because only surface water can be used for human purposes
because the amount of freshwater is unlimited and should be used freely
because water is continuously cycled from land to the atmosphere and back
because once we use up a source of freshwater it is gone forever
Answer:
Water is continuously cycled from land to the atmosphere and back.

Glycine (C2H5NO2) is added to a growing peptide chain containing methionine (C5H11NO2S) and alanine (C3H7NO2). Which of the following peptide chain orientations best displays the growing chain and peptide bond between the amino acids?
Answer:
First Image
Explanation:
Amino acid order is NCC (Nitrogen, alpha carbon with R group attached, and carboxy group).
If we start with methionine, then we write its nitrogen, then alpha carbon and then carboxy and then alanine's nitronge, alpha, carboxy, and end with glycine nitrogen, alpha and carboxy.
I have labelled the "R" groups to show amino acids. First is methionine, then alanine and then glycine.
Damage to which spinal nerve(s) might produce the inability to breathe?
Damage to the phrenic nerve might produce the inability to breathe.
What do you mean by Nerves?Nerves may be defined as a pile of axons outside the central nervous system, surrounded by a sheath of connective tissue to form a cordlike structure.
The phrenic nerves are responsible for the movement of the diaphragm during the process of breathing. This movement of the diaphragm plays a crucial role in the inhalation and exhalation of air.
Therefore, damage to the phrenic nerve might produce the inability to breathe.

In the electrolysis of aqueous nabr, which substance is first produced at the anode?
NaBr is a soluble salt. When you dissolve the solid in water it will first separate the íons: Na+ interact and is surrounded by about 6 water molecules, and could be now represented by [Na.6H2O]+, still a positive íon; the Br- will also separate from the Na+ and interact with water molecules (typically 4–6), forming the [Br.nH2O]-, a negative íon.
What is produced at the anode in aqueous electrolysis?Oxygen is produced (from hydroxide ions), unless halide ions (chloride, bromide or iodide ions) are present.
In that case, the negatively charged halide ions lose electrons and form the corresponding halogen.
Thus, this the answer.

what parts of the food web are affected when an orangutan become endangered?
Answer:
On average, 2,000 to 3,000 orangutans are killed every year. While exact orangutan population counts are always a challenge – estimates put current counts between 50,000-65,000 orangutans left in the wild.
At this rate of loss, many experts believe orangutans could be extinct in the wild in less than 50 years.
Never before has their very existence been threatened so severely. Economic crisis combined with natural disasters and human abuse of the forest are pushing one of humankind’s closest cousins to extinction.

Transitions between biomes do not have to be sharp and sudden, which means that different biomes can share characteristics is a true statement.
The transition between two biomes is called an ecotone. The ecotone may have the characteristic of the two biomes in which it borders. It may have plant species from both biomes.
In addition to dividing ecosystems into aquatic and terrestrial, we can also speak of transitional ecosystems (or transitional biomes), which, as the name implies, are in transit between the first two, or rather, represent the passage from one to the other.
