A
This type of behaviour ensures species recognition before mating.
What is courtship behaviour?
Secretly mark one remaining question on the board; the next team to pick it loses 300 points (you reveal it when triggered)
This term describes organisms that can interbreed to produce fertile offspring.
What is a species?
Randomly shuffle the scores of all teams (write them on slips and redraw).
This classification system groups organisms by evolutionary relationships and common ancestry.
What is phylogenetic classification?
Triple your points if you choose a question from the hardest category next (500)
This is the highest taxonomic rank in the AQA hierarchy.
What is domain?
For the round, you automatically gain 100 points every time any team gets a question wrong.
This taxonomic level comes between family and species.
What is genus?
Your next correct answer earns double points, but your next wrong answer loses double points.
In the diversity formula, this symbol represents the number of individuals of each species.
What is n?
Pick a team that must answer their next question without speaking to each other.
This modern technique compares base sequences to clarify evolutionary links.
What is genome sequencing?
Add 1,000 points but you must answer the next question in under 5 seconds.
This ecological concept must be balanced with farming to maintain biodiversity.
What is conservation?
Swap your score with another team.
This measure counts the number of different species in a community.
What is species richness?
Pick one group to remove 100 points from
In the diversity formula, this symbol represents the total number of organisms of all species.
What is N?
Take an extra turn immediately.
This type of evidence compares proteins to determine relatedness.
What is immunological evidence?
Triple your points if you choose a question from the hardest category next.
This enzyme model suggests the active site is flexible and changes shape to fit the substrate.
What is the induced‑fit model?
Choose a team whose next turn must be answered by a team member of your choosing
In taxonomy, this word refers to a group within the classification hierarchy.
What is a taxon?
Make another team answer a question of your choosing.
This membrane component allows cells of the immune system to distinguish self from non‑self.
What are glycoproteins / antigens?
Immunity from losing points for the round
This polysaccharide in plants contains α‑glucose, 1,4 and 1,6 bonds, and is highly branched.
What is amylopectin?
Force another team to skip their next turn.
This process forces tissue fluid out of the capillaries at the arterial end.
What is ultrafiltration?
Add 500 points to your team immediately.
This taxonomic rank groups organisms that share major structural features but may differ widely in behaviour and physiology.
What is phylum?
Steal 300 points from the team with the highest score.
Removing these landscape features reduces habitats for birds and insects.
What are hedgerows?
Choose a team to halve their points.
This SPECIFIC stage of the cell cycle involves DNA replication.
What is the S phase of interphase?
If another team gets their next question wrong, you gain the points they lose.
This part of the cell surface membrane is responsible for maintaining fluidity at low temperatures.
What is cholesterol?
This feature of viruses means they cannot undergo cell division.
What is being acellular / lacking metabolic machinery?
Reverse the order of play for the next round.
This ion is a component of DNA, RNA, and ATP.
What is phosphate (PO₄³⁻)?
The next team to target you with a penalty automatically applies it to themselves instead.
This ecological process explains why fertiliser runoff reduces species richness in lakes.
What is eutrophication?
Pick a team; for the next round, whatever points they gain, you gain half.
This taxonomic rank includes organisms that share broad structural features, such as mammals.
What is class?
Choose the next category for all teams.
This term describes the narrowing of arteries due to fatty deposits.
What is atherosclerosis?
Freeze another team’s score for two rounds.
