Answer:
I believe it is C
Explanation:
Scientists are still testing this theory so I believe it is a hypothesis.
Forgive me if I am incorrect.
Answer:
A. delivery of oxygen to tissue cells
Explanation:
Blood is a liquid tissue formed by different types of cells suspended in plasma. It circulates throughout our body, through veins and arteries. Veins carry blood from the organs and tissues to the heart, while arteries carry blood from the heart to the organs and tissues.
One of the basic functions of the blood is the transport of substances, of which the transport of oxygen to the tissues, the transport of oxygen and nutrients to the cells, the removal of tissues from cellular activities (such as carbon dioxide produced in the cell). cellular respiration and the conduction of hormones by the body.
In the chart provided below, you can see that the first species belongs to the plant kingdom, and the other three belong to the animal kingdom. The kingdom is a very high level of classification, right below the level of domains. Therefore, organisms that belong to different kingdoms are very distantly related.
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
