Hi
I wish they give you options....
I believe the answer is : A dis-conformity <span />
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.
Answer:
Soil salinity can be reversed, but it takes time and is expensive. Solutions include improving the efficiency of irrigation channels, capturing and treating salty drainage water, setting up desalting plants, and increasing the amount of water that gets into aquifers. Mulches to save water can also be applied to crops.
Explanation: Hope this helps

</span> :D Now that you've seen this you will get a perfect A on the test ^.^
Pass this on to someone's answer and replace my answer with the answer you get.
HAVE FUN and GOOD LUCK :P
