IB 150 Exam Questions With Complete Solutions
10 degree Celsius rule: Correct Answers For every 10 degree
increase in temp the reaction rate doubles
5 Pre-zygotic isolation categories: Correct Answers 1. Habitat
Isolation
2. Temporal Isolation
3. Behavioral Isolation
4. Mechanical Isolation
5. Gametic Isolation
Aerobic Respiration: Correct Answers Reactions use oxygen at
the electron acceptor in the electron transport chain
Allopatric Speciation: Correct Answers When biological
populations become separated from each other and prevents
genetic interexchange
Anaerobic Respiration: Correct Answers Hydrogen donors
instead of glucose and cannot produce as much ATP
Arteries: Correct Answers Carry blood AWAY from heart with
thick walls (Moved through heart muscle contractions)
Autotrophs: Correct Answers Make their own organic matter
from inorganic nutrients and an environmental energy source
Behavioral Isolation: Correct Answers Special behaviors to
attract mates
, Capillaries: Correct Answers Site of gas exchange that has a
single cell thickness
Catalysts: Correct Answers Never created nor destroyed in
reaction- Not a reactant, simply just provides environment for
new bonds to form
Consumers: Correct Answers Herbivores (Feed on plants),
Omnivores (Both plants & animals), and Carnivores (Animals)
Counter-current Flow Correct Answers continually
maintains a favorable
concentration gradient of oxygen
between external water and
blood, leading to near 100% blood
oxygenation
Decomposers: Correct Answers Organisms that feed on dead
organic material
Ecosystem processes: Correct Answers transfer of energy and
materials
Ecosystem: Correct Answers all organisms and abiotic pools of
resources
Energy fluxes: Correct Answers consumption of organic matter
through predation or scavenging OR transfer of some of this
chemical potential energy through trophic levels of an
ecosystem
