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 :)

The level of which hormone increases after ovulation?
MArishka [77]

The answer should be C, progesterone.


Progesterone is the hormone which can help maintain the lining of uterus and to further thicken it so that the uterus is prepared for implantation and the development of a baby. The level of progesterone is significantly rose after ovulation.


On the other hand, LH, luteinising hormone, is produced by oestrogen, another female hormone which will drop after ovulation. LH helps stimulate ovulation and prevent the development of other follicles, the origin of eggs, to form yellow body instead. Which yellow body is the one which stimulates the production of progesterone.


Last but not least, I believe D should be testosterone, and it is a male hormone so it will not be found in female normally.


Therefore, your answer should be C, progesterone.

A pure-breeding fruit fly with curled wings mates with a pure-breeding fruit fly with normal (straight) wings. The F1 mate with
vesna_86 [32]

Answer:

The dominant curled wing allele is also a recessive lethal.

Explanation:

If we look at the F2 ratio we see that :  

curled wings: straight wings= 160:80

                                               =2:1

Hence,  if curled wings is considered to be a dominant trait then Curled wings * straight wings

Dd x dd

Punnet square will be as follows :

           d                    d

D   |    Dd   |        Dd

d    |    Dd   |        dd

Hence in order to get F2

Dd x dd

Punnet square will be the same as above if the F1 cross is Dd* Dd

        D    d

D DD Dd

d Dd dd

if DD is lethal then the ratio is

Dd:dd=2:1

that is curled wings: straight wings=2:1

Hence, The dominant curled wing allele is also a recessive lethal.
