Chapter 27.1, Problem 1CSC
Summary Introduction
To explain:
Why the Mexican beaches become crowded.
Introduction:
In early nineteenth and eighteenth centuries, oil for lubricating the parts of machines and for lamps was harvested from the whales. In mid-1800s, there was a declination in the hunting of whale populations in the eastern Pacific near Mexico and California and the whalers had started hunting the northern elephant seals.

You are watching a documentary on television about grizzly bears in North America. The narrator is speaking over a clip of two cubs and their mother walking along a riverbank in a heavily wooded forest. She says that grizzly bear populations are rising for the first time in several decades even though deforestation is still a growing problem in North America.
Which of the following could be a possible factor for the increase in the grizzly population?
Loss of habitat
Reduction of resources
Increased industrialization
Higher birth rate over death rate
You are surveying of the turtle species identifies several breeding populations in different habitats across the island. After a very warm summer of 2020, you observe that the hatchlings from low-elevation nests are mostly males, whereas hatchlings from higher elevations have an equal female-to-male sex ratio. As a bit more background, temperature influences the sex ratio in some turtle species, a phenomenon called temperature-sex determination (TSD). With this knowledge, you hypothesize this new turtle species exhibits TSD, and that eggs incubated at low elevations during the warm year experienced a high enough embryonic temperature to skew the sex ratio. To test this, you collect 20 newly laid eggs in early 2021 & take them back to the lab to conduct an experiment to test your hypothesis that this species exhibits TSD. Assume you know the average nest temperature in the wild, and you have access to multiple incubators
Design an experiment to test the hypothesis that this turtle…
Due to its ability to camouflage itself from predators, the White Peppered Moth of England was once much more abundant than the Black Peppered Moth. As the Industrial Revolution hit, factories began to release black soot which coated everything, including tree bark. Because the moths’ habitat was now darker, the white moth became much more susceptible to predators. At the same time, the Black Peppered Moth was now more protected and began to increase in number.This story is an example of
A.
natural selection.
B.
extinction.
C.
endangered species.
D.
mutation.

- At the edge of the Arctic Circle, owls prey on field mice. Occasionally, in a litter of white field mice, a brown mouse appears. Because of greenhouse warming, the snow melts, changing the environment to shades of brown. What is most likely true regarding the brown mice before the greenhouse warming? The brown mice population was large in number. The brown mice population was small in number. The fur color of mice changed to white because they needed to survive. There were no brown mice born before greenhouse warming.arrow_forwardTigers are solitary animals that require vast amounts of forest landscape as their territory to roam. In order to protect one tiger, we must conserve around 25,000 acres of forest.

- Wildebeest are species of antelope found in southern Africa. The wildebeest herd in Serengeti National Park, Tanzania, is the largest herbivore herd on Earth. Scientists began monitoring the sizes of the Serengeti's large mammal populations in the 1960s. Over the next few decades, they noticed something unusual: the wildebeest population was increasing at a rate much faster than before. The scientists determined that this increase was due to several factors. One factor was a vaccination program that eradicated rinderpest, a viral disease that kills wildebeest. Based on the figure, what kind of population growth model would you use to represent wildebeest (circles) populations? wildebeest zebra 1960 1970 1980 1990 2000 year Figure 1.

Over time, one population evolves long ears and is more active near dark, when they can hear predators coming but the predators can't easily see their ears sticking up above the grass. The other rabbit population evolves short ears and is more active in the middle of the day; it is harder to see, but also doesn't hear predators approaching as well. Eventually the river dries up, and the rabbits start encountering each other again. What do you predict will initially happen when the populations first start to meet? O rabbits will avoid hybridizing, since it is usually a mistake rabbits will interbreed and have offspring with intermediate ears that are visible during the day and not as good at hearing predators at night O rabbits will know not to mate with any that don't have their same "ear size" O rabbits will already show complete reproductive isolation after one million years and will ignore each other, having…arrow_forwardWolves recolonized a large area around Grand Teton National Park (GTNP) in the late 1990’s. Wolf biologists started estimating the number of wolves in 2000 at 21 wolves in GTNP population. In 2010 they repeated their population surveys and counted 105 animals.The population growth rate of wolves is 8 per year.State biologists want to know how long it will take for this population to reach 175 wolves so they can delist them in this region of Wyoming. How long will it take for the population to reach this threshold, assuming growth stays the same?arrow_forward
- The Colorado potato beetle has a history of pesticide resistance. The graph shows the number of chemical insecticides used in agriculture that the Colorado beetle population has become resistant to from 1950 to 2010. It took longer for the population of potato beetle to develop a resistance to some insecticides. However, by 1990, the Colorado potato beetle population had developed a resistance to 35 different kinds of insecticides, and farmers ran out of insecticides they could use to control the beetle population. A new type of insecticide was introduced in 1995. 60 40 30 20 10 1960 1970 1980 1990 2000 Year of Report Which of the following best describes what happened from 1965 to 1975 and again from 1995 to 2000 to the insecticide resistance of the beetle population?
