How many functions of life are there?
What the the Seven functions of life
Nutrition, Growth, reproduction, movement, response to stimulus, homeostasis and excretion
Micrometers to the negative 10?
Micrometers = 10^ -6 m
Nanometers to the negative 10?
Nanometers = 10^ -9 m
How would you find the magnification?
Magnification = Measured Length / Scale bar label
How would you find the actual size?
Actual size = measured length / magnification
Which is more efficient, a large or small SA:Vol ratio?
Large - as it is more efficient - diffusion pathways are shorter, molecules don't have to travel so far to enter/exit the cell (less time to transport energy), concentration gradients are easier to generate
