- Q1What is diffusion?active net movement of particles from an area of high concentration to an area of low concentrationpassive net movement of particles from an area of low concentration to an area of high concentrationactive net movement of particles from an area of low concentration to an area of high concentrationpassive net movement of particles from an area of high concentration to an area of low concentration60s
- Q2Which of these is NOT a factor that affects the rate of diffusion?amount of ATPconcentration gradienttemperaturemembrane surface area60s
- Q3Which of these features are NOT adaptations of villi for exchanging substances?long and thin - increases surface areaone cell thick - short diffusion pathwaygood blood supply - maintains steep concentration gradientthick muscular lining - to move the food along60s
- Q4Which of these features are NOT adaptations of lungs for efficient gas exchange?alveoli - provide large surface areamuscle tissue - to aid breathinggood blood supply - maintains a steep concentration gradientmoist membranes - increases rate of diffusion60s
- Q5Which of these features are NOT adaptations of fish gills for efficient gas exchange?large surface area for gases to diffuse acrossthin layer of cells - short diffusion pathwayscales - to prevent loss of gasesgood blood supply - maintains a steep concentration gradient60s
- Q6What is osmosis?active transport of substances from a dilute solution to a concentrated solution through a partially permeable membranediffusion of substances from a dilute solution to a concentrated solution through a partially permeable membranediffusion of substances from a dilute solution to a concentrated solution through a fully permeable membranediffusion of water from a dilute solution to a concentrated solution through a partially permeable membrane60s
- Q7Which plant cell absorbs water from the soil by osmosis?palisade cellphloem cellroot hair cellxylem cell60s
- Q8What is active transport?movement of particles against a concentration gradient - from a dilute solution to a more concentrated solution - using energy from respirationmovement of water along a concentration gradient - from a dilute solution to a more concentrated solution - using energy from respirationmovement of particles against a concentration gradient - from a concetrated solution to a more dilute solution - using energy from respirationmovement of particles along a concentration gradient - from a dilute solution to a more concentrated solution - using energy from respiration60s
- Q9Why is active transport needed in plant roots?when the plant needs more mineral ions in order to growto absorb more water when there is less water availableto absorb more mineral ions when they are in high concentration in the soilto absorb mineral ions from soil when at low concentration - against the concentration gradient60s
- Q10What is the purpose of active transport in the small intestine?to absorb more minerals when the concentration of minerals in the body is lowto absorb all the nutrients from our food during digestionto absorb more starch when the concentration of sugar in the small intestine is lower than the concentration of sugar in the bloodto absorb sugars when the concentration of sugar in the small intestine is lower than the concentration of sugar in the blood60s
