Over time, natural selection causes the beetle population to evolve. If the environment in which they are living is stable (i.e. the leaves stay the same), which variety of beetle would you expect to become more common in the population?

A. coloration
B. Variety A

(NEED HELP ASAP)

A

"Natural Selection

Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift.

Darwin’s grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles:

Two large green beetles and one brown beetle.There is variation in traits.

For example, some beetles are green and some are brown."

"The more advantageous trait, brown coloration, which allows the beetle to have more offspring, becomes more common in the population. If this process continues, eventually, all individuals in the population will be brown."

Answer: I did the test its B

D. Directional selection

I am doing a science homework and i need help answering these questions.

1. There are two methods scientists use to determine the age of fossils: the law of superposition and radiometric dating. Describe each of these methods and evaluate which one provides a more precise measurement.

2. Pictured below is an image of a bat (left) and a whale (right). Both creatures use echolocation: the ability to determine the distance of an object or another animal through echoes. Explain whether a. these two species evolved by convergent or divergent evolution b. the ability to use echolocation is an analogous or homologous characteristic

3. Explain how the theory of common descent can be further supported by each of the following methods: a. Comparing the embryonic development of two species b. Comparing the DNA sequences of two species

4. The peppered moth (left) is an organism that was commonly found on tree trunks in forests in the United Kingdom. In 1848, the first black peppered moth (right) was recorded in the Manchester area. After the Industrial Revolution, pollution darkened the color of the tree bark. By 1895, 98% of peppered moths in Manchester were black. a. Explain how the black color could have begun in the peppered moth population. b. Explain how the number of black peppered moths in the population increased between 1848 and 1895.

5. Which of the following is an example of a behavioral adaptation? a. Porcupines have developed sharp quills to protect against predators b. Arctic rabbits have fur that turns white in the winter to camouflage against the snow c. Bears hibernate throughout the winter to store energy d. Sharks have developed a torpedo shape to help them move quickly through the water

6. A colony of black beetles lives in a garden. When the gardener planted new flowers, a red beetle living in the soil of the flowers was introduced to the black beetles in the garden. After a few generations, half of the beetles in the population were red. Identify whether evolution in this population occurred as a result of genetic drift, gene flow, nonrandom mating, a mutation, or natural selection. Justify your answer with scientific reasoning.

7. Male peacocks are famous for their bright, colorful tails. The females, known as “peahens,” prefer peacocks with the biggest, brightest tails. Mating as a result of this preference causes a decrease in genetic variation in their offspring.Explain if evolution has occurred, and if so, what type.

8. Foxes often travel in groups called “skulks.” A small skulk of red foxes migrates to a region where many silver foxes live. The red and silver foxes mate with each other, resulting in an increase in red fox offspring.Explain if evolution has occurred, and if so, what type.

I would really appreciate it if you could help! brainliest included! please help!
