Which is one factor that adds to the greenhouse effect?
a decrease in the amount of dust in the atmosphere
a decrease in the amount of water on Earth’s surface
an increase in gases in the atmosphere that absorb heat
an increase in the amount of solar radiation that reflects into space
Answer:
C
Explanation:
Edge 2022 trust the process
Knowing about the greenhouse effect we have that what intensifies this effect is an increase in gases in the atmosphere that absorb heat.
What is the greenhouse effect?Greenhouse effect is a natural atmospheric phenomenon responsible for the maintenance of life on Earth. Without the presence of this phenomenon, the temperature on Earth would be very low, around -18ºC, which would make the development of living beings impossible.
Thus, the main cause of the greenhouse effect is industrialization. Due to this process, the burning of fossil fuels has intensified in recent centuries. The main products of the combustion reaction of these reagents are the gases mentioned above as the main ones for the greenhouse effect.

In the malate-aspartate shuttle, _____ is reduced to _____ in the cytosol. oxaloacetate; malate aspartate; malate malate; aspartate malate; oxaloacetate aspartate; oxaloacetate
The malate-aspartate shuttle enables oxidative phosphorylation by allowing electrons to be moved across the inner membrane in the mitochondrion during glycolysis in eukaryotes.
In this malate-aspartate shuttle, oxaloacetate is reduced to malate in the cytosol.
During this biochemical system process, the cytosolic malate dehydrogenase which is the primary enzyme present in this shuttle system catalyzes the reaction of oxaloacetate and NADH to produce malate and NAD in the cytosol. This system enables oxidative phosphorylation in eukaryotes.Learn more: https://brainly.com/question/17216910
Convert 4.0 moles of krypton into liters of krypton.
Answer:
4.0 moles of krypton converts to 89.6L.
Explanation:
To convert moles to liters, remember that at standard temperature and pressure (STP), 1 mole is equal to 22.4 liters. Multiply your mole value - in this case, 4.0 - by the molar volume constant, 22.4L, to convert moles into liters. 4.0 x 22.4 is equal to 89.6, thus your answer is 89.6L.
We can check this by dividing 89.6 by 4.0, which will give us the molar volume constant 22.4L, proving that this answer is correct.
A chemist heats a fixed amount of gas in a sealed glass container. Which law is the chemist most likely
investigating? (1 point)
O Charles's law, by seeing how changes in temperature affect the volume of the gas
O Charles's law, by seeing how changes in temperature affect the pressure of the gas
O Gay-Lussac's law, by seeing how changes in temperature affect the volume of the gas
O Gay-Lussac's law, by seeing how changes in temperature affect the pressure of the gas
The chemist is most likely investigating Gay Lussac's law. To study the changes in temperature affect the pressure of the gas when a fixed amount of gas is heated in a sealed glass container. Therefore, option (D) is correct.
What is Gay Lussac's law?Gay-Lussac's law states that when the volume of the gas is kept constant the pressure of a gas is directly proportional to the absolute temperature.
The mathematical expression of Gay Lussca's law can be written as follows:
P/T = k
It can be also represented as the pressure being directly proportional to the temperature of the gas.
P ∝ T (where V volume of gas is constant)
or
[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2}[/tex]
Where P₁ and T₁ are the initial temperature and pressure of the gas. The P₂ and T₂ are the final temperature and pressure of the gas.
As the container is sealed on heating the volume of the gas will not change. On increasing the temperature the molecules of the gas acquire more and more kinetic energy. So the pressure of the gas will increase.
Therefore, the chemist is investing the Gay-Lussac's law by noticing how changes in temperature affect the pressure of the gas.

What will a wave look like with high amplitude and long wavelength?
A. Tall and narrow
B. Short and narrow
C. Tall and wide
D. Short and wide
Answer:
A tall and narrow A tall and narrow
Explanation:
Answer:
A. Tall and Narrow
Explanation:
The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. But high amplitude waves tend to be short spent and tall narrow linings.

Which of the following are phase changes? (Select all that apply.)
melting
gases
sublimation
reactions
Answer:
- melting
- sublimation
Explanation:
A phase change is a, well, change between phases. Solid to liquid. Gas to solid. Etc. Gases is a phase, but not a change. Reactions is a change, but not a phase change. This leaves us with melting (solid to liquid) and sublimation (solid to gas).

Answer:
Plant cells and animal cells are both eukaryotic cells. They both have a nucleus, Golgi complex, endoplasmic reticulum, ribosomes, mitochondria, cytoskeleton and cell membrane. Only plants cells have a vacuole, cell wall and chloroplast, while animal cells have cilia, centrioles and lysosomes which plant cells don't usually have. Because of their cell walls plant cells are in rigid rectangular shapes while animal cells have looser round shapes. The main difference in their functions is that animals don't produce their own food while plan cells do.

Would results of solubility of sugar dissolving in water change if a person used a different solute?
Answer:
If a solute is a solid or liquid, increasing the temperature increases its solubility. For example, more sugar can dissolve in hot water than in cold water. If a solute is a gas, increasing the temperature decreases its solubility. For example, less carbon dioxide can dissolve in warm water than in cold water.
