Each enzyme has an optimum pH at which it attains its maximum activity. That optimum pH varies for each enzyme. The optimum range for pepsin is 15-2; for stomach ligase it is 4850. In
change below or above the optimum pH range for a specific enzyme results in a decrease in enzyme action
Which graph best represents the pH and enzyme action for lipase?

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.

hello there,

guys i’m confused.
