- Q8During exercise the water in an insect's tracheoles moves into muscle cells. What's the mechanismCohesion-tension forces, due to hydrogen bondsIncreases pressure due to air movementOsmosis due to due to decreased water potential in muscle cells, as a result of lactic acid formation.Osmosis due to due to increased water potential in muscle cells, as a result of lactic acid formation.30sEditDelete
- Q9What is the benefit of countercurrent flow in fish gills?Maintains a concentration (diffusion ) gradient across the entire width of the lamellaeAllows water movement (by osmosis) into the tissues of saltwater fishMaximises the concentration (diffusion ) gradient as water begins to flow over the lamellaeEnables water to flow with less friction30sEditDelete

- Q12What a 'xerophyte'?A plant that is adapted to dry conditionsA plant that is able to photosynthesis at high temperaturesA dispute between integers of equal but opposite magnitudeA plant, usually aquatic, that lacks stomata30sEditDelete
- Q13Why does air move out of the lungs when we exhale?Increasing volume causes decreasing pressure inside the lungs. Air moves from high to low pressure.Decreasing volume reduces the air pressure inside the lungs. Air moves from low to high pressure.Decreasing volume causes increasing pressure inside the lungs. Air moves from high to low pressure30sEditDelete
