Suppose that you discover a new species of gastropod in a deep-sea hydrothermal vent community. This species grows rapidly, reproduces at 3 months of age, and has several clutches of >20,000 eggs each year. It appears to follow a Type I survivorship curve (i.e., juvenile mortality is low, and most individuals survive to adulthood). The largest individual you observed is at least 150 years old.   When you submit your results for publication, one reviewer recommends rejection, saying your data are clearly flawed, while the second reviewer says you’ve made the most important discovery in modern population biology. Their reasoning is exactly the same. What is it about your results that is causing these reactions?

In Oct 2022, a chilling discovery was made in Vuvatu, a country known for its extensive volcanic landscapes. Scientists found the remains of a large organism that had no resemblance to any current form of life on Earth. The organism also had no resemblance to any fossils ever found, including the very few fossils ever recovered from Vuvatu (fossils are rarely ever found in Vuvatu since volcanic landscapes are generally not conducive of fossilization). The world buzzed with the possibility that this was a crash site for an extraterrestrial body. An extensive study of the uncovered remains was conducted by many research facilities. Their conclusions regarding the organism’s features are listed below: Physical features: The organism has a surprisingly soft and malleable exoskeleton that reflects ambient light, creating mesmerizing patterns. In fact, the remains highly suggest that most of its body parts are soft and blubbery rather than rigid. Habitat: Given its relationship with…

Of these choices, which best describes an organism's niche?   Question 10 options:   The set of conditions under which Libeg's law no longer applies   The area/conditions where all of its physiological tolerance ranges overlap   None of these are even close.   The places it could live after a few generations of adaptation   All of the locations where actual and potential evapotranspiration are equal.

A recent outbreak of ranavirus in salmon has you concerned.  During your fieldwork you’ve discovered that individuals that have a hard operculum (gill covering) survive best because the virus cannot gain access to the gills.  Individuals with a soft operculum suffer 64% mortality due to ranavirus infection.  The hard operculum is a dominant trait.  You surveyed your population and found AA: 36, Aa: 45, and aa: 21. Showing the math increases the possibility of partial credit. Clearly indicate in your answer: The allele frequencies (both p and q) of your current population The allele frequencies (both p and q) you expect in the next generation due to the ranavirus outbreak

I need help identifying which assumption of Hardy-Weinberg equilibrium is most affected, then indicating whether what is being described will act to establish or violate equilibrium, and lastly, whether the statement will increase or decrease that population’s genetic variation. Corals synchronize spawning to occur on a single night during a particular tidal event, such as a spring tide. On that night individuals release sperm and eggs into the water, which then form zygotes. Larvae are carried off by currents and settle elsewhere. What assumption is this breeding style affecting and what will it do to VG of that coral species?

Elephant shrews (Rhynchocyon petersi) are voracious insectivores that prey upon a wide variety of arthropods as well as worms. An American Zoological Association (AZA) accredited zoo received two male- female pairs of elephant shrews as part of a captive breeding program. In captivity the shrews were fed crickets, cockroaches, Tenebrio larvae (meal worms), annelid worms (earthworms) and cat food. The adult shrews flourished gaining weight and produced young. Baby elephant shrews however had high mortality and suffered bone deformities. Please note, the question asks about Elephant shrews, not elephants (Family Elephantidae) which are the group of large mammals with long trunks! Note: your answers must be specific and you must provide examples to support your statements. Vague and overly general answers will receive minimal credit Answer the following questions: A. How would you go about diagnosing what the nutritional problem might be? Please note, simply stating that you would…

A- the two nematode populations have undergone complete speciation B-  individuals reared on different bacteria produce offspring that have a better chance of survival C- The populations appear to be most likely in the process of speciation D- all individuals were equally reproductively successful regardless of mate combination

U.S. coral reef ecosystems cover less than one percent of the Earth's surface yet are among the most diverse and productive communities on Earth. We rely on reef ecosystems for food, shelter, tourism, and recreation. Despite the importance of reefs, these ecosystems are in trouble. Scientists are working to understand the extent of and reasons for the decline of coral reefs and to provide managers with more effective ways to protect them. A. Think of the distributions of stony coral and how it seems to be the most prominent. A scientist wants to figure out if this has to do with the stony coral growing on multiple substrates. i. Identify a reasonable hypothesis that would help guide the scientist to their answer. ii. Identify the dependent variable in your proposed hypothesis. iii. Explain how the results of the experiment might be affected by other influences in the ecosystem. B. Use the map to identify the following: i. Identify the predominant locations where coral reefs are…

If we compare DNA sequences of related species pairs (human vs. gorilla and D. melanogaster vs. C. elegans), which species pair is likely to show the most adaptive differences with the related species? Is it the human-gorilla pair or the fruitfly-nematode worm pair? Justify your answer.
