The temperature and the amount of milk in each glass are shown: Glass A: 20 grams of milk at 10 °C Glass B: 50 grams of milk at 80 °C Glass C: 20 grams of milk at 50 °C Glass D: 50 grams of milk at 80 °C Which statement is correct?
Answers
Answer:
A. 20 grams of milk at 10°C
Explanation:
Since we refrigerate milk, it would be cooler than the room temperature, which standard norm is 25°C. So the milk has to be colder than the room temperature. Therefore, our answer is A.
Answer: A is the correct answer
Explanation:
The temperature of room temperature is more than that and you need to keep it colder, hope this helped!

Is there a relationship between CO2 levels rising and heavy precipitation? If so, what is it?
Answers
Answer:
Explanation:
Yes, there is a relationship between rising CO2 levels and heavy precipitation. As the concentration of CO2 in the atmosphere increases, it leads to a warming of the Earth's surface due to the greenhouse effect. This warming, in turn, causes an increase in the rate of evaporation of water from the Earth's surface, including from the oceans, lakes, and rivers.
This increased evaporation results in more water vapor in the atmosphere, which can lead to heavier precipitation events, including more frequent and intense rainstorms, snowstorms, and other forms of precipitation. This is because warmer air can hold more moisture, making it more likely to produce heavy rainfall.
In addition, the warming of the Earth's surface can also lead to changes in atmospheric circulation patterns, which can further increase the likelihood of heavy precipitation events in some regions.
Overall, the relationship between rising CO2 levels and heavy precipitation is complex and can vary depending on the specific location and other environmental factors. However, there is evidence to suggest that as global temperatures continue to rise due to rising CO2 levels, heavy precipitation events are likely to become more frequent and intense in many parts of the world.
Answer: Yes there is a direct relationship between CO2 and heavy precipitation. Rising in CO2 means increasing the temperature in the atmosphere which causes more water vapor evaporates into the atmosphere and which causes high rainfall or precipitation.
Explanation: Increased atmospheric CO2 levels are causing plant stomata to close, allowing plants to hold more water in their stems, reducing transpiration, and possibly impacting tropical rainfall patterns in varying ways depending on region.
What is an ellipse please help)
Answers
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

Do you think a moving skateboard has energy? Why or why not?
PLEASEEEEEE HURRY
Answers
Answer:
"Yes," a moving skateboard has energy.
When the skater seems to be in motion or throughout a movement, the potential energy converts itself into the kinetic form of energy, and then it becomes potential energy again.
Furthermore, somewhere after every movement, the same skateboarder was around a similar height, — in other words thus every time it is equally powerful.
The response is thus the right one.

How could you turn steam into a liquid?
A. Using a magnet
B. By removing thermal energy
C. By evaporating it
D. By adding thermal energy
Answers
Answer: B
Explanation:
CONDENSATION When steam is cooled, it releases thermal energy and turns into its liquid state. This process is called condensation.
A is incorrect because using a magnet has nothing to do with a phase change.
C is incorrect because the steam cannot be evaporated
And D is incorrect because if you add thermal energy, the particles would move really fast and possibly turn into plasma.

The area where the land meets the sea is called the coastline. This area can have different physical features depending on its location. Some common features of coastlines are beaches, cliffs, bays, harbors, estuaries, and dunes. Beaches are made up of loose particles like sand and gravel that are deposited by the sea.
In some areas, the shoreline may consist of a wide, sandy beach, while in others it may be rocky and steep.
In general, the shoreline is where the land transitions to the sea, and it is often marked by the presence of waves, tides, and other oceanic phenomena.

Answer: 2 and 4
Explanation:
The way to find if a chemical change happened is if something major like a new substance is created, or if it is mixed with another chemical. If the structure of the chemical has changed, it is a chemical change. Gas, sound, or light as well as a temperature change is not affecting the structure of a chemical substance, meaning it is 2 and 4 which doesn't have anything that could cause its chemical structure to change.

Which pairs are analogous structures? - Examples of analogous structures range from wings in flying animals like bats, birds, and insects, to fins in animals like penguins and fish. Also in short term it means comparable in certain respects, typically in a way which makes clearer the nature of the things compared.
