Suppose a scientist measures sunflower height six months after groups of sunflowers were planted with and without phosphorus in order to test the effect of phosphorus on sunflower growth. All flowers were grown in a nitrogen-abundant environment. Which of the following would be considered a standardized variable?

Describe an experiment to test whether soil pH affects the growth rate of sunflowers. Include all of the following: hypothesis, predictions, controlled variables, independent variable, dependent variable.
The practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Why would nitrogen-fixing plants be plowed under instead of harvested? a) To increases usable nitrogen in the soil. b) To increase water retention. c) Nitrogen-fixing plants are not a food crop. d) To decrease bacteria in the soil.
What can be concluded from the graph and the description of the experiment? A) fertilizer b is more expensive than fertilizer a B) fertilizer a has a slower growth rate effect on the plants compared to fertilizer b C) plants using fertilizer a were located further away from windows where sunlight was present D) during a four week period, the plants with fertilizer b received more water than the plants with fertilizer a

Crop rotation would allow the farmer to reduce which of the following? a) Planting seeds. b) Watering the fields. c) The use of manufactured fertilizer. d) The burning of fossil fuels by farm equipment.
Discuss the following prompt: In this experiment, we are looking to see how much different types of soil will affect the time it takes for pinto Bean seedlings to germinate out of the ground. The scientific name of a pinto bean is Phaseolus vulgaris. Pinto beans are kind of beans people usually eating, and people commonly use pinto beans in many dishes, such as rice and pasta. Planting pinto beans need many necessary factors, however, I think the type of soil is the most important one to grow it faster. Pinto beans are kind of plants can grow in dark and dry area, so even in dark (less light), they can grow as well. The goal is to determine that soils have different characteristics that can help or hurt plant growth. In order to discover the effects soils have on plant growth, three different soil samples will be used in a controlled study. The samples will vary in consistency, texture, color, location, moisture, and contact with human life to ensure that the samples are…

Name two of the most important factors that will determine the carrying capacity of a desert ecosystem for non-human animals. Are these factors equally important for the desert’s carrying capacity for plants? Why or why not? Explain your scientific reasoning.
Imagine an experiment where I am testing the effects of salt on the growth of corn plants. I set up several treatments where some plants get no salt, some are watered with a 0.05% salt solution, and some are watered with a 0.1% salt solution. I use the same species of plants, the same soil, and the same total amounts of water in my experiment. Every other day I record the height of the plants in cm. What is the independent variable in my experiment? What is the dependent variable in my experiment? What is the control treatment in my experiment? What are three controlled variables in my experiment?
If you were breeding cotton plants to have increased water uptake in dry soils, you could breed plants that contain more amino acids and carbohydrates in the root cells. Why would this be effective and why might crop yield be negatively affected?
The practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Which of the following is not an abiotic factor that affects plants being used in crop rotation? a) NH3 availability b) Soil temperature c) Herbivore density d) Oxygen concentration
If you were to grow a Venus fly trap and provide it with a standard dose of chemical fertilizer, how would the abundance of traps change? Why? Increase because fertilizer helps plants grow larger Decrease because the plant doesn’t need traps to obtain these nutrients anymore Increase because now the plant will have an increased need for animals as food Decrease because the plant knows you will keep on fertilizing it
You are interested in determining the amount of fertilizer your lavender plants need to increase their growth. You get 5 pots of plain soil. You transplant one lavender plant into each pot and measure the height of the plant. You label each pot with letters A-E. A does not get any fertilizer, pot B gets 2mg of fertilizer, pot B gets 4 mg of fertilizer, pot C gets 6 mg of fertilizer, pot D gets 8 mg of fertilizer, and pot E gets 10 mg of fertilizer. For one month you water the plants the same amount and each plant receives the same amount of light. After one month you measure the plants again. The results of the experiment are below. A. Write a testable hypothesis for this experiment. B. Write a prediction based on your hypothesis. C. What is the dependent variable? D. What is the independent variable? E. Do the results support or refute your hypothesis? Results Pot Initial Measurement (cm) Final Measurement (cm) A 5.2…
