Quick Answer: This Experiment Is An Example Of Hypothesis-based Science. What Question Did The Researchers Ask?

What was the researchers main hypothesis?

What was the researchers’ main hypothesis? Researchers further hypothesized that if predation pressure is reduced, drab coloration would become less beneficial (since females prefer brightly colored mates).

Which of the following is an example of hypothesis based science?

Here are some examples of hypothesis statements: If garlic repels fleas, then a dog that is given garlic every day will not get fleas. Bacterial growth may be affected by moisture levels in the air. If sugar causes cavities, then people who eat a lot of candy may be more prone to cavities.

Can predation result in natural selection?

Selective predation can lead to natural selection in prey populations and may alleviate competition among surviving individuals. The processes of selection and competition can have substantial effects on prey population dynamics, but are rarely studied simultaneously.

Why did dark-colored rock pocket mice first appear in the population?

Why did dark-colored rock pocket mice first appear in a population of light-colored rock pocket mice? They have a genetic mutation that affects their fur color. They have a genetic mutation that affects their fur color. You just studied 28 terms!

What is hypothesis example?

Examples of Hypothesis:

  • If I replace the battery in my car, then my car will get better gas mileage.
  • If I eat more vegetables, then I will lose weight faster.
  • If I add fertilizer to my garden, then my plants will grow faster.
  • If I brush my teeth every day, then I will not develop cavities.

What is a good hypothesis example?

Here’s an example of a hypothesis: If you increase the duration of light, (then) corn plants will grow more each day. The hypothesis establishes two variables, length of light exposure, and the rate of plant growth. An experiment could be designed to test whether the rate of growth depends on the duration of light.

What hypothesis means science?

scientific hypothesis, an idea that proposes a tentative explanation about a phenomenon or a narrow set of phenomena observed in the natural world. The notion of the scientific hypothesis as both falsifiable and testable was advanced in the mid-20th century by Austrian-born British philosopher Karl Popper.

How do you start a hypothesis?

However, there are some important things to consider when building a compelling hypothesis.

  1. State the problem that you are trying to solve. Make sure that the hypothesis clearly defines the topic and the focus of the experiment.
  2. Try to write the hypothesis as an if-then statement.
  3. Define the variables.

How do you explain natural selection?

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Is predation a selection pressure?

Food acquisition is also a selective pressure. For example, sharp teeth and the ability to hunt prey are advantages for carnivores. Of course, predation is its own kind of selective pressure – in other words, those very carnivores are a selective pressure for their prey.

How does predation drive natural selection?

The take home in all of this is that predators are effective agents of natural selection because they possess key traits that allow them to capture and consume their prey; they adopt different strategies to do so, and they are common, but not too common, such that they can drive prey evolution without driving prey

Why is the belly of dark pocket mice still white?

Why do dark-colored rock pocket mice on dark lava flows have white bellies? There is no selection for dark bellies by visual predators. Mutations causing dark bellies do not occur. There is a reproductive advantage to having a dark belly.

Which best describes the results of natural selection?

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

What does Dr Carol mean when he says well mutation is random natural selection is not?

What does Dr. Carroll mean when he says “while mutation is random, natural selection is not”? – natural selection can favor some mutations and not others. – selection can change depending on environment. -mutations for advantageous traits are more likely to be passed on to next generation.
