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
The answer is C
Completing multiple trials during an experiment
The rest of the options are possibilities of how you can "mess up" and experiment, but if you run multiple trials doing everything right, for example, making sure all variables are controlled, using the right equipment, and making sure you cover all possible variables. If you make sure you do multiple trials and you do them right, you get successful results.
So the answer is C

Goodluck!!
The Bartholin's Glands, which are also known as the vestibular glands are a pair of pea size gland. The location of the Bartholin's gland is postrior to the vaginal orifice.
The main function of these Bartholin's gland is to secrete mucus and to lubricate the vaginal orifice. These gland is homologous to the bulbourethral glands present in the males.
<h3>Hence, the vaginal orifice is lubricated by secretions from the Bartholin's Glands.</h3>
Answer:
Adaptive immune responses are triggered by activation of antigen-specific T cells that produce antibodies against foreign antigens such as, for example, harmful viruses. These immune responses are useful to eliminate dangerous molecules from the body. In a normal immune reaction, the antibodies produced by T-cells target antigen molecules in order to be subsequently absorbed by phagocytic macrophage cells.
Autoimmune diseases are triggered by the response of the adaptive immune system against self-antigen molecules. Since the immune system can not eliminate antigens from the own body, this immune reaction generates an excessive inflammatory response, and it may lead to the damage of tissues and organs.
Answer: The reactants for Photosynthesis are the products for Cellular Respiration and the reactants of Cellular Respiration are the products of Photosynthesis.
Photosynthesis:
6CO2 + 6H2O -> C6H12O6 + 6O2
**6 Carbon Dioxide + 6 water -> Glucose + 6 Oxygen**
Cellular Respiration:
C6H12O6 + 6O2 -> 6H2O + 6CO2 + Energy
**Glucose + 6 Oxygen -> 6 Water + 6 Carbon Dioxide + Energy**
