A cell takes in DNA from the outside cell. This external DNA becomes part of the cell's DNA.

During transformation, a cell takes up foreign genetic material (such as DNA) from its environment and incorporates it into its own genome. This can lead to the expression of new traits or characteristics in the transformed cell. In biotechnology, transformation is commonly used to introduce specific genes into an organism for various applications.
During energy transformation, some of the heat released or transferred can be lost to the surroundings as waste heat, leading to a decrease in overall efficiency. Heat can also be used to drive other processes or reactions, ultimately converting some of its energy into useful work. In some cases, heat can be stored or managed to optimize energy transformation processes for improved efficiency.

A physical change involves a transformation in the appearance, shape, or state of a substance, while its chemical composition remains the same. This means that no new substances are formed during a physical change.
The heat produced during an energy transformation is typically released into the surrounding environment, where it can be absorbed and dispersed. In some cases, heat can be harnessed for other purposes, such as heating water or powering turbines in a power plant.
In any energy transformation, energy is never created or destroyed, but rather transferred from one form to another. This principle is known as the Law of Conservation of Energy.
