Slide 1

Dissemination is the development of atoms from a high focus to a low fixation. Numerous particles diffuse crosswise over cell layers

Slide 2

Molecules of oxygen are spoken to by the little circles on the graph to one side. Which way will oxygen diffuse in this illustration?

Slide 3

The speed of dispersion relies on upon a few components, including temperature. Do think a higher temperature will make dissemination happen all the more quickly or all the more gradually? What is your speculation?

Slide 4

1. Fill a container or glass three fourths full with chilly faucet water. 2. Fill another measuring utencil or glass with exceptionally boiling point water. 3. In the meantime bring down a tea pack into each of measuring utencils or glasses. Try not to blend.

Slide 5

Describe the rate of dispersion in the two. Was your speculation adjust? What does this trial inform you regarding how temperature influences the rate of dispersion?

Slide 6

Osmosis is the development of water (red spots) through a semipermeable film to a higher convergence of solutes (blue dabs). Water effectively travels through cell layers by osmosis.

Slide 7

In this case there is more salt in the blood than in body cells.. Which way will water move in this case?

Slide 8

A marine fish has around 1% salt in his body. The sea water is 3.5% . Will water move into or out of the fish?

Slide 9

A freshwater angle has around 1% salt in his body. Freshwater is near 0% salt. Will water move into or out of the fish?
