Yes, it is the power of material evidence that wins.
- Evidence used to support or refute a scientific theory or hypothesis is known as material evidence.
- Evidence is also used by scientists in various contexts, such as when they apply ideas to real-world issues.
- Whether a person accepts the data as proof depends on their presumptions or views regarding how observations relate to a theory.
- A creative hypothesis is developed by a scientist and may be refuted by testing it against evidence or established truths.
- Evidence can refute a hypothesis by demonstrating facts that are at odds with it. In contrast, the presence of evidence does not preclude the possibility of future, undiscovered evidence supporting the idea.
Therefore, it is the power of material evidence that wins, not the authority of experts that
proves an answer in Science.

Answer:
Water transports important nutrients throughout the plant.
Explanation:
Much like blood in an animal, water is necessary for a plants survival, as it transports important nutrients from the soil all through the plant's stems and leaves.
Answer:
84.8%
Explanation:
Step 1: Given data
Bob measured out 1.60 g of Na. He forms NaCl according to the following equation.
Na + 1/2 Cl₂ ⇒ NaCl
According to this equation, he calculates that 1.60 g of sodium should produce 4.07 g of NaCl, which is the theoretical yield. However, he carries out the experiment and only makes 3.45 g of NaCl, which is the real yield.
Step 2: Calculate the percent yield.
We will use the following expression.
%yield = real yield / theoretical yield × 100%
%yield = 3.45 g / 4.07 g × 100% = 84.8%
