Why would selection have favored ‘protocells’ that used DNA to store genetic information?
Group of answer choices
DNA is more stable and has a lower mutation rate.
DNA can evolve more quickly
Because DNA cannot catalyze reactions
DNA viruses are less harmful than RNA viruses.
DNA viruses are less harmful than RNA viruses.
Answer
DNA is more stable and has a lower mutation rate.
With the exception of certain viruses, DNA rather than RNA carries the hereditary genetic code in all biological life on Earth. DNA is both more resilient and more easily repaired than RNA. As a result, DNA serves as a more stable carrier of the genetic information that is essential to survival and reproduction.

CHOOSE THE BEST ANSWER Why did Natural selection ultimately favor DNA over RNA as the primary information molecule of life on Earth? DNA can store more information than RNA. DNA can replicate faster than RNA. DNA is more nutritious than RNA. ODNA is more stable and has a lower mutation rate than RNA. DNA is requires less energy to maintain and reproduce than RNA. Question 6 CHOOSE THE BEST ANSWER A major difference between Prokaryotes and Eukaryotes is that eukaryotic...
Why would natural selection not minimize costs (in the form of symptoms) of evolved defenses? (choose all that apply) Question options: Minimizing costs increases the risk of failing to kill a pathogen Minimizing costs could mean lower reproductive success The result of natural selection isn’t minimization of discomfort, it is optimal reproductive success (for genes, over many generations) If symptoms such as sneezing, coughing, fever, etc. are helpful, why aren’t we harming ourselves by taking medications to reduce these symptoms?...
Why can banks with greater equity financing borrow funds cheaper than other banks? Group of answer choices Because they have proportionately more financial leverage and hence less risk. Because a greater proportion of their assets have to be in default before they fail. Because they have less credit risk. Because they have lower required reserves.

Which statement explains why the recombination frequency between two genes is always less than 50%? Recombination cannot be more than 50% because chromosomes are only 50 map units in length. The genotype of the F, gametes will always be 50% parental gametes and 50% recombinant gametes. Genes with a recombination frequency near 50% are unlinked and have an equal likelihood of being inherited together or separately. F1 gametes always have 50% of their alleles from each parental...
PLEASE ANSWER ALL THE QUESTIONS: 1.What is true of tRNA (transfer RNA)? A they contain an anti-codon B they carry an amino acid C they can interpret the genetic code D all of these are true 2. How can transcription factors bound to distant enhancers influence gene expression? A the transcription factors can slide along the DNA until they get to the gene's promoter B DNA can loop, bringing these proteins into contact with the gene's promoter C both of...
4. In a lake governed by the food web shown in the image to the right, 500 brown trout are added from fisheries. Which of the following outcomes would most likely be expected? A. Tadpole population will increase B. Duck population will decrease C. Algae population will increase D. Lilly Pad population will decrease E. Caddis Fly larvae will increase 5. Which of the following pieces of evidence most strongly supports a common ancestor of all life on Earth? A....

Under nearly all circumstances, postzygotic reproductive
isolation cannot evolve under the direct action of natural
selection. Instead, postzygotic isolation evolves as a by-product
of other genetic changes as proto-species diverge. In contrast,
natural selection can directly act to enhance prezygotic
reproductive isolation. Consider two species with overlapping
ranges. If hybrids between the species are less fit than pure
species individuals, females that mated with heterospecific males
would be at a selective disadvantage, because their resulting
offspring had low fitness....

From the pages 571-587 attached below.
1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?
1b) What is this name...
Can I get a summary of this article name "Evolution Is Happening Faster Than We Thought" By MENNO SCHILTHUIZEN? — A FRIEND recently invited me over to see the blackbird that had taken up residence in a potted plant on her balcony. Serenely incubating eggs in the inner city, this bird had little in common with its shy, reclusive ancestors that nested in Europe’s forests. Early in the 19th century, probably in Germany, blackbirds began settling in cities. By the...
