The microorganism responsible for the common cold is a group of viruses known as the Influenza Viruses.

As they are viruses, it is important to remember that they cannot be treated with antibiotics. Antibiotics are useful only against bacterial infections.

The best treatment for viruses is the body's own immune system. However, for dangerous strains, vaccines are developed. These "teach" the immune system to recognize the virus in question and destroy it rapidly.

Answer:

The most common myths are:

- C0vid2019 vaccines cause autism  

- C0vid2019 vaccines may modify your DNA

- C0vid2019 vaccines are unsafe

Explanation:

The most common myths associated with C0vid2019 vaccines are:  

1- C0vid2019 vaccines may cause autism: In 1998, Andrew Wakefield and colleagues published a controversial study in the Lancet where they suggested that the measles, mumps, and rubella (MMR) vaccine may cause autism in some children. However, it has been showed that this study was based on erroneous statements and therefore this publication was retracted.

2- C0vid2019 vaccine may modify your DNA: it has been suggested that vaccines based on viral vectors (e.g. adenoviruses) and mRNA vaccines may modify the DNA of cells. This statement is false because these technologies cannot alter the DNA sequence. These vaccines are based on the production of an mRNA sequence that is translated into a viral protein (spike protein) which triggers an immune response

- C0vid2019 vaccines are unsafe: some people believe that C0vid2019 vaccines are unsafe because they were developed quickly. However, this statement is false because all vaccines (including C0vid2019 vaccines) need to follow rigorous safety standards to be approved by governmental agencies (i.e., they approved all clinical trials).

Drag the labels to their appropriate locations on the concept map below to explore the links between antibiotic resistance, bina
Nataliya [291]
The correct sequence is:
a) Antibiotics: These antimicrobial drugs used to treat and prevent bacterial infections.

b) Antibiotic resistance: This sort of resistance occurs when bacteria are fully developed into the body and are able to defeat the drugs which designed to kill them. When certain bacteria become resistant, the antibiotics are unable to fight them, and hence they increase and affect the body.

c) Binary fission: Binary fission is a sort of asexual reproduction in prokaryotes such as bacteria. It is found in unicellular eukaryotes like Amoeba and Paramecium.
d) Conjugation: It is the transfer of genetic material between bacterial cells by the direct or bridge-like connection between cells.

e) Mutations: is a permanent alteration in the DNA sequence resulting in a gene, such that the sequence differs from the sequence found in human beings.

f) DNA replication: is the biological process that occurs in all living organisms to produce two identical replicas of DNA from a DNA molecule.

g) Genetic recombination: During this process, offspring are produced with the combinations of traits that are different from the traits found in either parent.

h) Genetic variation: It’s the variation in the DNA sequence in each of human genomes, making every human being unique in terms of hair color, skin color or the shape of their faces.<span>
