Answer:
The correct answer is option A, the type of isotope
Explanation:
The half life of a radioactive substance is a constant value and thus it is not affected by the temperature, catalyst or mass of the substance. Basically it is the time taken by a radioactive substance to reduce its mass by half of its actual value. Radioactive decay takes place only when the atomic nucleus becomes unstable and thus the isotope type is the only factor which affects the radioactive decay of any element.

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.
