Answer:
B. Microbes may produce unique proteins useful in genetic research
Explanation:
Biodiversity refers to the diversity of living beings present on Earth. The biodiversity is a very important component of the ecosystem as these living organisms are interlinked with each other. Therefore, the loss of biodiversity will affect the ecosystem.
When we look at the biodiversity a layman considers the living organisms which can be seen with eyes but the diversity also exists at the level of the micro-organisms.
The man-made activities are not only harming the macroscopic but also microscopic organisms. The microbes play an important role in our life like these days they are used by the scientific community to study the genetic and related fields like molecular biology. The microbes produce proteins that are consumed by humans.
Thus, Option-B is correct.
A stop enzyme is used in protein synthesis to stop tRNA from carrying messages from the DNA to the ribosome.
True
False

Explanation:
Legionnaires disease is a type of lung inflammatory disease or pneumonia, which is caused by infection from the bacteria Legionella bacterium.
Legionella bacterium can be spread by inhalation from water or soil. People with weakened immune systems are most susceptible as are smokers. Untreated legionnaires disease can progress to a fatality.
Some of the questions to ask of a victim or of surviving relatives include;
1) Any visits to swimming pools?
2) Source of drinking water?
3)Any visits to fountains?
4) Contacts with victims and their personal belongings?
5)Is any relative or victim immunocompromised? Do they have diseases that might lower their immune response?
6) Are they smokers?
Answer:A. Protists B. Bacteria C. Animals D. Plants E. Fungi F. Archaea
Explanation:viruses are small non-living particles that contains hereditary materials.viruses attack cells of other organisms such as plants , bacteria ,archaea etc.
Viruses are acellular and contains either DNA or RNA.they cannot synthesis protein as they lack ribosomes ,so they use the ribosomes of the cell they have invaded to synthesize they proteins they need.
A virus usually has a central core surrounded by an outer protein coat called capsid.
Viruses can reproduce only within the living host cells and they are specific to the type of cells they attack.they attack plants through insect vectors or through openings on the plants.
Viruses can affect bacteria by injecting their nucleic acids through the cell wall and into the bacteria cell.such viruses are called bacteriophages.
