A phylogeny is an evolutionary ”tree” of related
organisms that can be constructed by using
information obtained from the genetic material.
Genetic information is contained in all living cells,
in the form of long DNA molecules that take the
shape of connected double- stranded spirals
(DNA stands for deoxyribonucleic acid). DNA
spirals, or “helixes”, are tightly compressed in the
nucleus of every cell. Their information is
organized into a code made up of four small
molecules — the building blocks of DNA. The
molecules, called nucleotides, are labelled:
A (adenine), C (cytosine), G (guanine) and T
(thymine).
It is possible to draw conclusions about the
evolution of a group of plant or animal species,
and the relationships among them, by comparing
selected pieces of DNA.

Answer:
Gene mutation:
Gene mutation may be defined as change or alteration in the nucleotide sequence of the gene. DNA replication errors and mutagens are responsible for the gene mutation. A single gene may affected in this mutation. For example: Sickle cell anemia is caused by the replacement of GAG to GUG results in the formation of valine instead of glutamic acid. The shape of RBCs changed from the biconcave to the sickle cell shape.
Chromosome mutation:
Chromosome mutation may be defined as the change or the alteration of chromosome number or structure. Chromosome mutation occurs due to errors during crossing over. The segment of the chromosome may get changed. Large number of genes may get affected. For example: Down syndrome occurs due to the presence of extra chromosome at chromosome 21.
Assonance is defined as when two or more words that are close to each other and they repeat same vowel sound but they start with a different consonant sound so the <span>line from "Safari Day in Kenya ” that contains an example of assonance is

Answer:
C. Impulsive
Explanation:
The question is related to "Alice's Adventures in Wonderland." This is a novel written by <em>Lewis Carroll</em>, an English writer of fiction stories for children. It talks about Alice's adventures upon falling down a rabbit hole.
The excerpt, <em>"In another moment down went Alice after it, never once considering how in the world she was to get out again," </em>shows her character of being "impulsive." With this trait, Alice didn't think twice before going down the hole and following the rabbit. She never thought about the consequences of her decision. This is also shown when she kept on following the rabbit instead of going back home.
So, this explains the answer.
