Answer:
Mitochondria
Explanation:
The enzymatic reactions of the cellular respiration begin in the cytoplasm, but most of the reactions occur in the mitochondria.
Answer:
Cellular respiration is the multi-step process that creates energy from nutrients and food molecules. It begins in the cytoplasm of the cell, with the mitochondria functioning as the main organelle where the rest of the process continues and finishes.

Is tomato juice a solution? state a reason for your answer.
Answer:
yes tomato juice is a solution. because it is homogenous mixture and it's ingredient dissolve in water.
Solutions are made of a solute and a solvent. Tomato juice is solution since it contains the tomato pulp and water which can be mixed well.
What is a solution?A solution is a combination of a soluble or insoluble salt and a solvent like water. There are homogenous solutions and heterogenous solutions. In the homogenous solutions the solute is completely soluble in the solvent and both exists in one phase.
In heterogenous solutions, the solute form a different phase from the solvent and appear immiscible. The components can be mixed well using stirring methods.
Tomato juice is made by the tomato pulp and water. The pulp and water is mixed well to form the juice and it appear to be one solution
Therefore, tomato juice can be considered as a solution.

how can you test a sample of soil for acidity or alkalinity
Answer:
Scoop a soil sample into a fresh container, add 1/2 cup of water, and mix. Then, add 1/2 cup of baking soda. If the soil bubbles or fizzes, the soil is acidic. The reaction you're seeing is the result of acidic soil coming into contact with an alkaline substance (baking soda).

What are some differences between a main sequence star and a red giant?
Answer:
Some notable differences between a main sequence star and a red giant are its sizes and color. Red Giants tend to typically be, well, red. The output of a red giant is so much greater than that of a main sequence. A red giant is the last stage of a main sequence star's life. Another difference is what occurs inside the star. Main sequence stars fuse hydrogen together in order to keep gravity from imploding the star, while red giants run short of hydrogen and fuses helium.

What is light?
Light, often known as visible light, is electromagnetic radiation that falls within the region of electromagnetic wave or spectrum that the human eye can perceive.
White is a mixture of all seven colors found in the white light spectrum, including Violet, Indigo, Blue, Green, Yellow, Orange, and Red. This visible spectrum has a wavelength of 400 to 700 nanometers. When an object appears to be a particular color, such as red, it signifies that it is projecting the wavelength of red light (620 to 750 nanometers) while absorbing all other wavelengths. Furthermore, because light is a kind of energy, the more light a thing consumes, the more heat it consumes.

At 6 atmosphere pressure, the volume of a gas is 1200 ml. What pressure is
required to reduce the volume of a gas to 200 ml without changing the
temperature?
Answer:
36 atmExplanation:
The pressure required can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the required pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
From the question we have
[tex]P_2 = \frac{6 \times 1200}{200} = \frac{7200}{200} = \frac{72}{2} \\ [/tex]

7. Calculate the average atomic mass of bromine. One isotope of bromine has an atomic mass of 78.92amu and a relative abundance of 50.69%. The other major isotope of bromine has an atomic mass of 80.92amu and a relative abundance of 49.31%.
Answer:
Average atomic mass = 79.9 amu.
Explanation:
Given data:
Average atomic mass of Bromine = ?
Atomic mass of 1st isotope = 78.92 amu
Relative abundance of 1st isotope = 50.69%
Atomic mass of 2nd isotope = 80.92 amu
Relative abundance of 1st isotope = 49.31%
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (50.69×78.92)+(80.92×49.31) /100
Average atomic mass = 4000.45 + 3990.16 / 100
Average atomic mass = 7990.61 / 100
Average atomic mass = 79.9 amu.

Answer:
0.2 moles
Explanation:
The number of moles of aluminum for 1.204 x 0²³ atoms of aluminum is 0.2 moles. Hence, The correct answer is Option (A)
What is the mole concept ?
Mole is defined as the amount of the substance containing the same number of discrete entities (atoms, molecules, ions, etc) as there are atoms in a sample of pure 12C weighing exactly 12g.
The number of particles present in one mole of any substance = Avogadro Number = 6.023 x 10²³.
Formula to calculate Mole when number of particles is given ;
n = given number / 6.023 x 10²³
n = 1.204 x 10²³ / 6.023 x 10²³
n = 0.2 moles

At 303 K, the volume of a gas is 30.0 ml. At constant pressure, what is the new
volume of the gas if the temperature is decreased to 283K?
Answer:
V₂ = 28 mL
Explanation:
Given data:
Initial temperature = 303 K
Initial volume = 30.0 mL
Final temperature = 283 K
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 30.0 mL × 283 K /303 K
V₂ = 8490 mL.K / 303 K
V₂ = 28 mL
