1. Sequence Order the path of a sound wave
from when it is produced by a source until
it is interpreted by the brain
Answer:1. The sound waves arrive at the pinna (auricle), the only visible part of the ear.
2. Once the sound waves have passed the pinna, they move into the auditory canal (external
acoustic meatus) before hitting the tympanic membrane (eardrum).
3. Once the sound waves reach the tympanic membrane, it begins to vibrate and they enter
into the middle ear.
4. The vibrations are transmitted further into the ear via three bones (ossicles): malleus
(hammer), incus (anvil), and the stapes (stirrup). These three bones form a bridge from
the tympanic membrane to the oval window.
5. Once sound passes through the oval window, it enters into the cochlea in the inner ear.
6. Hair cells in the organ of Corti (within the cochlea) are stimulated which in turn
stimulates the cochlear branch of the vestibulocochlear nerve.
7. The cochlear nerve then transmits electrical impulses to the auditory region of the brain
in the temporal lobe.

Which of the elements shown has an atomic mass of 20 amu?
A) A
B) B
C) C
D) D
The elements shown have an atomic mass of 20 amu is Neon.
What is atomic mass?
The atomic number of an atom is its total number of protons and neutrons.
Neon has an atomic mass of about 20 this isotope contains 10 protons and 10 neutrons.
Actually, Neon would be listed as having an atomic mass of about 20.18 because of a mixture of isotopes.
Z= Atomic number the number of protons in the nucleus which defines the element.
In this case, Z=10 and this means neon but there are also 10 neurons in the nucleus of the major isotope which gives it 20Ne.
Hence, option D is the correct answer.

If a disease strikes the snake population in the food chain shown, what will happen to the populations of hawks?
The population of hawks would decrease
The population of hawks would increase
The population of hawks would stay the same.
The population of hawks will increase and then decrease.
Answer:
The population of hawks would decrease cause the snake is decreasing
Explanation:
although i would think hawks could eat rabbits but it doesn't ask you that so its haws decreasing
Answer: The population of Hawks will decrease.
Explanation: When the population of one species decreases suddenly, as when a disease strikes the population, the populations higher in the food chain also decrease due to a loss in food supply. In this case the hawk population decreases because there are suddenly fewer snakes to eat. The species below the diseased species in the food chain increase because there are fewer predators. In this case, the rabbit population increases because there are fewer snakes to eat them.

How many particles are present in a 56.9 mole sample of calcium hydroxide?
Answer:
Particles? Calcium hydroxide does not exist as discrete molecules, but as a network solid. The only way you would have separate particles, is if the calcium hydroxide was dissolved in a boatload of water. Ca(OH)2 is not all that soluble in water. Nonetheless, assume a lot of water, enough to dissolve 56.9 moles.
Ca(OH)2 --> Ca2+ + 2OH-
56.9 moles Ca(OH)3 x (3 moles ions / 1 mol Ca(OH)2) = 170.7 mol ions

Answer:
Radiant energy to chemical energy
Explanation:
Got it right on edge 2021
One energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.
What is energy transformation?Energy transformation is the process in which one form of energy converted into another form of energy.
What is photosynthesis process?Photosynthesis process is defined as the process in which plants makes their own food by using the carbon dioxide, water and sunlight in the chlorophyll.
The balanced chemical equation of photosynthesis process is
6CO2 + 6H2O → C6H12O6 + 6O2.
Since, it have 6 atoms of carbon, 12 atoms of hydrogen and 18 atoms of oxygen on both side. So, it is balanced.
Since, sunlight which it take is in the form of radiant and convert it into chemical energy.
Thus, we concluded that the energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.

If two vectors combine in the same direction what mathematical operation would you use to
find the resultant vector?
Answer:
The head-to-tail rule is used to sum two vectors pointing in the same direction. (Vectors in the same direction are called collinear). The sum vector is slightly moved out of its correct position so that you can see it. For now, to determine if two vectors have the same direction look at a picture or use geometry.

The period of time needed for a radioisotope to lose one-half of its activity is known as that isotopes
Explanation:
The radioactive scattering technique is called radioactive degradation. For each radioactive isotope, the natural radioactive cycle is special and is determined by a period of time termed a half-life. One half-life was its time needed to experience radioactivity for half of both the radioactive nuclei.

How many protons and neutrons are in an atom of B-13?
Answer:
6 protons and neutrons
Explanation:
Most representative metal atoms tend to gain enough electrons to attain a stable noble gas (octet) configuration.
True or False
Answer:
False
Explanation:
Non- metals tend to gain electrons easily, metals tend to lose electrons easily
For example, oxygen, a non-gas, when it is an ion, has the option to lose 6 electrons to become like helium, or gain 2 electrons to become like the noble gas neon. However, it becomes like neon for 2 reasons.
A. As a general rule, atoms lose/gain the LEAST amount of electrons.
B. Oxygen is a nonmetal, therefore, to become like a Noble Gas, it would gain, as non-metals usually would, 2 electrons.

Answer:
410 nm
Explanation:
when an electron falls from ni=6 to nf=2 , a photon of wavelength 410 nm is emitted.
When an electron falls then the wavelength of the electromagnetic radiation emitted is = 410 nm.
What is electromagnetic wavelength?
When The Electromagnetic wavelength directs to the measured distance between the trough or crest of each adjacent wave generated by the electromagnetic disturbance.
When the wavelength of electromagnetic radiation is comparable to the de Broglie wavelength of its quantum (photon).
Now we are Showing that the wavelength of electromagnetic radiation is comparable to the de Broglie wavelength of its quantum (photon).
Therefore, when an electron falls from ni=6 to nf=2, a photon of wavelength 410 nm is emitted.
