worty [1.4K]

Answer:

The idea model is used to for relationships between variables, such as time and distance, that can be graphed or be placed into an equation. A physical model, on the other hand, is generally used for objects, such as a cell, to show the various parts and their orientation in respect to each other. A computer model is used to track weather patterns and other factors to predict natural events.

What is the TECTONIC CYCLE? Briefly summarize it.
igomit [66]
<span>In simple terms, heavier plates get melted in Mantle, become lighter in form of lava and create new plates. As we have a re-cycle or the convection currents, there are cycles in lithosphere.
There is continuous push and pull happening on and below the Earth. When a plate is subducting on one end, there has to be some reaction on the other end, right?
Ridge is developed on the other side, where the same material which has been melted on the subduction side helps to fill the gap at ridge side. Since the material is just transfered from heavy to light, and reused in that cell, it is called a cycle.

Cellulose is another long polymer of glucose. Plant cells make their cell walls out of cellulose. In fact, 100 billion tons of cellulose is made every year on earth. Cellulose is indigestible in most animals, including us. Ever eat a cardboard box? You get the picture. We simply lack cellulase, the enzyme that can break it down. Some bacteria, some single-celled protists, and fungi have the enzyme. Animals that feed on cellulose harbor these microbes that help them digest it. Even though, we cannot break down this molecule, we do need cellulose in our diet. We call it “fiber”. Cellulose stimulates the colon to produce regular bowel movements and helps make the stools large and soft. A diet rich in fiber can prevent a painful intestinal disorder called diverticulosis. Hard impacted stools can sometimes cause the walls of the colon to form blind outpockets called diverticula which can periodically inflame. So what makes cellulose different from starch? Isn’t it made of glucose? Well it is but the glucose monomers are organized in an interesting fashion. The orientation of the glucose molecules alternates. So if the first one is right side up, the next one is upside down and then the next is right side up and the next one is upside down. Apparently this is a tricky arrangement for an enzyme to break.
