When Charles Darwin introduced the theory of evolution through natural selection 158 years ago, the scientists of the day argued over it fiercely, but the massing evidence from paleontology, genetics, zoology, molecular biology and other fields gradually established evolution's truth beyond reasonable doubt. Today that battle has been won everywhere—except in the public imagination. Embarrassingly, in the 21st century, in the most scientifically advanced nation the world has ever known, creationists can still persuade politicians, judges and ordinary citizens that evolution is a flawed, poorly supported fantasy. They lobby for creationist ideas such as “intelligent design” to be taught as alternatives to evolution in science classrooms. When this article first went to press in 2002, the Ohio Board of Education was debating whether to mandate such a change. Prominent antievolutionists of the day, such as Philip E. Johnson, a law professor at the University of California, Berkeley, and author of Darwin on Trial, admitted that they intended for intelligent-design theory to serve as a “wedge” for reopening science classrooms to discussions of God.
The good news is that in 2005 the landmark legal case Kitzmiller v. Dover in Harrisburg, Pa., set binding precedent that the teaching of intelligent design in U.S. public schools is unconstitutional because the idea is fundamentally religious, not scientific. The bad news is that in response, creationists have reinvented their movement and pressed on. When they lost the ability to claim that creationist ideas are valid science, they switched to arguing that they were only supporting “academic freedom.” Worse, to further obscure the religious roots of their resistance, they now push for “critical analysis” of climate change, cloning research and other scientific endeavors that they paint as culturally oppressive.Explanation:
Which of the following dietary fats is considered to be the least healthy?
Trans unsaturated fat
All dietary fats are unhealthy
Cholesterol
Saturated fat
Fats that increases the bad cholesterol in the body are considered worst. Thus, Trans unsaturated fat is the correct answer.
What are trans fat?Unsaturated fatty acids have the presence of double bonds. This double bond is either 'cis' or 'trans' in origin.
When the unsaturated compounds are linked through trans bond, they form trans fat.
Trans fat are produced through chemical reaction. This reaction is termed as partial hydrogenation.
Trans fats have shown potential damage to the human body in research studies. Trans fat raises the bad cholesterol level (more lipid, less protein) in the body.
This can lead to several heart disease, liver damage or even atherosclerosis. Such diseases can be life threatening.
Trans fat are found mainly in fried and processed food. The junk food also contains high levels of trans fat.
Therefore, consumption of trans fat should be avoided for health safety.

Explanation:
An exotic species is the same as an invasive species.
True
False
Answer:
False
Explanation:
Exotic species are species brought to and unfamiliar environment, just like invasive species. There is a difference between the two however. Exotic species are indeed not native to their environment, but unlike invasive species, they are not harmful to the ecosystem. In order for an exotic species to become invasive, it must out-compete native organisms for food and therefore cause harm to the ecosystem. Non-native species that do not out-compete species remain exotic and not a high risk of disrupting the ecosystem.

Answer:
Incomplete dominance
Explanation:
In genetics, incomplete dominance refers to an inheritance mode in which two gene variants (i.e., alleles) of the same locus combine in a way that neither allele dominates the other. This phenomenon is similar to codominance, but in this last case, both alleles are dominant. Incomplete dominance produces a new phenotypic trait resulting from the combination of both non-dominant alleles. An example of incomplete dominance includes the pink color of snapdragons resulting from the cross of red-flowered snapdragons with white-flowered snapdragons.

walrus often dive for 5 to 8 minutes suggest why having over three times as many red blood cell as humans help them perform this function
Walrus often dive for 5 to 8 minutes because their red blood cells (that carry the oxygen) are exceptionally large. In addition, they have lots of myoglobin in their muscles that can store oxygen.
Why do Walrus have high blood circulation?The walrus can remain under the surface of the water for up to 10 minutes. They will usually surface every 5 to 8 minutes to get air and stay at the surface for about 1 minute. They will stay in the shallow waters, no more than 262 feet below the surface.When they dive the blood flow is cut off from their skin, extremities, and stomach. All of these adaptations allow for efficient and lengthy use of oxygen stores. They have a larger percentage of blood in their bodies to carry oxygen, about 12 percent of their weight as compared to only 7 percent for humans.To learn more about Walrus, refer to:https://brainly.com/question/25164635

Describe the modification of FGF5 pre-mRNA that leads to the production of both the FGF5-L and FGF5-S proteins.
Answer:
Splicing of exons and exclusion of introns
-mRNA that is transcribed from DNA usually has large regions of genetic code that just do not code for anything. This is a pretty conserved phenomenon among eukaryotes, to have meaningless sequences of DNA (introns) separating the meaningful sequences of DNA (exons). Introns must be spliced out of mRNA so that its translation leads to a functional protein.
Explanation:
Which of the following is true regarding the process shown below?
A. This process is cloning and involves the production of RNA from protein molecules.
B. This process is replication and involves the production of DNA from RNA.
C. This process is translation and involves the production of proteins from RNA.
D. This process is transcription and involves the production of proteins from DNA.
Answer:
C. This process is translation and involves the production of proteins from RNA.
Explanation:
- In the process of protein synthesis, the first step is called “transcription”. In transcription, the mRNA (messenger RNA) unwinds DNA base pairs, and pairs it with the single strand of RNA (A,U,C,&G) . Then the mRNA moves out of the nucleus and into the cytoplasm to ribosome. That process is called “translation”. In translation, there is a molecule called tRNA (transfer RNA). There is an amino acid which corresponds to the base pairs of RNA in top, which will create a chain of amino acids.
Answer:
Translation

What information can a pyramid model tell a scientist about an ecosystem? How might such models be used?
Answer:
The structure of ecosystems can be visualized with ecological pyramids, which were first described by the pioneering studies of Charles Elton in the 1920s. Ecological pyramids show the relative amounts of various parameters (such as number of organisms, energy, and biomass) across trophic level
Explanation: hope it helps
Answer:
Explanation:
A pyramid of numbers shows graphically the population, or abundance, in terms of the number of individual organisms involved at each level in a food chain. This shows the number of organisms in each trophic level without any consideration for their individual sizes or biomass. The pyramid is not necessarily upright
This question may be completed independently or as a group exercise. You have learned that humans have 46 total chromosomes, and chimpanzees have 48 total chromosomes. Use other textbooks in biological anthropology and biology (or reputable online resources) to find the number of chromosomes in other organisms. Give an organism with considerably more chromosomes than humans. Give an organism with considerably fewer chromosomes than humans. Did your findings surprise you
Answer:
In comparison to humans, there are more chromosomes in the Hermit crab that is 127 pairs of chromosomes for a grand total of 254 and in Myrmecia pilosula has fewer chromosomes than humans.
The complexity of an organism or how advance is an organism has nothing to do with the number of chromosomes it had. The chromosome number is subject to change over time. Human ancestors had more chromosome numbers as compared to now but they are not advanced to us.

Moles are mammals that live underground and eat worms. The moles are adapted to use their sense of smell to locate their food. Which environmental change would MOST LIKELY allow for an increase in the number of moles born with a better sense of smell?
A.
More rainfall makes the soil harder for digging so the moles need to have a better sense of smell to locate the worms.
B.
Less rainfall causes the worms to come closer to the surface so the moles need to have a better sense of smell to locate the worms.
C.
More rainfall makes the soil easier for digging so the moles need to have a better sense of smell to locate the worms.
D.
Less rainfall causes the worms to burrow further underground so the moles need to have a better sense of smell to locate the worms.
Answer:
I think the answer is D
Explanation:
Because if there is less rainfall that will make it harder for the moles to look for the worms and to sense the worms so they will have to have sense harder or dig harder to get the worms. hope this helps!
Less rainfall causes the worms to come closer to the surface so the moles need to have a better sense of smell to locate the worms.
What are adaptations of moles?Moles are adapted to use their sense of smell to locate their food, which is mainly worms. In dry conditions, worms tend to come closer to the surface in search of moisture and as a result, moles would need to have a better sense of smell to locate the worms.
In this scenario, the moles with better sense of smell would be more successful in finding food and would be more likely to survive and reproduce, passing on their advantageous traits to the next generation. This would lead to an increase in the number of moles born with a better sense of smell.

20. Allosteric effectors: a. can cause large changes in enzymatic activity. b. can lead to a decrease in the availability of a protein. c. do not alter the sensitivity of a metabolic pathway. d. decrease the sensitivity of the enzyme at nearly all concentrations of substrate. e. alter enzyme activity by binding to the active site of an enzyme.
Answer:
a. can cause large changes in enzymatic activity.
Explanation:
An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.
When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy. Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.
Hence, an allosteric effector can cause large changes in enzymatic activity because it acts as an intermediary and mediates specific effect in a metabolic pathway.
