Can somebody help me on 12??

Step-by-step explanation:

a. The blue curve represents the puppies weight because the graph only shows 2 years, humans aren't done growing until they are 14-20. You can see the pink line is still going up, which makes sense for a human. Dogs reach close to adult size after 1 year, and may grow a little more after, but it remains steady.

b. If the graph is to scale, then it appears this puppy has almost finished growing just after one year. It grew the fastest in the first 6 months, and then a little more the next 6, and it looks like it was finished growing after a little over a year.

The baby was a little slower to start, it looks like there was less growth the first 6 months, then the growth took off and the baby is continuing to grow quickly going off the chart before the 2 year mark.

At about 3 months it looks like the baby and puppy weigh the same, but the puppy continues to grow a little faster, at 8 months it looks like they weigh the same again, but the baby takes off in weight and the puppy only gains a little more.
