abiotic - ANSWER pertaining to the nonliving parts of an ecosystem, such as soil particles, bedrock, air, water. abscisic acid (ABA) - ANSWER a plant hormone that stimulates stomatal closure and promotes seed and bud dormancy. abscission zone - ANSWER a wall of cells at the base of a petiole, that allows the leaf to separate from the stem. - two functions: leaf drop and to protect the region of the stem against desiccation acceptable risk - ANSWER the amount of risk that an owner is willi...

AQA A-Level Biology - Topic 3 All Answers Correct Smaller organisms have a ........... surface area to volume ratio How do single called organisms exchange substances? Higher Diffuse directly into or out of the cell across the cell surface membrane Give 2 reasons why in multicellular organisms, diffusion across outer membrane would be too slow? 1. Some cells deep within body- big distance between them and outside 2. Larger animals have low surface area to volume ratio- difficul...
