When growing, as a cell gets bigger, what happens to its surface area to volume ratio?
marysya [2.9K]

<u>Answer</u>:

Surface area to volume ratio decreases.

<u>Explanation</u>:

When the cell enlarges beyond its capacity, it fails to supply enough material that can cross the membrane sooner so as to occupy the cellular volume. Hence the diffusion rate also decreases so as the ratio. The cell carry out its various functions to sustain through diffusion when diffusion rate is low it will ultimately affect the ratio. Bigger size affects the diffusion of the material to the out of the cell. as we know the diffusion occurs across the surface of the cell.

explain why a mouse (an endotherm) would probably have wider bone rings than a similarly sized lizard (an ectotherm).
____ [38]

Write in your own words:

"Since the mouse is an endotherm, it probably has a higher metabolic rate, and thus a faster growth rate, than the lizard (an ectotherm of similar size) does. If the mouse has a faster growth rate, its bones would grow more between each ring, resulting in wider bone rings."

: )

and remember that a mouse is a endotherm because it generates metabolic heat to maintain internal body temperature.

How would you calculate density for a cubic solid ?
mel-nik [20]
You are given the mass of the metal block, but you must calculate its volume using the measurements of the given dimensions. For a rectangular solid, volume = length x width x height; therefore, the volume of the block is (3 cm)(5 cm)(4 cm) or 60 cubic centimeters. The density is 14 g/60 cc or 0.23 g/cc.
