<span>John can use Cladistic
Analysis as an approach to trace the classifications of the lion and cat
because he can trace a common ancestor for them due to the cat and the lion
having the same characteristics and traits. They are considered to be closely
related because they share a common ancestor which means that they are closely
connected. The earliest discovery of using this method was by Peter Chalmers
Mitchell in 1901 as he was studying how different types of birds belong to the
same ancestry.</span>

Explanation:
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and then condense it to chromatin.
Histones include five main classes of relatively small basic proteins containing relatively large amounts of lysine and arginine. Nucleosomes are made of two each of four types of histones.
A) part a is cell wall part b is chloroplast
Symbiosis can vary between mutualism, parasitism, and commensalism, tho these grade into each other, it is often difficult to tell which is involved in a given relationship.
In GIFT, the sperm and eggs are just mixed together before being inserted and, with luck, one of the eggs will become fertilized inside the fallopian tubes. ... With GIFT, fertilization actually takes place in the body rather than in a petri dish. However, in vitro fertilization techniques have become more refined.
