1. Examining the two cubes in your kit:
Table 1
Dice
Dimensions Surface Area
(cubes) (Length, width, # of sides x
and height) length x width
I
Volume
Length x width
x height
Ratio
(surface area/
volume)
Example:
Cube = 3 mm
length = 3 mm
width = 3 mm
height = 3 mm
6 sides x3 x3 =
54 mm
3x3 x3 =
27 mm
54/27 (Divide
the surface area
by the volume.
The ratio is that
number over 1.)
2/1 ratio
Small dice
5 mm
Large dice
16 mm

Which kind of aquatic ecosystem does the photograph most likely show? a. marsh b. swamp c. lake d. river

The images show the wings of a bat and a bee. from this evidence, what can you conclude about the evolutionary relationship between these organisms? a. the wing structures of the bat and the bee are different, indicating they didn’t inherit wings from a common ancestor. b. the wing structures of the bat and the bee are different, indicating they inherited wings from a common ancestor. c. the functions of bat wings and bee wings are the same, indicating they obtained wings from a common ancestor. d. the functions of bat wings and bee wings are different, indicating they didn’t obtain wings from a common ancestor.

Based on the topographic map of mt. st. helens, what is the contour interval of the volcano about height is 2,950 m?
