A researcher was interested in finding out whether talking toplants was related to plant growth. To test this idea she used 20plants where all 20 plants had the same amount of food, waterand sunlight. She randomly assigned the 20 plants to 1 of 2groups: she talked to 10 of the plants for 1 minute/day; shetalked to the other 10 plants 10 minutes/day. Every day for onemonth the researcher measured the height of the plants.What is the Independent variable and the Dependentvariable in the example above?

In experimental studies, values of independent and dependent variables are determined to explain and…

Which of the following biological factors (see biotic factors) were observed to have affected your plants? Describe what was the effect on your plants in 1-2 sentences
Jack and Jill are curious about the factors that affect plant growth. They perform several experiments using pea plants -The leaves of the pea plants that received too much water turned yellow. observation - Jill decided that 5 hours of indirect sunlight gave optimum growth conclusion -Jack gave the pea plants a controlled amount of water each day. Experiment -Jill thinks that too little sunlight will affect plant growth. hypothesis please help me with the next part (a) Identify one variable (other than water and sunlight) that could be tested. (b) Write a hypothesis using this variable. (c) Design an experiment to test this variable.
a botanist wants to see how different colored light waves influence the growth of pea plants. she puts the same number of seeds into three identical pots with the same kind and amount of soil. she then gives them the same amount of water every 3 days for the length of the experiment. one pot is placed into a dark windowless closet. another part is left on the window sill, and the third is placed under a lamp with a green bulb. she records the height of each plant every day for 3 months what is the independent variable in this experiment.
Urkle decided he wanted to test the effects of watering his plants with cold coffee. For a week he watered one group of plants cold coffee. He ignored the other group of plants. Urkle has no idea what might happen to plants that receive coffee. What is wrong with Urkle's experimental design? If Urkle wants to test the effects of cold coffee on plant growth, he should water his control group with cold water. If Urkle wants to test the effects of cold coffee on plant growth, he should water the plants in the other group with Dr. Pepper. If Urkle wants to test to test the effects of cold coffee on plant growth, he should water the plants in the other group with hot coffee. If Urkle wants to test the effects of cold coffee on plant growth, he can ignore the control group as long as he makes sure both groups get the same amount of sun.

A scientist put in a pot in which he put 200 pounds of dirt that he dried in a furnace.He added rain water and planted a willow tree weighing 5 pounds, He then planted the pot it in the garden & placed an iron lid punched with many holes to allow water in.At length, after 5 years the tree weigh 169 pounds and 3 ounces. Dried the earth it weighed almost 200 pounds (less about 2 ounces). So the willow tree gained 164 pounds of wood, bark and roots. Where did the tree get the mass from?
