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.

What is the central idea of the article Elephants Attack as Humans Turn Up the Pressure?
docker41 [41]

Answer: c) Researchers think that stresses created by humans are the reason behind increasing numbers of elephant attacks.

Explanation:

The aforementioned article by National Geographic shows that the higher number of elephant attacks on humans are as a result of human activities that are placing stress on elephants.

Humans are increasing in population and as a result need more land for farming. This is resulting in a shrinking habitat for elephants who then encroach on human farms and are killed for it which leads to some elephants having Post Traumatic Stress Disorder and killing other humans which then continues the cycle.
