Hayden has placed a cricket in a terrarium. he is interested in learning about cricket behavior. which of the following is a question about cricket behavior that hayden can answer through a scientific investigation? a. how will the cricket behave if another cricket is introduced into the terrarium? b. do crickets make better pets than lizards? c. how will the cricket feel if the terrarium is left in a dark room for several days? d. does a cricket prefer to live in the wild or in a terrarium?

How will the cricket behave is another cricket is introduced in the terrarium?

The correct answer will be option-A.

Explanation:

Cricket is an insect closely related to the grasshoppers of which 900 species are known.  

If an experiment is performed which includes the cricket through the scientific method then the scientific question which could be asked would be related to the behavior of the cricket in the presence of another cricket in the terrarium.

This could be the best scientific question as the behavior of the cricket can be observed easily and the hypothesis could be predicted. The experiment can be performed which could lead to the real answers.

Thus, option-A is the correct answer.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

the  frequency of a wave represents  the number of wavelengths that pass a specific point per second. the unit for  frequency  is hertz (hz).
