When presented with the question “does plant food x have an effect on the production of tomatoes? ” develop a hypothesis to answer this question and then design a small controlled experiment to test the hypothesis.

My hypothesis: If Plant Food X is used on a tomato plant, then production rate will increase.  

Experiment: Gather 2 tomato plants of the same age and height. Make two groups, an experimental group (a tomato plant with using Plant Food X) and a controlled group (a tomato plant without use of fertilizer).

For about one week, give both plants the same amount of water, humidity, sunlight, and air temperature. after a week measure the number and height of the tomatoes produced. Once the week is over, Gather the information in a table and compare to hypothesis.

sorry, but you do not have posted the diagram.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
