Answer:
Cancer cells are characterized by mutations associated with the uncontrolled growth of these tumor cells
Explanation:
Mutations in tumor suppressor genes are often associated with different types of cancers. On the other hand, mutations derived from the insertion of Transposable Elements may also activate cancer-related genes which are known as oncogenes
Answer:
The two factors are:
• The kind/type of surface involved.
• The force that the surface are being pushed together.
Explanation:
Friction can be said to be the general term used to describe the force that one surface exert on another when they rub against each other.
When the surface is partially not smooth or totally rough, a greater force is been needed to move one surface past the other.
The weight of the can also significantly be a key factor. This is where the need to friction reduction come to play a role; and need for friction reducers like lubricant, rollers etc helps.
