Black bears in the north hibernate mostly due to the scarcity of food during the winter months.
Prior to hibernation bears are foraging for food. They eat fruit, nuts, acorns, insects, and certain leaves and plants. They catch occasional small animals, but lack agility to catch most adult prey. In the months before hibernation black bears can gain up to forty pounds of fat per week.
9. What types of food molecules is the bear consuming (give at least two)?

3. Which part of a flower devel-
ops into a fruit? into a seed?

I need a argument to: Differences in the structure of protein molecules affect how they connect to other protein molecules. This can result in different traits

Jorge is testing the effect of lead on child development. Based on his observations, he finds that the longer the children are exposed to lead-based paint, the higher the chance becomes that the children may develop behavioral problems. He has done repeated experiments, and his results are similar to the results of many other scientists.

Why is this scenario considered a theory rather than a hypothesis?

It is a testable scenario.
It is based on prior knowledge.
It is a well-tested explanation.
It is a factual statement.
