Most of the digestion and absorption in the small intestine is accomplished by the duodenum; the longest portion of the small intestine is the ileum.

<h3>What is Digestion and Absorption?</h3>

Digestion stands for the complex function of turning the food you eat into nutrients, which the body utilizes for energy, growth, and cell repair required to survive. The digestion process also concerns creating waste to be eliminated.

Digestion stands for the breakdown of extensive insoluble food molecules into small water-soluble food molecules so that they can be immersed in the watery blood plasma. In particular organisms, these smaller substances exist absorbed via the small intestine into the bloodstream.

Absorption exists as a physical or chemical phenomenon or a procedure in which atoms, molecules, or ions penetrate some bulk phase – liquid or solid material. This is a separate process from adsorption since molecules undergoing absorption stand taken up by the volume, not by the surface.

VladimirAG [237]

Answer: Movement along fault line

Explanation:

Here's the remainder of the question:

Which map best predicts the likely movement of land along the fault line over thousands of years?

A transform fault is simply refered to a as a fault that occurs along the plate boundary such that the motion in such case is horizontal and ends when there's a connection with another plate boundary.

Based on the question, the map that best predicts the likely movement of land along the fault line over thousands of years will be a movement along fault line.

You are operating your powerboat near a shoreline. What should you do to help prevent erosion?
soldi70 [24.7K]
If you are operating your powerboat near a shoreline, what's important for you to do if you want to help prevent erosion is maintain wake speed to avoid swerving in a counter-clockwise direction. This means that you will run the boat at the slowest possible speed if you want to avoid erosion of soil on the shoreline.

List four "beliefs" in which evolutionary scientists place their faith when supporting the theory of evolution. Use complete sen
VashaNatasha [74]

Answer:  Answers below.

Explanation: One aspect in which evolutionists place their faith in is the geological column. If you examine a chart of it, you will notice a trend. As you go deeper into the geological column, the fossils found there get more and more "simple". On the surface of the geological column, scientists have found more complex life forms. This trend suggests that organisms evolved over time, and the geological column represents this trend in chronological order. However, this data could be used against evolution as well. Therefore, it is inconclusive. If you believe the sedimentary rock formed so rapidly due to the biblical flood, this is evidence against evolution. If you believe rocks formed according to the observations of Charles Lyell, then this could be evidence for evolution. It all depends on how one interprets the data.

Another aspect in which evolutionists place their faith is something they call "intermediate links" Intermediate links are supposed to indicate a transitional form between two different creatures to show that they evolved. For example, evolutionists state that the creature Archaeopterynx is the transitional form between reptiles and birds. Another example of a transitional form found is the Australopithecus afarensis, which is supposed to be the transitional form between apes and humans due to similar bone structures and that this creature was bipedal like us humans.

Another belief evolutionists have to support the theory of evolution is the science of structural homology. Structural Homology is a science that studies similar structures in different organisms. For example, if you examined the forearms of a bat, bird, porpoise, and human, you would find that they have similar forearm structures, They all have a radius, humerus, ulna, carpals, metacarpals and phalanges. This indicates that all these creatures evolved from a common ancestor due to their strikingly similar structures.

Another aspect in which evolutionists place their faith is in the science of molecular biology. You see, all organisms contain a common protein called cytochrome C. Cytochrome c performs the same basic function in every organism. It is possible to calculate the percentage difference between the cytochrome c in each organism. Evolutionists have created a table that shows the percentage difference between a few different species of organisms. What they found appeared to indicate an evolutionary trend. However, more research shows that this data is highly flawed. If you calculate the percentage difference of this protein between a horse, pigeon, tuna, silkworm moth, wheat, the yeast and compared it to a bacterium ( the "simplest" life form) you would find that all these organisms are almost the same percent different from each other, indicating individual species rather than evolving from a common ancestor. All of these assumptions stated above can be evidence for or against evolution. It all is determined by how someone interprets these facts. I hope this helped you! Good luck :)
