12 Φεβ 2008 · I've got a question concerning the form that should follow the verb to consider: ING or Infinitive? I've never considered being an astronaut.
6 Μαΐ 2021 · You are expected to be able to calculate the SA:V ratio for a cube, cuboid or cylinder and explain how the increasing size of an organism affects the SA:V ratio.
18 Δεκ 2016 · Cells fall within specific limits, based on the surface-area-to-volume ratio, due to specific constraints of the cell membrane and the functions of the cell itself. Plus, this section looks at how organisms manipulate cell size and shape to create various functions and complete difficult tasks!
12 Μαρ 2022 · Single-celled organisms (like amoeba) have a high SA:V ratio which allows for the exchange of substances to occur via simple diffusion. The large surface area allows for maximum absorption of nutrients and gases and secretion of waste products. The small volume means the diffusion distance to all areas is short.
31 Οκτ 2023 · As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly). Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.
26 Μαΐ 2018 · Highlights. Many bacterial species exhibit SA/V homeostasis, changing their size and shape to achieve an SA/V that is set by the ratio of surface synthesis to volume synthesis in a given growth condition.
Biology Lead. The Relationship between Surface Area: Volume Ratio & Metabolic Rate. The metabolic rate of an organism is the amount of energy expended by that organism within a given period of time. The basal metabolic rate (BMR) is the metabolic rate of an organism when at rest.
