an acid and a base produces these two substances.
What are salt and water?
This process during meiosis increases genetic variation by exchanging genetic material between chromosomes.
What is crossing over?
In a light bulb, only a small portion of electrical energy becomes light. The rest is transformed into this.
What is heat energy?
In a chemical reaction, if energy is absorbed from the surroundings, the reaction is described as this type.
What is an endothermic reaction?
