- In words, describe the differences you see for each organism grown at 30 C or 37 C (i.e., amount of growth, color, etc)denitrification occure in wetland soil because - 1 - The top thin layer of soil is oxidized and the soil layer below is reduced. 2 - The top thin layer of soil is reduced and the soil layer below is oxidized 3 - The top thin layer of soil is oxidized and the soil layer below is also oxidized. 4 - The top thin layer of soil in reduced and the soil layer below is also reducedWhich of the following is not a soil structure types? Group of answer choices True False a) Granular, b) Crystalline c) Angular blocky d) Columnar/prismatic e) Platy
- Trace the route of the nutrients NO 3- carried by river runoff to a seagrass ecosystem. Indicate the specific process involved (e.g., nitrification, denitrification, etc.) and the chemical form (e.g., NH +, NO -, etc) at each step of transformation. Write your (short) answers in the numbered blanks below each illustration.An experiment tested the hypothesis that soil pH affects the color of flowers produced by plants. A researcher measured the pH of the soil beneath 1,000 hydrangea plants naturally occurring outside, in a park, and recorded the colors of the flowers on each plant. The researcher found that when the soil pH was about 5.0, hydrangeas produced 99% blue flowers, and when the soil pH was around 7.0, the plants produced 98% red flowers. part a: Which of the following would be an abiotic factor in the plants’ environment? Group of answer choices A. daylength B. pollinators C. insects that eat the plants D. flowers E. birds part b: Did the researcher show that soil pH caused the color of the flowers? Group of answer choices A. Yes, because the researcher included 1,000 plants in the study. B. Yes, because the results very strongly showed the relationship between flower color and soil pH. C. Yes, because the researcher had a clearly stated hypothesis. D. No, because there…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…

- According to Atterberg, between the ________________ and ______________ limits, a soil is in a plastic state.A farmer has noticed that his soybean plants produce more beans in some years than others. He claims to always apply the same amount of fertilizer to the plants but he suspects the difference in crop yield may have something to do with the amount of water the crops receive. The farmer has observed that the soybeans on his farm usually receive between 0 to 0.5 inches of water per day, but he is unsure of the optimal amount of water with which to irrigate. Question: state a research question that will directly address the farmer’s problem.A scientist investigating into the quality of soil in Potsin area determined the soil bulk density using graphical approach. Five soil samples from the farm were sampled and their respective masses and volumes determined in the laboratory. The masses (g) of soils sampled and their respective volumes (V) are shown in the table below. A. Plot a graph of mass (g) against volume (Cm^3). B. Deduce from the graph the mathematical expression relating mass and volume of soil sampled. C. From the graph determine the bulk density.
