Although many transposons, DNA sequences that move within an organism's genome through shuffling or duplication, have become corrupted and inactive over time, those from the long interspersed nuclear elements (LINE) family appear to remain active in the genomes of some species. In humans, they are functionally important within the hippocampus, a brain structure that supports complex cognitive processes. When the results of molecular analysis of two species of octopus—an animal known for its intelligence—were announced in 2022, the confirmation of a LINE transposon in Octopus vulgaris and Octopus bimaculoides genomes prompted researchers to hypothesize that that transposon family is tied to a species' capacity for advanced cognition.

Which finding, if true, would most directly support the researchers' hypothesis?

a)
The LINE transposon in O. vulgaris and O. bimaculoides genomes is active in an octopus brain structure that functions similarly to the human hippocampus.
b)
The human genome contains multiple transposons from the LINE family that are all primarily active in the hippocampus.
c)
A consistent number of copies of LINE transposons is present across the genomes of most octopus species, with few known corruptions.
d)
O. vulgaris and O. bimaculoides have smaller brains than humans do relative to body size, but their genomes contain sequences from a wider variety of transposon families.Correct Answer: A

Although many transposons, DNA sequences that move within an organisms...

Choice A. This is the best choice. The text says that LINE transposons are important in the human hippocampus, which supports complex cognition. If the LINE transposon found in octopuses is active in a similar part of their brain, that would suggest that LINE transposons support complex cognition in octopuses too, which in turn supports the hypothesis that LINE transposons are linked to advanced cognition in general.

Choice B. This choice doesn't support the hypothesis. It doesn't include anything about how LINE transposons function in species other than humans.

Choice C. This choice doesn't support the hypothesis. It doesn't include anything about how the LINE transposon in octopuses might support advanced cognition.

Choice D. This choice doesn't support the hypothesis. It doesn't include anything about how the LINE transposon in octopuses might support advanced cognition.

Although many transposons, DNA sequences that move within an organisms...

Explanation:

Background Information:
- Transposons are DNA sequences that can move within an organism's genome.
- LINE transposons are still active in some species, including humans.
- They play a role in the function of the hippocampus, a brain structure important for cognitive processes.

Supporting the Hypothesis:
- If the LINE transposon in O. vulgaris and O. bimaculoides genomes is active in an octopus brain structure similar to the human hippocampus, it would directly support the hypothesis.
- This suggests a functional importance of the transposon in the cognitive abilities of octopuses.

Implications:
- The presence and activity of the LINE transposon in the octopus brain structure could explain the advanced cognitive capabilities observed in these animals.
- This finding would strengthen the link between the activity of LINE transposons and cognitive function across species.
Therefore, option A, which states that the LINE transposon in octopus genomes is active in a brain structure similar to the human hippocampus, would most directly support the researchers' hypothesis about the relationship between LINE transposons and advanced cognition in octopuses.

Question based on the following passage and supplementary material.This passage is from A. R. Kirchoff, “The New Ecosystems of the Anthropocene" ©2017 by College Hill Coaching.Scavengers—animals that feed on carcasses,rotting plants, or waste—get a bad rap.Yellowjackets and raccoons swarming aroundgarbage cans can seem like annoying pests at(5) best and germ-infested monsters at worst. Indeed,scavengers have been known to spread diseasessuch as meningitis, leptospirosis, and bubonicplague, so its no surprise that they are the focusof a huge extermination industry. But our habit of(10) eradicating irksome species ignores an importantfact: scavenger relationships are essential to allcomplex life.The selective pressures of scavenger behavioraccelerate the evolution of social intelligence.(15) For thousands of generations, some scavengerspecies have struggled to outwit the wily hunterswith whom they compete for scraps. Theymust predict, plan, and communicate as theyapproach a carcass in order to avoid becoming(20) the next prey. At the same time, hunters likeHomo sapiens had to become more clever toprotect their meat from these thieves. This socialinteraction has allowed at least one scavengerspecies to thrive in an anthropocentric* world:(25) Canis lupus familiaris—the domesticated dog.Your pet terrier would not be such a faithfulcompanion if its ancestor, the grey wolf, hadnot spend so much time picking over the trashof our hunter forebears. In just 20,000 years, we(30) have become symbionts,* turning a few lines ofwolves from freeloading foragers into friendlyFrisbee-fetchers.Even less perspicacious scavengers playa vital role in complex ecosystems, often in(35) unexpected ways. As plastic waste accumulatesrapidly in the ocean (and is expected to surpassthe total mass of fish by 2050), and toxicchemical waste continues to be dumped intoour water supplies, the role of one particular(40) class of scavenger, the decomposers, has becomecritical. These creatures break down complexmolecules into simpler ones in a process calledbiodegradation. Alcanivorax borkumensis, anaturally occurring marine bacterium, can(45) digest petroleum and convert it into foodenergy. Hydrocarbons like petroleum andplastics are energy-rich organic moleculesmuch like starches, fats, and proteins, sothe idea that they can be used as food by(50) opportunistic organisms is not so biochemicallyfar-fetched. After crude oil spills, cleanupcrews encourage this biodegradation by usingchemical dispersant to break the petroleuminto smaller droplets, thereby creating more(55) surface area for the bacteria to attack. Anotherdecomposer, Aspergillus tubingensis, is able togreatly accelerate the breakdown of polyesterpolyurethane, a petroleum product and one ofthe more durable plastics in our landfills and(60) oceans. Although environmentalists have yetto discover a practical method for harnessingA. tubingensis in large-scale waste mitigationsystems, such bio-technological solutions maynot be far off.(65) Our dependence on unicellular opportunistsgoes deeper still: our digestive processes,blood pressure, and immune system dependon thousands of species of scavenger bacteriathat live primarily in our gut and make up our(70) microbiome. These organisms patrol the intricatechemical pathways of the gut and perform dutiesthat, under normal circumstances, keep thingsrunning smoothly. The overuse of antibiotics,our favorite pharmaceutical pest-control system,(75) often compromise healthy systemic function bydestroying healthful bacteria as well as harmfulones. For instance, humans with depleted levelsof Butyricicoccus pullicaecorum in their intestineshave higher rates of chronic bowel diseases like(80) ulcerative colitis and Crohns disease. Researchinto how these microorganisms has explodedin recent years, particularly regarding how theyinteract with human chemistry to regulate ourhormones, our blood sugar, and even our mood.human-centeredspecies that live together in a mutually supportive relationship.Q.This passage primarily serves to

When the results of molecular analysis of two species of octopus—an animal known for its intelligence—were announced in 2022, the confirmation of a LINE transposon in Octopus vulgaris and Octopus bimaculoides genomes prompted researchers to hypothesize that that transposon family is tied to a species capacity for advanced cognition.Which finding, if true, would most directly support the researchers hypothesis?a)The LINE transposon in O. vulgaris and O. bimaculoides genomes is active in an octopus brain structure that functions similarly to the human hippocampus.b)The human genome contains multiple transposons from the LINE family that are all primarily active in the hippocampus.c)A consistent number of copies of LINE transposons is present across the genomes of most octopus species, with few known corruptions.d)O. vulgaris and O. bimaculoides have smaller brains than humans do relative to body size, but their genomes contain sequences from a wider variety of transposon families.Correct Answer: ACorrect answer is option 'A'.
