As a couple of people have pointed out, human hearing ranges from 10 Hz to 10,000 Hz, but as people get older and as they damage their hearing by listening to very loud music, firing guns without ear protection, working in very noisy environments or having other physical damage, that upper end drops off. At 64 yrs old, with a long history of a target shooter before we thought about ear protection, and after many years as a rock and roll disk jockey.<span>

For the answer to answer above, <span>O - Ordered structure </span>
<span>H - maintain Homeostasis with the environment </span>
<span>S - respond to Stimuli from the environment </span>
<span>A - Adaptation to the environment </span>
<span>R - ability to Reproduce </span>
<span>G - Grow and develop over the period of their life </span>
<span>E - transform Energy from the environment </span>
<span>Remember, all life is made from cells (this is not a "process" that living things carry out, but rather a property of life itself).</span>

Answer:
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases in a planet's atmosphere radiate energy in all directions.
Answer:
Explanation:
Hello there!
In this case, according to the required half-reaction, we start by setting it up from bismuth (V) oxide ion to bismuth (III) ion:
Thus, next realize that the oxidation state of Bi in BiO3^- is 5+ because oxygen is 2- (-2*3+x=-1;x=-1+6;x=+5), so we obtain:
Thereafter, we realize three water molecules are needed on the right in order to balance the oxygens and consequently 6 hydrogen atoms on the left to balance hydrogen:
Now, since the balance is is basic media, we add six molecules of hydroxide ions in order to produce water with the hydrogen ones:
Then, we accommodate the waters to obtain:
Best regards!
