There are amphibians that are even larger than bullfrogs. Which of the following could explain how such a large amphibium could

obtain a sufficient rate of diffusion of respiratory gases? Select all that apply: Select one or more: a. different shape (e.g. flat or ribbon shaped) b. dry skin c. reduced metabolic rate (reduced rate of cellular respiration) d. larger internal surface area of the lungs e. living in an environment of lower oxygen concentration

Answer:

a. different shape (e.g. flat or ribbon shaped).

d. larger internal surface area of the lungs.

Explanation:

Amphibians are cold blooded animals. They have a low rate of metabolism . Amphibians are located most where there is water or in moist environment because of their skin and how important it is to keep their skin moist.

Amphibians breathe through their skin and this can be called cutaneous respiration. Their lungs are not well developed therefore they undergo a very slow diffusion of oxygen through their blood.

For Amphibians that are larger than bull frogs, they obtain a very sufficient rate of diffusion of gases due to the following reasons:

a. Internal surface area of the lungs: Amphibians that are larger than bull frogs tend to have a more developed respiratory organs which means there lungs have a larger surface area and they are well developed.

b. They have a different body shape: Amphibians larger than bull frogs could have a flat or ribbon shape and their body shapes make it easier for respiratory gases like oxygen to permeate or enter their skin easily.

This DNA molecule is replicating - write a complimentary strand to this template TAC GGG CAG CAT AAA ATC​
Firdavs [7]

Answer: The complimentary strand will read ATG CCC GTC GTA TTT TAG

Explanation:

The complimentary strand to the replicating DNA molecule is known as messenger RNA (mRNA).

The mRNA directs specific bases to pair the existing base on the replicating DNA strand:

- Adenine (A) pairs only with Thymine (T)

- Guanine (G) pairs only with Cytosine (C)

So, to obtain the complimentary strand of TAC GGG CAG CAT AAA ATC​, substitute each letter with its base pair.

Thus, the complimentary strand will read ATG CCC GTC GTA TTT TAG

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 :)

State the role of mirror​
kvv77 [185]

Answer:

Mirrors are essential to every home. They help us in our daily mundane lives, though we rarely ever really appreciate their usefulness. From the moment we get up at night to the time we ready ourselves for sleep, we almost always seek for a mirror to take a look at ourselves. Mirrors reflect to us how we look, how clothes fit us, and how things fit.

Based on these data alone, identify the most appropriate hypothesis that explains the effect of peptides 1 and 2 on the quorum-s
DochEvi [55]
Data shows results of an experiment which was added to each peptide to culture the TRAP. Mutants of S. aureus and culture of the Agr. mutant of s. aureus.
Peptide 1 and three blocks Agr pathway
Peptide 2 blocks TRAP pathway
This is because the mutants are already blocked for one of the pathways.
Therefore it gives way to determine which pathway each peptide act on.
