Answer:
Patchy forest.
Explanation:
The patchy forest hypothesis is the second hypothesis that helps to explain the origin of the hominids. The hypothesis was developed by Peter Rodman and Henry McHenry.
This hypothesis suggest that the evolution of bipedalism is energy efficient in the environment that contain few tress. The patchy forest result in the dispersion of the forest and this might result in the energy efficiency of bipedalism by walking upright and collect their food with hands.
Thus, the correct answer is patchy forest.

Silent mutations are base substitutions that result in no change of the amino acid or amino acid functionality when the altered messenger RNA (mRNA) is translated.
The answer is D.
Species diversity has been increasing through decades of years.
Answer: Nucleotides are the monomers used for DNA synthesis. The mix also contains a template, DNA taq polymerase, buffer, reverse and foward primer and magnesium ions.
Explanation:
A PCR master mix is a premixed solution that has all of the components for a Polymerase chain reaction (PCR). This reaction is a laboratory technique that amplifies small fragments of DNA into millions of copies.
The master mix used for that contains dNTPs (nucleotides). In the DNA there are four types of nucleotides that are differentiated by the nitrogen base they have: adenine (A), guanine (G), cytosine (C) and thymine (T).
<u>Since nucleotides are the monomers that make DNA, they are found in the mix because they are the material for DNA synthesis.</u>
The reaction mixture also requires;
- DNA template, the sequence of DNA to be amplified
- DNA taq polymerase, a heat resistant enzyme that assembles nucleotides into a new DNA
- Salt buffer, for an optimum ionic environment and pH
- Oligonucleotide primers (reverse and foward), pieces of DNA complementary to the template. Each hybridizes with one of the DNA chains.
- Magnesium ions, a catalyst required by DNA polymerase to work
