in what way does agriculture, lumbering, housing, industrial development, and highway construction affect erosion

1 answer:

5 0

Here is what I'm guessing:

In agriculture, crops and trees will have their roots firmly in the ground which will prevent erosion and vice versa with lumbering. Any kind of construction and building will have land be cleared so there will be room for development. This, in turn, will disturb and continue to erode the land.

VLD [36.1K]

Answer:

See the answer below.

Explanation:

Antibiotic-producing bacteria are generally known to have a mechanism that enables them to be resistant to their own antibiotics. The mechanism that enables them to be resistant to their own antibiotic depends largely on the mode of action of the antibiotic substance.

Some of the popular mechanisms used by bacteria to counter their own antibiotic substance include a mutation in the target gene, production of enzymes that inactivate the antibiotic compounds, or efflux of the compounds.

In the case of Streptomyces griseus, the inactivity of streptomycin has been linked with the production of a phosphatase inhibitor that prevents streptomycin from getting access to the target site. Hence, the organism is not harmed by its own antibiotic.

Which of the following are among the most common second messengers?

frosja888 [35]

Answer:

The correct answer would be calcium ion and cAMP.

Secondary messengers refers to the intracellular signaling molecules which pass the signals from the receptors located on the surface of the cell to the target molecule present within the cell.

The secondary messengers can be classified into three major class:

Cyclic nucleotide for example cAMP (cyclic adenosine monophosphate), cGMP (cyclic guanosine monophosphate)
DAG (diacylglycerol) and IP₃ (inositol triphosphate)
Calcium ions (Ca⁺⁺)

Hence, from the given options, calcium ion and cAMP would make the correct choice.
