figure out what goes in the blank

A number of compounds in the atmosphere have the effect of warming the Earth's surface.
Scientists have found that recent increases in the abundance of the compound (*Blank*)
in the atmosphere have been the most important factor in causing recent global warming trends.

Answer:

Water vapor. The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapor increases as the Earth's atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect.

Explanation:

Which is most likely a chemical property?
A) Oxidation state: the charge an atom has if it was bonded ionically to other atoms Different oxidation states indicate different abilities to bond with other atoms.
B) Melting point: the temperature at which a solid turns into a liquid. Different substances have different melting points.
C) Density: the amount of a substance that fits in a certain volume. Different states of matter of the same substance can have different densities.
D) Conductivity: the ability to transfer electrical charges. Conductivity is different in different substances.

PLSSSSSSSSSS Which best explains why a person can tell the difference between a whisper and a yell?

Sound waves turn into chemical signals that indicate certain sounds.
Different vibrations in the ear cause the brain to interpret different sounds.
The fluid in the cochlea picks up electrical signals for the intensity of sound.
The eyes see what is making the noise and help the brain process the sound.

HELPPPP ASAP!!!!! These are the last onesss

can someone explain i’m a bit confused??

In an experiment, equal amounts of heated water and soil were left to cool down. The initial and final temperatures of each were recorded. A partial record of the temperature is shown.

Experimental Record
Substance Initial Temperature Final Temperature
Water 27 °C 24 °C
Soil 27 °C ?

Which statement about the final temperature of soil is correct?

It will be less than 24 °C as soil loses heat relatively faster than water.

It will be less than 24 °C as water loses heat relatively faster than soil.

It will be more than 24 °C as it takes relatively longer to change soil temperature than water temperature.

It will be more than 24 °C as it takes relatively longer to change water temperature than soil temperature.

The what tells how many protons or electrons there are in an atom

choices:
A.atomic mass
B.atomic number
C.electrons

Read the following sentence:

"When you look at a basketball, what are you seeing?"

Why might the author have started the passage with this question?

a
to give the reader an object to visualize before examining the role of light
b
because the main idea of the passage is about basketball
c
because the author wants to use the example of basketball to explain electromagnetic radiation
d
to show how important the color orange is to electromagnetic waves

Describe what happened with Mendel crossed purebred tall pea plants with purebred short pea plants.

You overheard a classmate in the hallway say the following statement.
???: it gets warmer when you move up the atmosphere because you are getting closer to the sun.”
Do you agree or disagree with him.
If possible could you explain why you agree or disagree it could help me a lot because I’m kinda confused.

Only answer if you have an answer to the question. Thank you.
