Spore cell:
n= 10, c= 20
Mother cell:
2n=2×10=20
2c=2×20=40
after S -phase chromosome no. remains same but DNA content doubles
2n=20 chromosomes
4c=4×20=80 pg DNA

Texts: Hypothesis In the given time of 10 minutes: A. The 3cm cube will take in the most nutrients. B. The 1.0cm cube will absorb more nutrients than the other two sizes. C. If the three sized cells soak in vinegar for 10 minutes, then they will absorb the same amount of vinegar because they are made of the same substance and are soaking in the same vinegar solution. In general, what are the characteristics of a well-formulated hypothesis? Table 2: Vinegar (Nutrient) Diffusion Depth of Diffusion (cm) Cube Size (distance that turned clear (cm) from the video) Rate of Diffusion Time (min) (depth of diffusion/10 min) 1.0 10 2.0 10 3.0 10 Using the information above, would you say the size of the cube had an effect on the rate of diffusion? How would you determine if any differences observed were due to sampling error or the size of the cell? Table 3: Proportion of the Cube's Volume Receiving Nutrient Length Still Pink Volume of cube still pink (cm) Cube Volume (cm) Cube Size (Cube side length - pink(cm) from table 1) 2depth of diffusion Length still pink cubed Percent Volume Receiving Vinegar (see formula below) 1.0 2.0 3.0 Percent of cell receiving vinegar = (cube volume - volume still pink) * 100
