What are the horticultural advantages of producing plants by cuttings rather than from seeds? Can you think of any disadvantages?

Answers

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.

You will get greater uniformity (clones) of your plants. The plant will reach maturity at an earlier age. Disadvantages of propagating stem cuttings are: You will get a lack of genetic diversity and you may potentially increase Insect and Disease weakness in the new plant.

Should we start doing genetic testing to determine if someone is a good candidate to be a firefighter, or police officer? Why or why not?

Answers

Great question! In my opinion anyone can do anything as long as they have the qualifications, take John for example. Let’s say he is a random guy from New York with no genetics in the police department. If john takes the tests and training and qualifies as a police man, it shouldn’t matter what his genetics are. I think testing however is a good idea due to the fact it narrows down the participants who in theory should be good at it etc. And separates the strong from the weak. Hope this helps!

Why doesn't a gummy bear grow as much in sugar water as it does in normal water?

Answers

Salt molecules are much smaller than sugar molecules, so more of them will dissolve in water.

Hope this helps<3

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.
