Apiece of plastic (sample q), was heated at a constant rate. after 20 minutes of adding heat, the plastic melted. when an identical piece of plastic (sample r), was heated with twice as much heat per minute, the plastic melted in 10 minutes. how do the melting points of the two pieces of plastic compare? a. the melting point of sample r is double that of sample q. b. the melting points of sample q and sample r are the same. c. the melting point of sample r is slightly higher than sample q's. d. the melting point of sample q is higher than sample r's.

The answer is B.The melting points of sample Q and sample R are the same.

The melting points of sample Q and sample R are the same.

slitherio is the original. its the best friend of all middle schoolers. the man you can count any time you have some free time. slitherio is the guy you hang with while you're in the computer lab suppose to be doing "research or whatever". slitherio isn't just a game but a friend.

wormaxio is just a fake trying to squeeze its way into the friend group. trying to pretend its cool and your best pal but how long has it really been there for you, really. it only wants you as friend to boost its social status. wormaxio is just annoying fake pleb. no offense

you and have a wonderful day

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
