Three gel cubes similar to those from the previous
screens have been placed in a colored solution that
seeps into the gel much like nutrients enter a cell.
Use the slider to see how the solution affected the
gel cubes after some period of time.
2. How does this model support the conclusion that
cells need to have a high amount of surface area
relative to their total volume?

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.

type 2 happens when excess consumption of high-sugar foods flood the blood supply with glucose and reduce the production and effectiveness of insulin. if a person has prediabetes, they can reduce the risk of full diabetes through regular exercise and a balanced, low-sugar diet.
