The right option is; A. Compounds can be separated by physical methods.
Compounds can be separated by physical methods is the statement about compounds that is false.
A compound is a molecule that is formed from the combination of two or more different chemical elements. The atoms of the different elements that form a compound are held together by chemical bonds (covalent and ionic) that are not easy to break. The component of a compound can only be separated by chemical means and not by physical methods. An example of a compound is water (H2O) which is composed of hydrogen (H) and oxygen (O) atoms.
Hypoxia is the state which oxygen is not available in sufficient quantities at a tissue level in the body to maintain the homeostasis. The graph shows the concentration of this condition in Long Island Spund from 91 through 09 in mg/L, showinng in the data that the west area of the region has more cases os hypoxia than the east. Therefore, between the options the one that is a true statement about how well oxygenated to support marine life the region was during that period is the letter C. most years, the water near New York has inadequate oxygen to support marne life.
Let me explain to you: Taxonomy helps us understand relationships amongst organisms on Earth by grouping similar organisms together and creating links between all living things on Earth. For example, in order to get <span>evidence they can use DNA structure, if a higher percentage of their DNA is shared then they are more closely related</span>
