This Experiment Is An Example Of Hypothesis-Based Science What Question Did The Researchers Ask?

Similarly, What question did the researchers ask can predation result in selection for color patterns in guppies?

What was the major hypothesis of the researchers? Predation causes guppies to choose towards more drab color patterns. Researchers also speculated that if predation pressure is removed, drab colouring would become less advantageous (since females prefer brightly colored mates).

Also, it is asked, Why did dark-colored rock pocket mice first appear in a population of light colored rock pocket mice quizlet?

Why did dark-colored rock pocket mice arise in a light-colored rock pocket mouse population? Their fur color is affected by a genetic abnormality.

Secondly, How did the types of data the researchers collected enable them to test their prediction?

How did the researchers test their prediction using the data they collected? The quantity and size of colored dots allowed researchers to compare the brightness of various populations in a quantifiable manner.

Also, Why do dark-colored rock pocket mice on dark lava flows have white bellies?

Why do dark-colored rock pocket mice with white bellies live in black lava flows? Visual predators make no selection for dark bellies. Having a black belly has a reproductive benefit. White bellies are a crucial component of camouflage.

People also ask, What hypothesis was Endler testing with this experiment What did he expect to find if his hypothesis was supported?

Predators, according to Endler, are to blame for most of the difference across populations. Guppies who shared their stream with predatory cichlids had fewer spots than guppies that lived with Rivulus. Adult guppies are preyed upon by cichlids. Rivulus exclusively eats young guppies.

Why did the population of desert mice change from light colored to dark colored after the volcanic lava turned the desert sand black?

[DR. NACHMAN:] [DR. NACHMAN:] [DR. NACHMAN: Predators select out mice that don’t match their backdrop, causing the population to alter hue through evolutionary time.

In what way were the mice living on dark lava rock in different regions different from each other?

Dark fur colored mice have a higher chance of surviving on the dark colored substrate than light fur colored mice since they do not hide well and are more visible to predators.

Why does the dark fur trade spread so quickly in mice that are on the lava flow?

How do reproductive isolation values change with geographic distance among pairs of dusky salamander populations?

In pairs of dusky salamander populations, how do reproductive isolation values fluctuate with geographic distance? The significance of reproductive isolation rises as the distance between them grows.

How did the drought lead to an increase in beak size in the medium ground finch population?

It consumes seeds of various sizes, depending on their size. The drought triggered a mutation in the finch population, resulting in greater beak sizes. During the drought, birds that could consume bigger, harder seeds survived and bred. The finch population under investigation has a variety of beak sizes.

For which type of products are concept tests thought to be less effective in predicting the success of a product?

Concept testing are regarded to be less efficient in forecasting product success for which types of products? Products that encourage new habits of consumption. A long-term reduction in a product’s sales signals the start of which stage of the product life cycle?

What role does the rock pocket mouse play in the desert food web quizlet?

If the environment promotes a certain fur color, it might be advantageous. What part of the desert food chain does the rock pocket mouse play? The color of a rock pocket mouse has an impact on its overall health. Remember that an organism’s “fitness” is determined by its capacity to survive and reproduce in its environment.

Why should we not view lactose intolerance as a disease in adult humans?

This collection of terms includes (89) Why shouldn’t lactose intolerance be considered an illness in adults? Dairy products were not consumed by adult humans until very recently in our evolutionary history.

What was Endlers hypothesis?

Predators, according to Endler, are to blame for most of the difference across populations. Guppies who shared their stream with predatory cichlids had fewer spots than guppies that lived with Rivulus. Guppies are prey for cichlids, who are voracious predators. Rivulus exclusively eats young.

What observations did Endler make about guppies spot brightness in the streams and in the presence absence of predators?

The Discovery of Endler Males in one pool had bright blue and orange splotches running down their flanks, while those farther downstream had just little specks of color towards their tails. Endler also noticed variations in the distribution of guppy predators, as well as the color and size of pebbles at various stream areas.

What do you predict would happen if you placed a population of guppies that had mostly drab male guppies into a stream with very few predators?

Researchers hypothesized that if drab-hued guppies were put to a pool containing only killifish, their kids would ultimately be more brilliantly colored (because of the female preference for brightly colored males).

When comparing scientific ideas and hypotheses, which of the following assertions is the most accurate? Scientific theories are broad, testable concepts that are supported by and make sense of a large number of observations.

Why did dark colored pocket mice first appear in a population of light-colored pocket mice?

Why did dark-colored rock pocket mice arise in a light-colored rock pocket mouse population? Their fur color is affected by a genetic abnormality. In the location where they dwell, there is black lava rock. Individuals alter their appearance to fit in with their surroundings.

Why did the dark colored mice living on dark lava flows have white underbellies?

predators won’t notice them because of the camouflage on the tops of their bodies. Because there is so much selection pressure for it to be dark, the mice’s underbellies are white; predators arrive from above.

Why are dark colored pocket mice found in the dark rocky areas of the desert?

QUESTIONS 1. The majority of rock pocket mouse populations have sandy-colored fur that matches the pale tone of the desert rocks and sand they reside in. Dark-colored rock pocket mouse populations, on the other hand, have been seen residing on black basaltic rock formations formed by volcanic lava flows.

How did the rock pocket mice on lava flows differ from mice in the surrounding desert?

[NARRATOR:] The rock pocket mouse fits in wonderfully on the desert sands, its light-colored fur shielding it from predators. On black lava, however, the mouse’s fur stands out, drawing the attention of the various critters that regard it as food. [DR. NACHMAN:] [DR. NACHMAN:] [DR. NACHMAN: These mice are the desert’s Snickers bar.

  What Is Implementation Science?

Why are some mice light-colored and some mice dark-colored?

The fur of rock pocket mice may be pale or black in color. Mice that mix in with their environment are difficult to spot by owls and other predators, as illustrated in the animation. In light-colored habitats, such as sandy deserts, the dark-colored mouse is more susceptible to predators.

In what way were the mice living on dark lava rock in different regions different from each other?

Dark fur colored mice have a higher chance of surviving on the dark colored substrate than light fur colored mice since they do not hide well and are more visible to predators.

How did the dark colored mutation came to be so common in some populations of rock pocket mice?

In a habitat with a dark-colored ground, such as the Pinacate lava flow, the dark-colored mouse enjoys a selection advantage. Because rock pocket mice breed swiftly and often, the frequency of this desirable characteristic would soon spread across the population.

What hypothesis did the researchers test in this study dusky salamanders are undergoing sympatric speciation?

In this study, what hypothesis did the researchers test? The distance between dusky salamander populations enhances reproductive isolation.

How did drought and rain storms on Daphne Major island affect the population of medium ground finches?

On Daphne Major, they recently noticed a variation in the size of the medium ground finch’s beak. Due to a drought in 1977, the amount of little seeds accessible to the birds was limited, forcing them to depend on bigger seeds that required a lot of power to open.
