Biological molecules such as proteins and DNA reveal differences between humans and chimps that would have taken around 7 million years to accumulate.
<h3>What is DNA?</h3>
All known animals and viruses have genetic information in the form of deoxyribonucleic acid, a polymer consisting of two polynucleotide chains that coil around one another to form a double helix. Ribonucleic acid is a type of nucleic acid, as is DNA.
The two DNA strands are known as polynucleotides because they are constructed from simpler monomeric units called nucleotides.
The four nucleobases that contain nitrogen—cytosine (C), guanine (G), adenine (A), or thymine (T)—along with deoxyribose and a phosphate group—make up each nucleotide. The sugar of one nucleotide and the phosphate of the following make covalent bonds, creating what is known as the phospho-diester linkage, which results in an alternating sugar-phosphate backbone.

Answer:
Natural Selection
Explanation:
In natural selection process of evolution, traits that are essential for an individual to be fit enough to survive under environmental stress become dominant.
Since the flowers are of blue or yellow color, it is essential for a bee to be able enough to perceive the blue and yellow color. Hence, the eyes of bee with time have evolved to perceive these two color so that they can pollinate flower.
Answer:
To drain his bile into a controlled via in order to fasten the healing process and avoid possible leakages of bile into other parts of the body.
Explanation:
A T-tube is a draining tube used <em>to </em><em>provide external drainage of bile</em><em> into a controlled via during the healing process, </em><em>this prevents the build-up of bile and therefore its leakage from the common bile duct into the tummy</em><em>, avoiding a potentially life-threatening infection. </em>

The correct option is DIVERSITY AND UNITY.
Evolution is able to explain how living organisms developed from an earlier forms which become extinct and are replaced by more developed organisms and how the living organisms show uniformity in some instances even though they are different.
Answer:
Individual Population Community Ecosystem
Explanation:
Individuals make up a population; populations make up a species; multiple species and their interactions make up a community; and multiple species and their interactions make up ecosystems when you include the abiotic factors.
