Part B The image shows how different parts of a river move with different velocities. The length of the arrows represents the speed of the river. Longer arrows indicate a higher velocity than shorter arrows. a diagram showing the speed of a river at different sections of the river Based on this diagram, which parts of the river flow the fastest and which flow the slowest?

creative diagnostics provides a protocol for total protein extraction based on ripa which is widely used.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
