Answer:
Bacteriophages are attaching to bacterial cell wall and injecting genetic material.
Explanation:
Bacteriophage:
A bacteriophage (bacteria eater) is a type of virus that infects bacteria. Bacteriophages are composed of genetic material (DNA or RNA) enclosed in a protein shell or capsid.
Following are steps of bacteriophage infection:
- Bacteriophage attaches to cell surface receptors on the surface of the bacterium.
- Depending upon the type of phage, the bacteriophage either injects its DNA or RNA into the bacterium or enters as a whole. In this image, the bacteriophage T4 is represented which injects its genetic material into the host cell.
- The phage's genetic material hijacks the cellular machinery of the host and replicates itself within the host.
- After replication, the phages burst open the bacteria cell and are released. This is called the lytic cycle of bacteriophage infection.
- In another type of infection cycle, called the lysogenic cycle, the bacteriophage genome gets incorporated into the host genome, known as a prophage. This prophage lies dormant.
* The second step of the infection cycle is pictured here.
The right answer is True.
Sustainable agriculture is the application to agriculture of the principles of sustainable or sustainable development as recognized by the international community in Rio de Janeiro in June 1992. It is a system of agricultural production that aims to ensure sustainable production of food, wood and fiber respecting the ecological, economic and social limits that ensure the maintenance over time of this production.
Sustainable agriculture aims to reduce the environmental impact of the sector. It is in particular an agriculture that better protects the biodiversity, the water and the soils that are necessary for it and which uses it better through the auxiliaries of agriculture and the ecosystem services. And also by creating more per capita wealth per unit of production, on a more equitable basis. These principles are based on the recognition that natural resources are not infinite and that they must be used wisely to ensure long-term economic profitability, social well-being, and respect for the environment (all three are pillars of sustainable development).
Answer:
B. There are no producers in the benthic zone that relay on photosynthesis.
Explanation:
There are no producers present in the benthic zone because benthic zone is located in higher depth where there is no sunlight so no photosynthesis occurs there. We know that photosynthesis only occurs in the presence of sunlight, if there is no sunlight then there is no photosynthesis occurs and as a result no producer can survive there so we can conclude that there is no producers present in the benthic zone .
