How does copper contamination in soil affect plant growth in an endangered plant?You haveOne greenhouse with three tables100 seeds (10 each from 10 plants: assume each seed is viable)unlimited pots, soil, copper, etc.ConsiderHow will you set up your experiment?How many samples (per treatment, per measurement)?What will you measure (leaf area, number of leaves, shoot height, shoot biomass)?
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?
Experiments usually have several controlled variables. These are variables that must be kept constant in all parts of an experiment. For example, if an experiment is testing the effect of sunlight on the growth rate of 5 seeds, the only variable that should change should be the amount of sunlight. All other variables should remain the same to ensure that sunlight is the only aspect affecting the results. The other variables, such as soil type, amount of water, type/amount of fertilizer, are the controlled variables. Looking back at the simulation experiment on the meteorite, describe two variables that should have been controlled.

Imagine you sampled a field that is 60 m X 130 m to see how many white clover plants are growing there. You used the same size quadrant as used in the video (0.5 m X 0.5 m). Please remember that m stands for meters. You took 10 quadrant samples and found a total of 8 white clover plants.
Two groups of tomatoes were grown under laboratoryconditions, one with humus added to the soil and one acontrol without humus. The leaves of the plants grownwithout humus were yellowish (less green) compared withthose of the plants grown in humus-enriched soil. The bestexplanation is that(A) the healthy plants used the food in the decomposing leavesof the humus for energy to make chlorophyll.(B) the humus made the soil more loosely packed, so waterpenetrated more easily to the roots.(C) the humus contained minerals such as magnesium andiron needed for the synthesis of chlorophyll.(D) the heat released by the decomposing leaves of the humuscaused more rapid growth and chlorophyll synthesis.
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…

3. Make a table that best matches the following set of animals and crops with the soil unit most suitable for the crop or animal use, given the following information: Agricultural use: Walnuts do best with deep, well-drained soil. Lettuce can produce excellent crops in soils that have a good topsoil (A horizon) but a somewhat dense subsoil (B horizon) that has slow permeability. Wheat can produce very high yields without being irrigated if there is a high water table (in other words, a shallow depth to the water table). Goats eat a wide range of forage on rangelands, even in relatively steep mountainous areas.
