The Scientist Experiments

by Stacy Lewis



(1) Scientists study the world around us. (2) One way that scientists do their jobs is by conducting experiments. (3) The experiments that scientists conduct are like tests that they perform. (4) Experiments help scientists learn how things happen in our world and why things happen in our world. (5) For example, a botanist, a type of scientist who studies plants, a botanist would perform experiments related to plants.

(6) Here is an example of a basic, meaningful experiment that a botanist might conduct. (7) The materials required are a seed, a pot of soil, and water. (8) First, the scientist plants a seed in the soil. (9) She then places the pot on a window sill, or a similarly sunny place where it can soak in the sun. (10) She waters the seed every day, watches for changes. (11) And then she dutifully records what happens. (12) After thirty days, she measures both the plant's height and weight, as well as also measuring the number of leaves it has grown.

(13) Next, she repeats the same steps with another seed, excepting that she only waters the second seed once a week this time. (14) Again, she takes records of the plant's growth and makes the same measurements. (15) Then she compares her results, hoping to figure out the impact of daily watering on plants. (16) Does regular watering make plants healthy and tall, or does it not matter? (17) Her results can help to reveal the answers to such queries.

Answer 2

The correct answer is A. every day, watches for changes, and dutifully records what happens

Step-by-step explanation:

In general terms, the purpose for revisions is to improve a sentence, text or paragraph, usually because these have problems in punctuation, spelling, use of transitions, etc. In the text presented, which is about Scientist Experiments, the sentences to be revised are sentence 10 and 11 "She waters the seed every day, watches for changes. And then she dutifully records what happens".

The main issue with these sentences is the use of punctuation as, according to grammar it is not necessary to separate two sentences if the conjunction "and" is being used, instead the period should be replaced by a comma to create a longer sentence. Additionally the use of the word "then" is not necessary as the coordinating conjunction "and" implies one action is linked to the other. Therefore, the best revision is "every day, watches for changes, and dutifully records what happens".
