The answer would be beta blocker.

Beta blocker is an antihypertensive drug that works by <span>decreasing norepinephrine release. The reduce of norepinephrine would prevent vasoconstriction and increased heart rate. This two effect contribute to the orthostatic hypotension the patient describe.

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 :)

When heterotrophs consume food (organic compounds), they convert it to usable chemical energy, primarily in the form of _______,
luda_lava [24]

Answer:

The correct answer is - ATP , glycolysis.

Explanation:

Heterotrophs are the organism, depends on other organisms for their food and energy. They get their energy when they take their food (glucose or other organic compound).

This organic compound is convert into the chemical energy or energy currency primarily, ATP during the process of glycolysis, the first stage or cycle of cellular respiration.

Thus, the correct answer is : ATP, glycolysis.

When does the chunk of ice have the most potential energy?
klasskru [66]

An enormous rift in one of Antarctica’s largest ice shelves grew dramatically over the past month, and a chunk nearly the size of Delaware could break away as soon as later this winter, British scientists reported this week.

If this happens, it could accelerate a further breakup of the ice shelf, essentially removing a massive cork of ice that keeps some of Antarctica’s glaciers from flowing into the ocean.
