SOMEONE HELP I AM IN DESPERATE NEED AND WILL DO ANYTHING A scientist saw that her tulip plants in the front yard were growing taller than the tulips in the back yard. She thought that maybe the amount of water was making the difference so she planted new bulbs in an unused portion of her backyard and separated it into three areas of equal size: A, B, and C. She watered the tulips in area A the required amount as stated by the fertilizer used, 5 cups per day. She watered area B with 10 cups of water per day and area C with 15 cups of water per day. She planted 10 bulbs in each group and used the same fertilizer throughout the entire garden. She collected results for 1 month and recorded the height of the plants in inches on Sunday of each week. Her data is presented below.

Day 7 – A 2 inches, B 3 inches, C 4 inches, Day 14 - A 5 in, B 8 in, C 4 in, Day 21 –A 9 in, B 13 in, C 5 in, Day 28 – A 13 in, B 20 in, C 3 in.

G. Define control group.

H. List the control group.

I. What conclusion can you draw from the data? How is it supported with the data?

J. List and explain one way you would improve this experimental setup to make it more reliable and valid with supporting data.

A. Define the independent variable.

The independent variable is a variable in an experiment or research that affects the dependent variable and gets manipulation or change in the study.

B. List the independent variable(s).

Amount of water each group of plants receives.

C. Define dependent variable.

A dependent variable is a variable that depends on the independent variable and is measured to see the effect of manipulation in the independent variable.

D. List the dependent variable(s).

Height of the plants

E. Define controlled variables.

Controlled variables are the variable that remains the same and did not change in the experiment to avoid any other effect than independent variables on subjects.

F. List three controlled variables.

equal size of land

amount of fertilizer

Number of plants in each group

Period of time

G. Define control group.

The control group is the group of subjects that did not get treatment as the experimental group receives for the comparison of the result and ensuring if the experiment works.

H. List the control group.

A group of plants that receives 5 cups of water is required in a normal condition.

I. What conclusion can you draw from the data? How is it supported with the data?

The amount of water affects the height of plants but up to an extent.

one centimetre is equal to 0.01 metres

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
