Explanation:
B.) Water can act as a solvent in many different solutions.
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.A water molecule consists of two hydrogen atoms and one oxygen atom. The three atoms make an angle; the H-O-H angle is approximately 104.5 degrees.Therefore, option B. is correct.

How is the age of the earth used as evidence of evolution?
Answers
Answer:
Explanation:
All radiometric evidence points to the age of the Earth as about 4.54 billion years old. The old age of the Earth is evidence for evolution, a change in the genetic makeup of a population over time.
Answer:
The age of the earth can be used as evidence of evolution because it withholds the past that we are capable of uncovering bit by bit. We excavate fossils buried in the ground which we use accordingly. The fossil record reveals that the deeper you go, the farther back in history you unearth. This is known as the Law of Superposition. With these fossils, we can compare and contrast the anatomy of closely related organisms and possibly uncover vestigial structures. All of which is evidence that evolution has taken place.
