Lady bird [3.3K]

I believe its Uranus and Neptune, please tell me if I'm wrong.


Reason: an ice planet is made up of a semi icy surface like perhaps water, oxygen, or any other element stronger than hydrogen. Neptune and Uranus both meet this match, they are made up of elements that are actually stronger than hydrogen.

Which of the following statements is consistent with the principle of competitive exclusion?The random distribution of one compe
xxTIMURxx [149]

Answer:

Even a slight reproductive advantage will eventually lead to the elimination of the less well adapted of two competing species

Explanation:

The competitive exclusion describes relationship between two species that compete for the limiting sources, and cannot coexist. It is enough for one species to have slightly advantage to be dominant over the other. As a consequence, other species (the weaker one) will be extincted (shift to a different ecological niche).

What lung values changed (from those of the normal patient) in the spirogram when the patient with emphysema was selected?
Tanzania [10]

When the patient with emphysema was selected lung values changed (from those of the normal patient) in the spirogram are:

ERV, IRV, RV, FVC, FEV1, FEV1 %

<span>The reason behind the changes of these values are due to the loss or inability of electric recoil. A spirogram (graph like structure obtained by the respiratory movements) is measured by spirometer.</span>

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 :)
