<u>ANSWER:</u>
Scientific explanations are accepted when there is sufficient evidence to prove them right. In addition, scientific explanations must be logical to be acceptable and must match as much evidences as possible.
<u>EXPLANATION:</u>
- Scientific explanations explain something about the natural world by making use of observations and measurements.
- These are usually tentative proposals that need to be verified or proved to be true.
- The observations and measurements must prove the scientific explanation to be true or must support it so that it becomes acceptable.
Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.
<span>Of SiF4 and SiBr4, the atom SiF4 is more polar. This is because the cation of both molecules are Silicon, but the anions of each are different. In SiF4, the anion is Fluorine, which is more electronegative than the Bromine in SiBr4, which creates a larger dipole, which results in a more polar molecule.</span>
I don’t understand either
