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

what subject is this

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
