Chapter 54, Problem 6DA
Summary Introduction
To determine: The rate of population increase after 10 generations in mouse species.
Introduction: Horizontal gene transfer can be defined as the exchange of genetic contents between the unicellular and multi-cellular organisms that do not include the transmission of DNA from parent to offspring. This process is responsible for evolution by mixing the genetic material of two species.

Do explain.
Each August, dolphins near the coast of the Atlantic ocean. In a hypothetical situation, an initial population of 900 dolphins gives birth to 390 tiny babies, and during the next 12 months, 60 dolphins die.
Assuming the dolphin population grows geometrically, what will the dolphin population be in 12 years?
EVOLUTION ASSESSMENT - FINCHES
Galápagos Ground Finches
Between 1973 and 1978, the population of ground finches (a type of small bird) on the Galápagos Islands
decreased. Scientists made observations of the population throughout that time period. They recorded
and graphed differences in the distribution of traits over time. The two sets of graphs below come from
the data they collected.

- Two human populations have the same net reproductive rates (R0), but different generationtimes. In what ways are these two populations similar and different?arrow_forwardPeppered Moth Experiment Researchers wanted to further test the idea that Peppered Moth populations around London really shifted due to their increased visibility to predators on dark trees. Researchers constructed two sample forest plots, each surrounded by bird-proof netting. In both enclosures they captured ALL the moths and ALL the birds. Trees in each enclosure were stripped of lichens so they ALL had dark bark. The treatments for each enclosure were as follows: Enclosure A: 50 dark-colored moths and 50 light-colored moths were released. Enclosure B: 50 dark-colored moths and 50 light-colored moths were released, plus 10 birds. Proportions of dark and light moths were monitored in each enclosure for 10 years by thorough sampling (sampling did not harm moths). Results for moth populations after 10 years are reported in the chart below. In addition, the bird population in Enclosure B was remained fairly constant over the 10 years and no birds appeared in Enclosure A.

- 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.

- Give typing answer with explanation and conclusionarrow_forwardVery few species on Earth are completely r-selected or K-selected. Many species in their natural habitats demonstrate a life strategy that ranges along a continuum between r- and K-selected strategies. Use this information to answer the 3 sub-parts. a) Sea otters are marine mammals that live in northern Pacific coasts. Typical female sea otters reach sexual maturity around 3 or 4 years of age, and they reproduce once a year, producing a single pup.Only female sea otters are tasked with raising the offspring. Mothers constantly take care of their pups until they are 8 months old, but only 25% of the pups survive past the first year. Sea otter fur was highly sought after between the 18th century and the early 20th century. Through conservation efforts, the number of sea otters increased. The current world population is estimated to be between 1 000 and 2 000 individuals, and they are considered to be endangered. Their main food source is sea urchins, molluscs, and crustaceans.
