Antagonsitic effect/interaction/response
In order to combat antiobiotic resistance, and to possibly enhance the activity of antibiotics, they are sometimes used in combinations during treatment. However, three possible responses or effects can manifest.
First is antibiotic synergy, where the combined effect of the antibiotics enhances the activity/potency of the treatment compared to when the antibiotics are administered singly.
The effect is also distinguished from another type of response, which is additive effect, where the combined effect of the antibiotics is more or less equal to the combined activity/potency of each of the antibiotic when applied singly. Antibiotic synergy results in even greater enhancement of the activity of the combined antibiotics compared to additive effect.
Lastly, there is the antagonistic effect or response, where the combined effect of the antibiotics results in the weakening of the potencies of the antibiotics relative to the combined (additive effect) potencies of each of the antibiotics.
(A) A large amount of nitrates in the water :)
Most metamorphic processes take place B. a few kilometers below Earth’s surface.

Metamorphism is the change of minerals or geologic texture in pre-existing rocks without the protolith melting into liquid magma. Metamorphism often occurs on two scales: contact and regional. Contact metamorphism occurs locally in areas adjacent to igneous intrusions or in areas that are in contact with hot water known as hydrothermal fluids. Whereas regional metamorphism occurs over much larger areas such as rising mountain ranges, large igneous intrusions can form and warp overlying strata increasing the pressures above the intrusion. Regional metamorphism usually produces foliated rocks such as gneiss and schist.
There are other ways that metamorphic rocks can form, Dynamic metamorphism. Dynamic Metamorphism also occurs because of mountain-building. The huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared.
Metamorphic rocks form when increased heat and pressure force physical changes in the crystalline structure of an existing rock. Under the right conditions, any type of rock can become a metamorphic rock including igneous rocks, sedimentary rocks, and even other metamorphic rocks. Therefore metamorphic processes result due to intense heat and high pressure below the Earth's surface.

Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
Answer:
The respiratory system is necessary for an organism's body to live because it introduces oxygen-rich air, which is needed to perform vital functions, while at the same time promoting the elimination of carbon dioxide.
Explanation:
Oxygen (O₂) is necessary for life because it participates in the process of cellular respiration, a mechanism that allows the oxidation of glucose to form energy in the form of ATP.
The respiratory system is made up of a set of organs that carry air into the body and facilitate gas exchange, i.e. the entry of O₂ into the blood and the elimination of potentially harmful carbon dioxide (CO₂).
This exchange of gases occurs in structures called pulmonary alveoli, whose surface is located in relation to the pulmonary capillary vessels.
- The entry of air into the lungs brings O₂ to the alveoli, which will diffuse into the pulmonary capillary for the process of hematosis or oxygenation of the blood.
- CO₂, a product of metabolism, leaves the capillary to the alveoli, to join the air that will be expelled during expiration.
Both O₂ and CO₂ require a transport molecule in the blood, red blood cell hemoglobin, which binds the gases and allows them to be transported to and from the tissues.
