Answer:
<em>Read explanation.</em>
Explanation:
Well, because it plays such an important role in problem solving. Science is all about solving the problems, puzzles and riddles of this world and universe, and to do that, we elaborated something called the scientific method.
The scientific method is a method we follow to encounter, solve and understand certain problems. A famous example would be the "broken torch example":
Torch doesn't work → is it the batteries? → we try replacing the batteries
↓
or is it the circuit?
↓
we have concluded that it is not the batteries
↓
we try finding the problem in the circuit
↓
etc.
As you can see, in the example, the 2 possible problems that would explain why the torch isn't working, are our 2 hypothesis.

Sex linked traits can only be held on the X chromosomes, so males only need one while females need two. Since the daughter has it, it must mean the mother is a carrier and has one normal X chromosome and another with the recessive trait (c).
Answer:
A very small number of bone cancers (especially osteosarcomas) appear to be hereditary and are caused by defects (mutations) in certain genes. Retinoblastoma is a rare eye cancer in children that can be hereditary. The inherited form of retinoblastoma is caused by a mutation (abnormal copy) of the RB1 gene. Those with this mutation also have an increased risk of developing bone or soft tissue sarcomas. Also, if radiation therapy is used to treat the retinoblastoma, the risk of osteosarcoma in the bones around the eye is even higher. Finally, there are families with several members who have developed osteosarcoma without inherited changes in any of the known genes. The gene defects that may cause cancers in these families haven’t been discovered yet.
They will most likely survive becuase stage one of bone cancer is the most treatable stage.
