The majority of bacterial species on earth have not been successfully cultivated. true or False

Biology
1 answer:
Valentin [98]3 years ago
5 0

Answer:

True

Explanation:

The bacterial cultivation refers to growing the bacterial species for exploitation or use. But the humans are not able to cultivate the majority of the bacterial species present which could be accounted for many reasons.

The bacteria can mutate very easily through the exchange of genetic material. Some bacterial species cannot be isolated.  New bacterial species are discovered in less period of time and some species fail to grow on the growth medium due to lack of information.  Till now only one percent of bacterial species have been cultivated.

Thus, true is correct.

From your genetics lab, Agrobacterium tumefaciens gram-positive bacterium was used during your experiment on genetic manipulation of a corn plant

Rhizobiaceae is a family of bacteria that includes Agrobacterium tumefaciens. Gram-negative and aerobically growing, these bacteria don't produce endospores. The cells have one to six peritrichous flagella and are rod-shaped and motile. Cells can exist alone or in pairs and range in size from 0.6 to 1.0 m by 1.5 to 3.0 m.

Agrobacterium tumefaciens is a gram-negative bacterium that causes tumors in plants through horizontal gene transfer. In a variety of plant species, Agrobacterium tumefaciens has been widely exploited as the primary agent in the generation of transgenic plants. A soil phytopathogen called Agrobacterium tumefaciens naturally infects plant wound sites and causes the disease known as crown gall by the transfer of (T)-DNA.

How do consumers MOST BENEFIT from perfectly competitive undifferentiated market compared to a monopolist competition?
marysya [2.9K]

The way in which consumers<u> </u><u>most benefit </u>from a perfectly competitive undifferentiated market compared to a monopolist competition is that this kind of market will produce lower prices.

An increase in the<u> number of choices</u> as well as the<u> amount of marketing</u> can be considered consumer benefits of a perfectly competitive market in that the increased competition will force companies to expand into new products and invest more towards marketing in an effort to attract consumers, thus making it easier for said consumers to find their desired product.

on the other hand, a monopoly is when a <u>single controlling entity </u>has ownership of<u> all or almost all of the producing companies for a specific product</u>, causing an absence of competition and thus eliminating the need for competitive pricing. Though the benefits mentioned before are good for consumers, the greatest benefit is in the reduction in prices caused by a competitive market, allowing much greater access to a wider variety of goods for all of the economic classes.
