Textbook Question
Chapter 32, Problem 9TYK
Acid rain contains an excess of hydrogen ions (H+). One effect of acid rain is to deplete the soil of plant nutrients such as calcium (Ca2+), potassium (K+), and magnesium (Mg2+). Offer a hypothesis to explain why acid rain washes these nutrients from the soil. How might you test your hypothesis?

The high acidity of the soil means less capacity to bind positively charged ions.
True or False?
Cation Exchange capacity is:
Group of answer choices
a. The amount of cations that can be held by a given mass of soil.
b. Affected by soil texture
c. Affected by the amount of organic matter/Humus in a soil.
d. Affected by the amount of clay in a given soil
e) All of the above
Why fine textured soil hold more water as compared to coarse textured soils?

- Why is it that saltwater cannot be used to irrigate plants?arrow_forwardIt is June in Fresno and the officials at the water district have just reduced your irrigation ration by 26%. In the field, you determine that the water potential in your soil is -1.68 MPa while the water potential of your crop is -1.62 MPa. Question A. Is your crop able to take up water from the soil? Explain. Question B. It is now late August and your soil water potential is -2.10 MPa, fortunately, you have been granted one magic wish in altering the physiology of your crop to increase its ability to take up water, however, you must choose from one of the options below. Fill in the values denoted by the ? as needed, and select the option that will cause the greatest water uptake by your crop. Option Vs (MPa) Vp (MPa) Vw (MPa) -1.90 0.00 -2.59 +0.13 -2.4 -2.09 -2.05 -2.28 +0.17 4.arrow_forwardObservation: I want to know what effect salt has on the growth of grass. So I measure out 3 equal-sized squares of grass out the back of the Green Building. The first square of lawn I water with 5 liters of pure water from a watering can every day. The second square of lawn I water with 5 liters of pure water with 2 grams of salt mixed in, every day. The third square of lawn I water with 5 liters of pure water with 4 grams of salt mixed in, every day. I measure the height of the grass after 14 days and note the following observations. The first square is green and 15 cm high. The second square is greeny-yellow and 6 cm high. The third square is yellowy-brown and looks dead and is only 2cm high. What could we infer about the effect salt has on the growth of grass?arrow_forward
- 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.arrow_forwardWould a soil high in clay but low in organic matter have a higher cation-exchange capacity than a soil low in clay and high in organic matter?arrow_forwardField Capacity occurs at a water concentration when; Group of answer choices a. The water attached to the soil particle can’t be pulled off by the plant. b. When the soil is saturated c) All free water has drained from the soil and that remaining is held to the soil particle against gravitational pull. d) All of the abovearrow_forward
- Do plants need soil to grow? Explain.arrow_forwardAnna conducted an experiment that aimed to determine the deficiency symptoms of tomato plants placed in a hydroponic solution. Six bottles were prepared, and each bottle, except for the positive control, lacked a certain micronutrient. In the positive control, all nutrients were provided. Unexpectedly, the control setup still showed symptoms of micronutrient deficiency. Students later on found out that the relative humidity in the room was very high and transpiration was affected. 1.Explain the appearance of these symptoms in the positive control set-up in lieu of the importance of transpiration? 2.Theoretically, how will thermoregulation of tomato plants be affected if transpiration will not occur 3. Discuss internal factors that could affect the rate of transpiration of the tomato plant.arrow_forwardSCIENTIFIC INQUIRY Acid precipitation has an abnormallyhigh concentration of hydrogen ions (H+).

- Describe the similarities and differences in the absorption and regulation of iron and zinc. What is the mechanism/process that makes phytates affect iron and zinc absorption? How can we enhance the absorption of these sources? Which is the better choice—to eat processed foods that have been enhanced with phytochemicals or to eat natural foods that are rich in phytochemicals? Explain your answer. Look up any uncommon food item in our culture, and find out the nutritional content (what nutrients can this item provide us both macro and micro? How to use it in the diet?)arrow_forward20 (8) a. Which one of the following phenomena is responsible for transportation of food through phloem tissue : a. Mass flow b. Diffusion C. Osmosis b. The reason for my answer is: a. Movement of particles for higher concentration to lower concentration b. Movement of particles of a material to one direction due to gravity C. Movement of particles of a material to direction due to pressure gradient d. Movement of materials as a bulk due to pressure gradientarrow_forwardWhat would likely happen to an herbaceous plant if the soil water content is below optimal range and there is increased ambient temperature?arrow_forward
