Answer:

A. Replicate the experiment to see whether the results are similar

Step-by-step explanation:

According to Oxford dictionary, an experiment is a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.

It is best practice in science that an experiment is to be carried out three times before conclusion is made on the experiment and the results published.

An experiment is repeated three times due to the fact that a two-thirds (66%) probability of averaged results are more accurate than a single experiment.

An experiment is replicated (repeated) to establish a relationship between experiment results.

Replication lets scientists see patterns and trends in their experiment results.

A replicated experiment gives a scientist an affirmation on the results and gives more validity to the process and the results.

Vilka [71]

Answer: 100 grams

Step-by-step explanation:

From the question, Claude purchased a container of peanuts that weighs 4 kilograms. We can convert this to grams and it'll be:

= 4 × 1000 grams = 4000 grams.

Taryn purchased a container of peanuts that weighs 4,100 grams. The difference will then be:

= 4100 grams - 4000 grams

= 100 grams

Taryn bought 100 grams more.
