Based on this excerpt, summarize the job of mitochondria.
Excerpt: "About the size of pickup trucks from where you're floating, the organelles called mitochondria convert energy from your food into adenosine triphosphate, or ATP, to power biochemical reactions. A typical cell burns through 1 billion molecules of ATP every 1 to 2 minutes."
Answer:
The mitochondria is the powerhouse of the cell!
Explanation:
Ive just memorized this from science last year so I’m very sure, but here’s an explanation:
the excerpt claims “the organelles called mitochondria convert energy from your food into adenosine triphosphate, or ATP, to POWER biochemical reactions. A typical cell burns through 1 billion molecules of ATP every 1 to 2 minutes." Right there in the text, it says the mitochondria uses energy to make into ATP to POWER the cell and biochemical reactions. So there you go! :]

If there are 20 waves in a 5-second time frame, what is the frequency?
If there are 20 waves in a 5-second time frame, the frequency of the wave is 4 Hz.
What are wave and wavelength?A wave is a disturbance that travels through space, carrying energy without transporting matter. Waves can take many forms, such as water waves, sound waves, light waves, and radio waves. In general, waves are characterized by their frequency, wavelength, amplitude, and velocity.
Wavelength is one of the fundamental characteristics of a wave. It is defined as the distance between two consecutive points in a wave that are in phase, that is, they are at the same point in their cycle. For example, in a simple sine wave, the wavelength is the distance between two consecutive peaks or two consecutive troughs.
The symbol used to represent wavelength is the Greek letter lambda (λ). Wavelength is typically measured in meters (m) or some other unit of length. In general, longer wavelengths are associated with lower frequencies and lower energies, while shorter wavelengths are associated with higher frequencies and higher energies.
The relationship between wavelength, frequency, and velocity is given by the formula:
velocity = frequency x wavelength
This formula shows that as the frequency of a wave increases, its wavelength decreases, and vice versa, assuming the velocity remains constant. Similarly, as the wavelength of a wave increases, its frequency decreases, and vice versa, assuming the velocity remains constant.
So, a wave is a disturbance that travels through space carrying energy without transporting matter, while wavelength is the distance between two consecutive points in a wave that are in phase.
Here in the question,
The frequency of a wave is defined as the number of cycles or oscillations that occur in one second. The unit of frequency is hertz (Hz). To calculate the frequency of a wave, we can use the following formula:
Frequency = Number of cycles / Time
In this case, we are given that there are 20 waves in a 5-second time frame. Therefore, the number of cycles is 20, and the time is 5 seconds. Substituting these values into the formula, we get:
Frequency = 20 / 5 = 4 Hz
Therefore, the frequency of the wave is 4 Hz. This means that the wave completes 4 cycles or oscillations in one second.

1. How does the structure of a hard-boiled egg compare to the crust, mantle, and core structure of Earth? What do the egg's layers represent? What might the cracks represent?
2. How do Earth's layers compare in composition and properties with the egg's layers?
3. Can an egg be used as a satisfactory model for Earth's lithosphere (plates) and asthenosphere, plus the rest of the mantle, and the core? How? (Hint: Look very carefully under the shell could the membrane there represent the asthenosphere?)
4. Overall, is the cracked egg a useful model for Earth? Why or why not?
5. Unlike the eggshell sections, Earth's plates move relative to one another. A plate may move away from another plate, or it may move toward it. Earthquakes often result from interactions between plates. Predict what other consequences might result from plate motion.
6. Of the several possible non-egg models of Earth, which do you feel is most appropriate? Why?
7. Of the several possible nonegg models of Earth, which do you feel is least appropriate? Why?
Answer:
2. Earth layers compare in egg layer it is hard on the outside
Explanation:
Answer: for 1 and 2 The inside of the earth is layered something like an egg. Both have a thin, brittle shell. The crust of the earth is broken into pieces, like the cracked shell of a hard boiled egg. The mantle of the earth is like the egg white, and the core of the earth lies in the center, like the egg yolk.
for 3 the shell could also be used because you can crack
for 5 a few things that can happen in the result of plate motion there could be Mt formation or volcano formations.

What happens to the volume and temperature of a liquid and gas when they are placed under pressure in a sealed container? Explain.
The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. This can be easily understood by visualising the particles of gas in the container moving with a greater energy when the temperature is increased.
Hope this helped
The temperature an volume of liquids and gases are dependent upon the pressure of the substance. When liquid and gas particles are placed in a high pressure container then they change their medium from liquid to solid and from gas to liquid.
What is the effect of pressure on gas and liquids?
The pressure law states that for a given constant volume of gas in a sealed container the temperature of the gas in the container is directly proportional to the pressure of the gas. This can be easily understood through visualizing the particles of a gas in the container which is moving with a greater energy when the temperature is increased in the container.
Thus, when the pressure is applied on gas particles, it compresses to liquid and when the pressure is increased on liquid material, it becomes solid. The effect of pressure on solid is negligible as it does not change anything in solid. Thus, if the pressure is applied to a substance its state changes from Gas → Liquid → Solid.

2. A student tested the pH of an unknown solution and the reading
was 13.5. Which statement is true?
A. The solution is a strong base.
B. The solution is a strong acid.
C. The solution is a weak base.
D. The solution is a weak acid.
Since the pH of this unknown solution is equal to 13.5, the true statement is that: A. the solution is a strong base.
What is pH?pH is simply an abbreviation for the power of hydrogen ions and it can be defined as a measure of the molar concentration of hydrogen ions in a particular solution.
This ultimately implies that, a pH can be used to measure and specify the acidity, neutrality or basicity (alkalinity) of any chemical solution.
On a pH scale, a chemical solution with a pH of 7 is said to be neutral, a chemical solution with a pH below 7 is acidic and it's basic (alkaline) when it's pH is above 7.
In conclusion, we can infer and logically deduce that this solution is a strong base because its pH is equal to 13.5.

Please please answer this! explain the kinetic molecular theory ( i don't understand how they explain it in my lesson so if someone could simpfly it for me) worth 30 points
Answer:
Explanation:
Basically, Kinetic Molecular Theory says that gas particles are in constant motion and that they show perfectly elastic collisions.
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision.
So the kinetic molecular theory says that gas particles stay moving constantly and don't lose energy when they run into each other.

Answer:
A force applied at an angle to the direction of motion of an object can cause it to change direction.
Ex: A side wind will cause an airplane to change its direction. It is possible that the object keeps going at the same speed if the force is applied perpendicular to the direction of motion. But the velocity of the object changes.
