Answer:
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water  
 
Physical property is defined as the property of a substance which becomes evident during physical changes. Water is liquid at room temperature whereas hydrogen and oxygen are gases at room temperature.
Chemical property is defined as the property of a substance which becomes evident during chemical changes. Water reacts with metals to form bases, hydrogen reacts with metals to form hydrides and oxygen reacts with metals to form oxides.

Answer:
The correct answer is option B. "Flowers on Peak 1 and flowers on Peak 4 are genetically identical".
Explanation:
Phylogenetic trees are graphical representations of the relationships among species, at which the closer two organisms are, the closer they are put together in the tree. Modern phylogenetic trees are constructed based on the anaylsis of genetic material, usually mitochondrial DNA. In this case, flowers with different phenotype and genotype were classified in a phylogenetic tree. Since flowers on peak 1 and flowers on peak 4 are grouped together it is safe to assume that the two organisms are genetically identical. I attached the missing figure.
