Answer 1

Experimental approach- Plant three plants of the similar type, in the same pot having same soil in three at dissimilar locations. Put one on the windowsill, another on a coffee table in the center of the living room, furthermore one outside. Observe them over a time of 7 days, while ensuring they get the equal quantity of water as well as concentration each day at the same time. Dependent and independent variables- Independent variable: plant location Dependent variable: type of plant used.

Control: The plant which grows outside, since we are acquainted with, that is where it will get the most contact to light. collection of data- Use a ruler to assess the growth of the plants on each day. Presentation of data -Present pictures of the locations at the accurate time when you are measuring as well observing the plants to show considerable change. Present a chart with the days and what has been measured in plant each day. Analysis of data- Compare the control plant, that is in the outdoor with the one on the windowsill which must be growing more than the one which is on the coffee table in the center of a living room and check if the lack of sun really made a disparity.

Experimental approach- Cheking two meals a day for a period of so as to observe the ingestion of fatty foods and healthy foods. Fatty lunch on day 1 while testing blood pressure. On day 2 having a healthy lunch while again testing blood pressure. Conduct this test with dinner also so as to ensure blood pressure is taken honestly after the end of the meal. Ensure that before the meals blood pressure is checked and recorded to see the disparity. Dependent and independent variables- Independent variable: fatty as well as healthy foods Dependent variable: blood pressure. Controls - The blood pressure at what time when the subject has not taken any foods, while ensuring blood pressure is recorded before every meal. collection of data- Recording and observing track by the help of journal of what variety of foods are taken so as to see if there was a difference in that and if there was more of a noteworthy alteration with certain foods more than others. Presentation of data- Presenting data with a journal by list of foods taken as well a chart to explain what blood pressure was when food was taken and to show a variation or correlation of blood pressure compared to food taken. Analysis of data- analysis of data by looking at the ingredients of the foods while relating that to the increase, decrease or constant blood pressure and the outcome of foods on an individual’s blood pressure.
