Answer: Gravitational potential energy
Explanation:
Gravitational potential energy is the potential energy a massive has on another heavy object due to gravity acting on both of them. It is also the energy stored in an object based on the position(mostly vertical) of the object.
Jacob's vertical standing position and the weight of the cliff shows they have potential energy.

What was a result of rail standardization? Railways were able to transport meat without spoilage. Trains provided cars with pull-down beds for overnight travel. Trains from different rail lines could use each other’s tracks.
Explanation
the internal validity is still manipulated by the researcher and the DV is measured.
The DV is a variable that is being measured/observed, whereas the IV is a variable that is altered to see how it impacts something else. The term "dependent" refers to the idea that the IV will have an impact on the DV.
<h3>What parallels exist between studies conducted in a lab and those conducted in the field?</h3>
Since experiments are the only way to reliably establish causality, laboratory and field experiments are comparable in that they are both helpful in determining cause and effect. Furthermore, because there is a high level of control over confounding variables, the two experiment designs have the potential to have high internal validity.

Answer:
<em>The correct option is a-cancer arise in cells that have alterations in genes</em>
Explanation:
Cancer occurs when there is the alternations in a previously occurring normal gene. Mutations in this gene might cause events such as the over expression of these genes which might lead to cancer development. Although cancer is inherited from one cell generation to the next, most cancers and the risk for cancer development are not inherited from one's parents; however, there are exceptions. Cancers can be inherited but majority of them arise randomly.
