Angela is a serious basketball player, but lately she has been struggling. First, her legs started getting tired halfway through practice. Next, her bones started aching. This week, she feels like she can’t even take a full breath. Angela goes to see Dr. Chao. “I feel like my whole body is falling apart. How can there be so many different things going wrong with me at the same time?” Angela asks. Dr. Chao does a physical exam and asks Angela to take a few deep breaths. “Actually,” the doctor responds, “there’s only one small thing wrong with your lungs. Fortunately, there is a medicine that will improve all your symptoms right away.”

How can a problem in Angela’s lungs cause problems all over her body?

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
