Why is a whale so much larger than a human?

Whales have more cells than humans

Which of the following is the best example of "form fits function" in nature?

Nonmoving (sessile) corals have long tentacles to capture food

Consider a neuron, a cell from the nervous system. What do you predict about diffusion rate at the axon section?

Diffusion will happen faster than other cell parts

Cells come in a wide variety of shapes. Many cells have extensions. What is the impact on the cell's functioning?

The extensions increase the surface area of the cells

What limits a whale's cells from being significantly larger than any other animals' cells?

As cells increase in size the rate of diffusion gets longer

Inside eukaryotic cells some organelles have sections of folded membranes. What benefit do these folds provide?

These structures increase the surface area, which improves diffusion

What was the first feature-length animated film ever released?

Snow White and the Seven Dwarfs

The blue whale is the largest known animal ever to exist. How do whale cells compare in size to human cells?

The whale cells are about the same size as human cells

Diffusion will happen faster than other cell parts
Diffusion will happen slower than other cell parts
4
Cells come in a wide variety of shapes. Many cells have extensions. What is the impact on the cell's functioning?
The extensions increase the surface area of the cells
The extensions decrease the surface area of the cells

6
What limits a whale's cells from being significantly larger than any other animals' cells?
As cells increase in size the time to achieve diffusion is unaffected
As cells increase in size the rate of diffusion gets shorter
As cells increase in size the rate of diffusion gets longer
7
Inside eukaryotic cells some organelles have sections of folded membranes. What benefit do these folds provide?
These structures increase the surface area, which improves diffusion
These structures increase the surface area, which decreases diffusion
These structures decrease surface area, which improves diffusion
These structures increase the volume, which decreases diffusion
