In your own words, explain how a person may taste the bitterness of PTC by using the following vocabulary words in your explanation (choose any order): trait, gene, genotype, phenotype, and alleles. Underline each word as you use it in your explanation. In this explanation, you can treat PTC taste sensitivity as a single gene trait. [As mentioned in the video, it may be more complex than a single-gene trait.]

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
