Answer:
Although the question is incomplete, missing options are
- In 1997, they reduced their water consumption.
- In 1996, they planted more trees to curb water pollution.
- In 1994, they used only bottled water for drinking purpose.
- In 1995, they complained about foul odor and taste in water.
Correct option: <em><u>In 1996, they planted more trees to curb water pollution.
</u></em>
Explanation:
Among given options, a clear trend of nitrate level can be seen. <u>Initially, the nitrate level increased in water in first two years (1994 and 1995) and then it decreased significantly</u>.
From the conditions given in the question, the most probable answer is B the plantation effect (<u>phytoremediation</u>). During phytoremediation, <u>plants take up nutrients including nitrate</u> from the water via roots. This nitrogen is then used for the growth and development of plant body mass (e.g. amino acids). As more plants were growing in later years, higher reduction of nitrate was seen. Resultantly, in 1997, the concentration of nitrate was dropped to 7.3 mg/L.
The other options are not correct due to following reasons.
A. There is no information on water consumption in the question
C. There is no information on people's behavior on drinking water lifestyle.
D. Nitrate in the water cannot be smelled or tasted.
The black coffee, with a pH of 5 has a hydrogen ion concentration of 1 x 10^-5 mol/L. The tomato juice, with a pH of 4, has a hydrogen ion concentration of 1 x 10^-4 mol/L.
By taking the difference between the two respective concentrations, we can compute how much greater the concentration of hydrogen ions in the tomato juice is compared to the coffee.
Difference = (1 x 10^-4 mol/L) - (1 x 10^-5 mol/L)
Difference = 9 x 10^-5 mol/L
Thus, the tomato juice has a concentration of hydrogen ions that is 0.00009 mol/L greater than the the concentration of hydrogen ions in the black coffee.

The "Nucleus" contains the genetic information of the cell in the form of deoxyribonucleic acid (DNA) or chromosomes and thus, controls cell growth and multiplication. It is also the site of DNA replication (formation of an identical copy of DNA).
While the "Golgi apparatus", or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.

Answer:
increased activity of phagocytes in an inflamed area
Explanation:
An inflammatory response is the way the body defends itself against attacks by microbes, physical or chemical agents. In other words, this is how organisms defend and inhibit damage from attacks. The inflammatory response allows high phagocyte activities in the inflamed area. Phagocytes are immunity-related cells that attack foreign and invasive substances, bacteria and dead cells.
