Maria and Elena are supposed to help their mom cool some sodas by putting the cans in a big bucket full of ice, except that Maria forgot to fill the ice trays. Elena says that she remembers reading somewhere that hot water freezes faster than
cold water. Maria is skeptical. She learned in her science class that as a liquid is hotter, its molecules move more quickly.
Since the hot water molecules have to further reduce their speed than cold water molecules to become ice, Maria thinks it
will take more time for hot water to freeze than for cold water. The girls decide to conduct a science experiment to
determine if it is faster to make ice cubes with hot water or with cold water.
Now, answer the following questions about the process they used to reach their conclusion.
Ask a Question
1. What is the question that Maria and Elena want to answer when doing the experiment?

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
