Yellow Bone Marrow - ️️found in medullary cavity and in spongy bone of some bones; is yellow because it (adipose tissue) stores fat Osteocytes - ️️•mature bone cells that maintain the bone matrix •live in lacunae between layers (lamellae) of matrix •connect by cytoplasmic extensions through canaliculi in lamellae •Do not divide •Two major functions: 1. To maintain protein and mineral content of matrix 2. To help repair damaged bone Sesamoid Bones - ️️bones that are...

EXCHANGE SURFACES VERIFIED SOLUTIONS 2023/2024 Why do multicellular organisms need specialised exchange surfaces but single celled organisms don't? - ANSWER single celled organisms can exchange materials across their CSM to meet requirements - metabolic activity low → O2 needs low + CO2 produced is low - large SA:V ratio Multicellular organisms are the opposite - high metabolic rate (active + maintain temp) - small SA:V ratio 3 main features of an efficient exchange surface - ...

Why do multicellular organisms need specialised exchange surfaces but single celled organisms don't? - ANSWER single celled organisms can exchange materials across their CSM to meet requirements - metabolic activity low → O2 needs low + CO2 produced is low - large SA:V ratio Multicellular organisms are the opposite - high metabolic rate (active + maintain temp) - small SA:V ratio 3 main features of an efficient exchange surface - ANSWER • increased surface area • thin layer • ...

Metabolism - All of the chemical reactions that occur within an organism what is the need for specialised exchange surfaces? - multi-cellular organisms have a small surface area to volume ratio, they have increased metabolic rate, distance gases have to travel is further Specialised Exchange Surfaces adaptations - Increased surface area Thin gas exchange surface Good blood supply Ventilation to maintain diffusion gradient moist gas exchange surface (gases can dissolve) Explain how the al...

AQA A-Level Biology Exchange Surfaces with Questions and Answers What is the 'surface area' of an organism? ANSWER - the total surface over which substances and heat can be exchanged What is the 'volume' of an organism? ANSWER - this determines the number of substances that need to be taken in and transported out - as the volume increases, more materials are needed for metabolism because there are more cells What is the relationship between surface area and volume in an organism? A...
