Hey there,
Your question states:Hemophilia<span> is a disease that causes uncontrollable bleeding. If a father has it, all of his daughters will be carriers of the disease, and about half of his sons will have the disease.
An error in which macro-molecule is the cause of hemophilia?
Based on my calculations ,your correct answer would be </span>

basically because h<span>emophilia is a disease, and like the statement says above, if the fathers has it then the daughter's would also. The Nuclear acid would be the answer because the acid originates with the DNA, which means that if that is the case, this the fathers offspring would really have this problem.

As the days get shorter and the temperature drops, this bear overeats and stores food as fat to get ready for hibernation.
When hibernate, bears will keep sleeping so they won't get any food from outside so they need to collect the food before hibernating. They have to eat more food than usual and stored it as fat to keep them from starving. The fats also help keep them warm as they are insulating the heat.
