Chapter 2 Science &
ACTIVITY - Surface Area to Volume Ratio

Block:
Think of a cell as a cube. We are going to look at how the size of the cell affects its
efficiency. In this case, efficiency means how good the cell is at absorbing nutrients and
eliminating wastes through its cell membrane.
Surface Area (SA) of a cube = 6 x side length x side length
Volume = side length x side length x side length

Questions:
1. Which cube had a larger surface area to volume ratio, cube 1 or cube 4?
2. Which cube has the greatest surface area to volume ratio (the best efficiency)?
3. What type of cell, smaller or larger, would have a higher surface area to volume
ratio and therefore better efficiency?
4. Nine small cells have the same volume (take up the same amount of space) as a
certain large cell. Which has more cell membrane for nutrients and wastes to pass:
the one large cell or the nine smaller cells?

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a

events in order:

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
