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…

About 200 years ago, Jan Batista van Helmont wanted to know where growing plants get the materials necessary for increase in size. He planted a tree seedling weighing 2.2 kilograms (5 pounds) in a barrel filled with 90 kilograms (200 pounds) of soil and then watered the tree regularly. After 5 years, the tree had gained almost 75 kilograms (164 pounds), and the soils weight was unchanged. He incorrectly concluded that the tree had gained all of its additional weight by absorbing water. How did the tree really gain most of its weight?

- The following figure depicts the outline of a large fairy ring that has appeared overnight in an open meadow, as viewed from above. The fairy ring represents the furthest advance of this mycelium through the soil. Locations A-D are all 0.5 metres below the soil surface. Which type of organisms made this structure (it wasn't a fairy!)? What is mycelium? Explain in one sentence each. Which location (A-D) most likely indicates the oldest part of this organism?

In this experiment you had two treatments - one with soil bacteria present, the other with soil bacteria absent. To determine how soil bacteria affected plant growth, you then measured plant height after 1 month. You find that plants grow taller in the treatment with soil bacteria compared to the treatment with no soil bacteria.

- An experiment is conducted to determine the effect of classical music on the growth rate of marigolds (flowers). Two groups of plants are grown from seed in identical soil types, exposed to identical light conditions, and given the same nutrients. Group A is in a quiet atmosphere. The plants in group B provided with the same atmosphere, except that classical music is played for twelve hours daily in this area. The scientist measures the plants in both groups each day and records the data. In experimental design, Group A is known as.* experimental group control group non-experimental group O quasi-experimental grouparrow_forwardThe two pictures below are two soil profiles that typically form in under different types of vegetation, but can also occur relatively close together: 20 40 First, using morphological clues learned in lab, define what these two soil orders are.

- Describe a hypothesis explaining the mutual relationship between plant roots and mycorrhizae present in the soil.arrow_forwardThe Irish potato famine was an important historical event that occurred in the 1840’s. The Irish were generally low income, and relied entirely on a particular variety of potato, known as "lumpers”. This strain of potato was susceptible to a rot caused by Phytophthora infestans. This led to wide-spread potato spoilage, which devastated the food supply, and ultimately caused many deaths. What would have been an effective strategy to avoid the Irish potato famine? Plant a more diverse mix of potatoes. Use antibiotics on the potatoes to protect from the rot. Expand cropland to increase the total number of potatoes grown. Use fertilizers, crop rotation, and irrigation to improve potatoes crop yields.arrow_forwardSimpLENI will be competing in a Lugaw Cooking Competition in May. She will be using onions as a special ingredient and garnish in her recipe. She then planted onions in two soil treatments labelled as ANGAT and UNITY. After a week, SimpLENI noticed that her onions in ANGAT increased in number compared to that of onions in UNITY. She then hypothesized that the soil treatments affected the cellular division in the roots of onions contributing to the difference in yield. To prove this, SimpLENI prepared longitudinal sections of onion root tips. Support SimpLENI in her experiment and win the competition by answering the following questions:arrow_forward

They are now interested in determining whether the moss must be alive to prevent nitrogen loss, or do dead moss have the same effect? Arrange the following steps in the correct sequence to test this hypothesis. 1. Add herbicide to the soil of the experimental plot of mosses. 2. Apply water equally to the experimental and control plots. 3. Measure initial soil nitrogen contents of control and experimental plots. 4. Quantify nitrogen loss from the soil of control and experimental plots. 5. Establish two identical plots of moss; one as a control, the other as the experimental treatment.
