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.

Answer:
A familiar example of homeostatic regulation in a mechanical system is the action of a thermostat, a machine that regulates room temperature.
Explanation:
Answer:
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level.

Digestive bacteria and humans - Human beings have what is often called "good" bacteria in
their digestive systems. This "good" bacteria exists in order to help the human to digest food
Some foods cannot be digested entirely: so, when these foods are consumed, the bacteria
in the digestive system feed on those foods.
The bacteria stay alive.
The human gets help with the process of digestion.
predation
mutualism
competition
commensalism
Answer:
commensalism
Explanation:
Gut bacteria in particular are very important for digestion in humans and other species. ... In return, the bacteria get a steady supply of food. Commensalism: In commensalism, one organism benefits while the other organism neither benefits nor suffers from the interaction.
The human gets help with the process of digestion is commensalism
What is commensalism?Commensalism deals with the long-term biological interaction where members of one species gain benefits while on the other hand, those of the other species neither benefit nor harm. Gut bacteria should be very important for digestion in humans and other species.

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.

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.
Answer:
The difference is the louder the sound the bigger the waves and your ears collect the sound waves and brings it to you brain

i’m just a little confused can someone explain ?
Basically, there is a presentation of types of food and the amount of those foods over 50 years in this graph. This means the graph is showing amounts of certain foods over the time period. I'm guessing that basing off of the the previous text you're just noting a change in the breaks of birds based off of the diet available to them at certain times. The adaptations and natural selection will explain the changes because due to certain limited and available foods the diet of the birds change.
