Marina86 [1]

Answer: False

Explanation:

Pathogens can be transmitted in many ways. It can spread by direct contact, indirect contact, or by vectors.

The mode of transmission can be skin contact, airborne particles, touching a surface, bodily fluids, touched by an infected person.

The mode of transmission can be vector that carries disease and helps in disease transmission.

. If a person comes in contact with this same virus years later, what does our body produce to get rid of or kill the virus
borishaifa [10]

If a person comes in contact with this same virus years later, our body produces antibodies to get rid of or kill the virus

Explanation:

When a person is infected by a virus, the infected person's body develops antibodies as an immune response to act against the virus. Antibodies are produced as part of humoral immunity.

Antibodies work by neutralizing the viral activity, agglutination,  phagocytosis or by complement system.

Antibodies are protein compounds which can recognize the invading pathogens and attack them.

Antigens or viral proteins in the virus leads to the production of antibodies in the host's body.

The specific antibodies triggers innate immune response upon detecting specific viral antigens when infected and will help the body to get rid of  or kill the virus.

What evidence suggests that RNA appeared before DNA? ribozymes, catalytic RNA, play pivotal roles in modern cells ribosomes are
mote1985 [20]

Answer:

<em>The evidence that suggests  RNA  appeared before DNA is the fact that RNA can act as an enzyme to self-edit their own genetic code. </em>Moreover, it has the ability to store genetic information, while transfer and ribosomal RNA have the ability to translate genetic information into proteins.

Explanation:

RNA has a great capability as a genetic molecule, it once had to carry on hereditary process on its own. It is absolutely sure that RNA was the first molecule of heredity. However, a single stranded RNA is rather unstable and easily damaged by enzymes. By essentially multiplying the existing RNA molecule, and using deoxyribose sugar instead of ribose.

<em>The DNA evolved as a much more stable form to pass genetic information with accuracy.  It shows a biological evolutionary purpose .</em>
