Explanation:
Errors during duplication, errors during recombination, the movement of genetic elements, and dna damage
The right option is; c. can be used and consumed without risk
The defining characteristic of potable water is that it can be used and consumed without risk.

Answer:
Answer is Sinoatrial node, SA.
Explanation:
The sinoatrial node, SA, is known to be a group of cells which are found at the top of the heart.
The electrical signal that is initiated by the sinoatrial node bring about or stimulates the atria and then the ventricle of the heart.
It should be noted that, the sinoatrial node are regarded as the pacemaker cells.
This type of water transition or change in phase of matter is known as FREEZING.
Water has molecules that are free flowing and have the ability to collide and bounce against each other, that's why it has that kind of characteristic that it takes the shape of its container.
When these molecules are exposed to lower or colder temperatures, the molecules tend to vibrate and get attracted towards each other, creating a semi-solid or completely solid material. In this example, liquid turned into frost because of the low temperature present within the environment.
