What are the horticultural advantages of producing plants by cuttings rather than from seeds? Can you think of any disadvantages?
Answer:
Propagating a plant by cuttings will allow you to keep the special characteristics of that plant. Plants grown from seed will often be different from the parent plant and from each other. Propagating a new plant via cuttings avoids the difficulties of propagating by seed.

Why have scientist devised a system of comparative weights for atoms rather than using actual weights
Answer:
Because of multiple reasons:
Explanation:
Atoms are way too small to weigh.They couldn't use weight, they would have to use mass.Some atoms are free-floating, because they are the air.If they even made a scale that measured each atom, it would also catch the air atoms as well, unless they had a vacuum chamber, but even then, no one can make a perfect vacuum, space is not even a perfect vacuum...Hope this helps.

Bellwork: of the locations of earthquakes over the past 10 years were plotted on a world map, which of the following would be observed?
A. Earthquakes occur with the same frequency everywhere on Earth.
B. Earthquakes generally occur along the edges of tectonic plates.
C. Earthquakes most frequently occur near the middle of continents.
D. Earthquakes do not seem to occur in any consistent pattern.
Answer: B.
Explanation:
It's not A, because earthquakes happen at different magnitudes depending on how the plates shift beneath them.
It's not C, because tectonic plates are scattered among the earth.
It's not D, since the pattern of earthquakes are dependent on the shifts of tectonic plates.
It's B because tectonic plates are the reason earthquakes happen. Everytime they shift or move, an earthquake occurs. There may be some earthquakes that are not near tectonic plates but the majority are, which is why the question uses the word "generally occur."

Why doesn't a gummy bear grow as much in sugar water as it does in normal water?
Answer:
In comparison to the gelatin molecules in the candy, salt or sugar ions in water are significantly smaller. Water molecules go to a location with more solute to balance things out due to osmosis. The problem is that the water is trapped inside the candy and cannot escape. Because the Gummy Bear can't get any smaller, it keeps the same size.
