Chemical Reactions
This type of reaction always produces carbon dioxide and water.
What is combustion?
These are the first physical barriers of defence against pathogens.
What is the first line of defence?
This type of reproduction creates genetically identical offspring.
What is asexual reproduction?
The flow of electric charge is known as this.
What is current?
This state of matter has a definite volume but no definite shape.
What is a liquid?
This law explains why the total mass stays the same before and after a reaction.
What is the Law of Conservation of Mass?
These white blood cells “eat” pathogens in the second line of defence.
What are phagocytes (or macrophages)?
This term describes the joining of a sperm and egg.
What is fertilisation?
A globe in a circuit is an example of this part of a circuit.
What is a load?
The powerhouse of the cell.
What is the mitochondria?
In the reaction: Mg + 2HCl → MgCl₂ + H₂, the gas produced is this.
What is hydrogen gas?
These cells produce antibodies in the adaptive immune response.
What are B cells?
Binary fission is commonly used by these organisms.
What are bacteria?
This instrument is used to measure voltage.
What is a voltmeter?
The force that pulls objects toward Earth’s centre.
What is gravity?
This type of reaction occurs when an acid reacts with a base to form salt and water.
What is neutralisation?
These immune cells destroy virus-infected cells.
What are T cells?
This type of reproduction creates genetic variation in a population.
What is sexual reproduction?
This type of circuit has multiple branches for current.
What is a parallel circuit?
The process plants use to convert sunlight into glucose.
What is photosynthesis?
This term describes how quickly reactants are converted into products.
What is the rate of reaction?
Vaccines work by activating this line of defence, helping your body “remember” pathogens.
What is the third line of defence or adaptive immunity?
A reproductive strategy that includes a small swelling and eventually detaches off to grow as an individual species.
What is budding?
The energy lost or gained by a charge as it moves through a circuit is called this.
What is voltage (potential difference)?
This particle has a negative charge.
What is an electron?
