Gastric juice  is a thin strongly acidic (pH 1 - 3 ) almost colorless liquid secreted by the glands in the stomach lining. It is made acidic by one of its constituents namely hydrochloric acid. It is because of its acidic nature that gastric juice can be  so corrosive to the lining of the duodenum.

The integrity of the inner lining of the (mucosa) of the duodenum depends on a careful balance of the "aggressive" factors (such as acid) and "defensive" factors (such as mucus) which helps to protect the delicate surface lining.

Disruption of this balance caused by too much acid (or weakened defense ) can result in erosions or ulcers .

Which of these ideas correctly states a relationship between the practice of conserving energy and the effect that it has on peo
Bess [88]

The idea that correctly states a relationship between the practice of conserving energy and the effect that it has on people's health is: Energy conservation promotes less air conditioner use and warmer homes (option B).

<h3>How is energy conserved?</h3>

To conserve means to use judiciously or wisely, therefore, energy conservation refers to the effort made to reduce the consumption of energy by using less of an energy service.

The conservation of energy helps to reduce workload on mechanical devices such as air conditioner, cooker etc.

Therefore, the idea that correctly states a relationship between the practice of conserving energy and the effect that it has on people's health is: Energy conservation promotes less air conditioner use and warmer homes.

SSSSS [86.1K]

Answer:

The virus will transfer the DNA encoding cholera toxin to the next bacteria it infects, which will make that bacteria cholera-causing.

Explanation:

The process described in this question is a kind of gene transfer in bacteria called TRANSDUCTION. Transduction is the transfer of fragments of DNA from one bacterium to another via a virus called bacteriophage.

As stated in this question, the virus (bacteriophage) infects a cholera-causing bacterium. The bacteriophage moves from lysogenic cycle to lytic cycle and includes some pieces of the bacterial DNA, which encodes information for making the cholera toxin, in its own genome.

This means that the cholera-making toxin DNA is now a part of the virus's genome and hence, will transfer it to the next bacteria it infects in a process called TRANSDUCTION. This will make that bacteria a cholera causing bacteria.
