Answer:

Option A, GV law

Explanation: The laws of gravity (actually called "Newton's Law of Universal Gravitation") are laws in the field of classical mechanics that tell us the behavior of gravity.

now the simplifications are:

a) GV Law

This is fine because with this method you will always remember that these are laws.

b) L of G

This could mean different things, it is not advisable to use this type of abbreviations, since you can read it and not remember what L or G means.

c) VGlity

I really don't understand what this means, this is not a good option.

d) Newt gravity.

This option is also good because you can remember Newton's name, but it is a bit longer than the first option.

So, the option that has more information and is also shorter is the first option of the GV law, so that would be the correct option

Answer:

1. It reduces the probability of sampling bias.

2. A random sample will be more representative of the whole population.

3. Allows the researcher to determine the efficacy of the fertilizer.

Explanation:

Selecting a simple random simple from a large population is a widely used method in science. Researchers select a random sample so every individual, in this case seedling, has an equal chance to be selected.

Therefore, it is an accurate method that, although is not free from errors, avoids or reduces the probability of sampling bias. Selecting a truly random tomato seedling will be more representative of the whole population of seedling instead of selecting carefully a seedling that already has specific or desired characteristics. Hence, this random sampling will allow the researcher to determine the efficacy of the fertilizer.
