A disease was caused by a bacterium; you want to produce a biological product to kill this bacterium. Which product you have to
makvit [3.9K]

Answer:

The product that must be produced to kill a bacterium —which causes a disease— is an antibiotic, which through biotechnology can investigate the structure of the bacterium and synthesize the chemical formula needed to produce antibiotics in high amounts.

Explanation:

Antibiotics are specific medicines for the treatment of infectious diseases, produced by bacteria. <u>Antibiotics can kill bacteria and prevent their replication</u>.

If a disease is produced by bacteria, the product that is necessary to kill those microbes is an antibiotic, for which biotechnology is useful.

By using biotechnology —a branch of biology that uses technology as a research and development tool— it is possible:

  • <em>Know the structure, functions and behavior of pathogenic bacterial strains. </em>
  • <em>Create chemical formulas -antibiotics- that serve to effectively eliminate bacteria, and cure infectious diseases. </em>
  • <em>The synthesis and production of antibiotics on a large scale, allowing their sufficient availability for use.</em>

2. Antigens can trigger an immune response. Explain if this is a specific or a nonspecific defense.
masya89 [10]

This is a specific response because in order to fight antigens, white blood cells, the most important cells of the immune system, must produce large, Y-shaped proteins known as antibodies to fight these invaders. This is a type of specific defense (as I have identified antibodies as specific defenses is the chart above).

DENIUS [597]

Answer: Commonly known as deadly nightshade, belladonna, devil's cherry, and dwale. One of the most toxic plants found in the Western Hemisphere, all parts of the plant contain tropane alkaloids – as do those of its equally deadly sister species A.

Explanation: It contains several toxic alkaloids including coniine and is poisonous to humans and livestock. Consumption of just a small amount of any part of the plant can cause respiratory paralysis and death. Poison hemlock, with its purple-blotched stems, can cause paralysis if ingested.
