Using information given answer the following question. males decreases within about five months (3-4 generations).The effects of predators on guppy coloration have beenstudied in artificial ponds with mild, aggressive, and nopredators, and by similar manipulations of natural streamenvironments (Endler, 1980).Assuming ideal conditions with abundant food and space andno predators, what would happen if a mating pair of guppieswere placed in a large pond?The guppy population would grow slowly at first, then would grow rapidly, andthousands of guppies would fill the pond.The guppy population would never become very large, because only organismssuch as insects and bacteria reproduce in that manner.O The guppy population would grow slowly, as guppies would have only thenumber of babies that are needed to replenish the population.O The guppy population would continue to grow slowly over time. Use the following information for Questions 5-7:Venezuelan guppiesGuppies are small fish found in streams in Venezuela. Maleguppies are brightly colored, with black, red, blue andiridescent (reflective) spots. Males cannot be too brightlycolored or they will be seen and consumed by predators, but ifthey are too plain, females will choose other males. Naturalselection and sexual selection push in opposite directions.When a guppy population lives in a stream in the absence ofpredators, the proportion of males that are bright and flashyincreases in the population. If a few aggressive predators areadded to the same stream, the proportion of bright- coloredmales decreases within about five months (3-4 generations).The effects of predators on guppy coloration have beenstudied in artificial ponds with mild, aggressive, and nopredators, and by similar manipulations of natural streamenvironments (Endler, 1980).

Assuming ideal conditions with abundant food and space and no predators, what would happen if a mating pair of guppies were placed in a large pond? O The guppy population would grow slowly at first, then would grow rapidly, and thousands of guppies would fill the pond. O The guppy population would never become very large, because only organisms such as insects and bacteria reproduce in that manner. O The guppy population would grow slowly, as guppies would have only the number of babies that are needed to replenish the population. O The guppy population would continue to grow slowly over time.

Consider the following scenario and respond to the question below. A population of bird exists with variation in beak size, from small to medium to large beaks. This population experiences a shift in climate that affects food supply. Previously, the birds consumed insects, which was a diet perfectly suited to medium-sized beaks. Insects are less available following the change in climate. Now, fruits and seeds are the abundant food type. These are most successfully acquired by large beaks (for fruits) and small beaks (for seeds). Which best explains the expected role of natural selection in this scenario? Group of answer choices The entire bird population (of all beak sizes) will go extinct. Birds in this population with larger and smaller beaks will have higher reproductive fitness than birds with medium-sized beaks based on ability to acquire sufficient food. Birds with medium-sized beaks will undergo change in their lifetime to either shrink or grow their beak size to adapt.…
Which of the following best states a condition which promotes natural selection of aspecies? Group of answer choices One baby albino alligator, from a nest of 20 eggs, hatches in the Florida Everglades. An ocean ecosystem consists of more algae than fish species. The population of moths in a forest increased from 100 to 150 members. A female cat has a litter of 5 kittens instead of 6.
Select the three conditions necessary for natural selection. (select 3) heritability variation competition leading to differential reproductive success environment choas industrialization
A difference in survival and reproduction among members of a population that vary in one or more traits is called ________.
TRUE/FALSE. Disruptive selection creates alleles that increase genetic diversity in a population. If false explain why and if true explain why
Which of the following is NOT an example of an r-selected population? Select one: a. Mosquito lifespan is between 42 and 56 days for females and 10 days for males. b. Minnows spawn 16 to 26 times per year, yielding up to 10 000 eggs per female. c. Houseflies are very tolerant of a wide range of environmental conditions and thus have a broad range of habitat. d. Algae are capable of reproducing asexually and sexually to take advantage on the conditions of the environment.
The graph in Figure 3 represents the beak sizes of the offspring of the birds that survived the drought of1977. (The survivors were represented by the black bars in Figure 2, and this graph shows the beak depth distribution of their offspring in 1978.) Explain the observed change in beak characteristics using the following concepts in your answer: competition, survival of the fittest, inheritance.
Perform research to find at least two articles on the following topic: “The effects of climate change on polar bear populations”. You must find one article based on primary research and one based on secondary research. After reviewing the articles, recreate and complete the table below.
Using grey squirrels as an example, describe a population that would be of interest to a researcher. How would your approach to squirrels differ if you were going to measure tail length on a sample vs doing a census? Using white tailed deer as an example, describe a population that would be of interest to a researcher in Central Illinois. What variable might be of interest?
Which is an example of an evolutionary adaptation? Group of answer choices constancy in the rate of accumulation of genetic changes in a molecule over time the loss of an allele in a population due to a population bottleneck fixation in a population of a selectively advantageous allele a change in frequency of a neutral allele by genetic drift
Florida Scrub Jays live in extended family groups in which one pair breeds and all of their relatives help take care of the chicks. At night all the members of a family would perch near the nest. What spatial distribution would this represent? Group of answer choices -clumped -over dispersed -random -complicated
Which is an example of disruptive selection? Group of answer choices Drug resistance increases with each generation; the resistant bacteria survive, and the nonresistant bacteria get killed off. Swiss starlings usually lay four or five eggs, thereby increasing their chances of more offspring. Over time, Equus developed strength, intelligence, speed and durable grinding teeth. Panay island snails mainly have two different phenotypes, black and white shells.
