Am amniotic egg is first developed in the reptiles.
The membrane and shell make a protective membrane that can provide a safe environment for the cells to divide, and embryo to develop. Animals having an amniotic shell are called as amniotes. The other body parts develop later on.
Answer:
The high energy electrons from chlorophyll to other molecules are transferred by this molecule.
Explanation:
NADP is an important molecule which is used in the production of energy in the form of ATP. During the process of photosynthesis it acts as a universal electron carrier. It accepts electrons and hydrogen atoms to form NADPH. NADPH then moves to the other location of reactions and there it donates the energy stored in bonds along with hydrogen and electrons to other molecules and again becomes NADP.

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
