AQA A-Level Biology - Topic 3 (2022/2023) with Verified Answers Smaller organisms have a ........... surface area to volume ratio Higher How do single called organisms exchange substances? 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- difficult ...

BIOS 255 Week 7 - Respiratory System Physiology Lab Report. Active cells require a constant supply of oxygen in order to produce energy to carry out cellular processes and release carbon dioxide as a waste product. The body must replenish this supply of oxygen and remove the build-up of carbon dioxide, as it is toxic to cells in high concentrations. The respiratory membrane provides a large surface area and a thin, permeable, and moist surface where the gaseous exchange of oxygen and carbon...
