I'm going to say a Human.
In one simple statement, Humans have survived all of earth's devastation because of evolution. At one point it is believed that the earth had changing conditions including that some of the food that we hunted in waters became extinct. Then, as lack of food grew, We gained the ability to walk on land. As this happened, we began to adapt to our surroundings, including gaining the ability to walk on two legs and use tools
B. Orbit. The planets orbit the sun, the moon orbits earth, etc.
Increases
Explanation:
Energy increases the speed of the particles in a substance. When energy is added to a substance they gain more kinetic to move.
- When energy is added to solid, the particles begins to vibrate about their fixed point.
- They reach a point where they break lose and the ordered structure of a typical solid collapses.
- They begin to move about freely and flow as in a liquid.
- When enough energy is added, they break their intermolecular attractions and becomes gaseous.
- An increase in energy increases the kinetic energy of the particles of a substance.
- The reverse is the case when energy is removed.

Answer:
f = v / 4L
the frequency of the instruments is reduced by the decrease in the speed of the wave with the temperature.
Explanation:
In wind instruments the wave speed must meet
v = λ f
λ = v / f
from v is the speed of sound that depends on the temperature
v = v₀ ![\sqrt{1+ \frac{T [C]}{273} }](https://tex.z-dn.net/?f=%5Csqrt%7B1%2B%20%5Cfrac%7BT%20%5BC%5D%7D%7B273%7D%20%7D)
where I saw the speed of sound at 0ºC v₀ = 331 m/s the temperature is in degrees centigrade, we can take the degrees Fahrenheit to centigrade with the relation
(F -32) 5/9 = C
76ºF = 24.4ºC
45ºF = 7.2ºC
With this relationship we can see that the speed of sound is significantly reduced when leaving the house to the outside
at T₁ = 24ºC v₁ = 342.9 m / s
at T₂ = 7ºC v₂ = 339.7 m / s
To satisfy this speed the wavelength of the sound must be reduced, so the resonant frequencies change
λ / 4 = L
λ= 4L
v / f = 4L
f = v / 4L
Therefore, the frequency of the instruments is reduced by the decrease in the speed of the wave with the temperature.
