Microorganisms in the soil decompose waste as a source of energy for growth and release carbon dioxide (CO2). Scientists have observed that as soil temperatures increase (up to 25°C), the amount of CO2 released into the atmosphere from the soil increases. Which explanation about how environmental factors affect the growth of microorganisms is BEST supported by this observation? Group of answer choices An increase in soil temperature decreases microorganism growth because the rate of decomposition decreases. An increase in soil temperature increases microorganism growth because the rate of decomposition increases. An increase in the amount of CO2 in the atmosphere from the soil increases microorganism growth because the rate of decomposition decreases. An increase in the amount of CO2 in the atmosphere from the soil decreases microorganism growth because the rate of decomposition increases.
Answers
Answer:
An increase in soil temperature increases microorganism growth because the rate of decomposition increases.
Explanation:
An increase in soil temperature increases microbial activities and the activity of extracellular enzymes that degrade polymeric organic matter within the soil. An increase in the soil microbial activities means that the decomposition rate and microorganism growth would increase. Increase in the activity of extracellular enzymes that degrade polymeric organic matter within the soil also means that more carbon dioxide would be produced and released into the atmosphere.

Assignment Summary For this assignment, you will make a scale model—a “core sample”—showing the layers of the Earth: crust, lithosphere, asthenosphere, mantle, outer core, and inner core. Background Information The Earth is composed of six layers with differing thicknesses and properties. The crust forms both land and seafloor. It is thickest under mountains and thinnest under ocean beds. The crust’s thickness ranges from 5 to 70 km thick. The lithosphere consists of the crust plus the upper mantle. It is solid and is about 100 km thick. The asthenosphere is a semisolid layer under the lithosphere. It is about 180 km thick. The lower mantle is 2,250 km thick and is solid, but very hot, rock. The outer core is molten rock and it is 2,266 km thick. Finally, the inner core is 1,210 km thick, and it is solid iron and nickel. Remember that as you go deeper into Earth’s layers, temperature and pressure increase. A core sample is made by drilling into the Earth and pulling out a long cylinder of rock. Geologists analyze these core samples to learn more about Earth’s history and composition. So far, geologists have not yet succeeded in drilling into Earth’s mantle. You will construct a scale model of a core sample. When something is “to scale,” it has a uniform reduction or enlargement. You will calculate how deep each layer should be in centimeters, based on the actual depth of Earth’s layers in kilometers. The percentage of the total for each layer remains the same, but the actual number of units changes.Step 5: Create a typewritten paper describing your model of Earth’s layers. a) Type several paragraphs describing your “core sample” of Earth’s layers in detail. i. Explain what a core sample is. Then, tell whether it is currently possible to take a core sample like the model you’ve created. ii. Compare and contrast the layers in your model, including the significance of the colors. iii. Discuss what it means to create a scale model. iv. Include a table with the values you determined for each layer. v. Discuss the relationships of each layer to the others, including depth. b) Answer the following question in a separate paragraph. i. How does your “core sample” model of Earth’s layers differ from the actual layers of the Earth? c) Make sure your paragraphs include correct sentence structure, punctuation, grammar, and spelling. d) Ask your teacher where you should save your work. Your teacher may also have specific guidelines about the file name you should use.

Answer:
yo I hope this gets you a good grade. I have the same thing due on Nov. 9. did it the same day it was due. good luck. you will need to make the thing yourself.
Explanation:
A core sample is a cylindrical section of a natural substance. Most core samples are made by drilling with special drills into the substance, such as sediments or rock, with a hollow steel tube, called a core drill. The hole made for the core sample is called the "core hole". It is currently not possible to take a core sample like this one.
The difference in these layers is that the farther down you go the hotter and more dense it gets. You need to make the layers different colors so you know which layer is which and, how deep the layer goes.
What it means to make a scale model is to make a model of something and make it a certain amount smaller than the original.(the entire model should be the same amount smaller than the original.)
Starting at the center, Earth has four different layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. Except for the crust, no one has ever explored these layers in person. The inner core is a solid metal ball and is extremely dense, it’s made mostly of iron and nickel.the outer core is also made from iron and nickel, just in liquid form. The mantle is Earth’s thickest layer and is made mostly of iron, magnesium and silicon, it is dense, hot and semi-solid (like caramel candy).Earth’s crust is like the shell of a hard-boiled egg. It is extremely thin and cold. The crust is made of relatively light elements, especially silica, aluminum and oxygen.
How does this “core sample” model of Earth’s layers differ from the actual layers of the Earth? Well, this model is much smaller and is Impossible to do in real life. Example, the metal used for making the hollow rods to take these core samples would melt when they get to the mantle much less the inner core.

GIIVNG BRAINLYY!!!! Universal indicator is an acid/base indicator that can be added to a solution to determine its pH. Universal indicator turns solutions different colors based on its pH. A student adds universal indicator to a solution, and the solution turns the color shown below. The solution must be what? view the attachment
Answers
Answer:
When universal indicator is added to a solution, the color change can indicate the approximate pH of the solution. Acids cause universal indicator solution to change from green toward red. Bases cause universal indicator to change from green toward purple.
Explanation:
The universal indicator turns the solution in red color then the solution must be strongly acidic. Therefore, option (B) is correct.
What is a universal indicator?A universal indicator can be described as a pH indicator made of a solution of various compounds that exhibits many smooth color changes over a wide range of pH values to indicate the acidity or basicity of the solution.
The chemical indicator is a substance that indicates the color change, or the presence/ absence of a threshold amount of a chemical species, such as an acid or base in a solution.
There are many kinds of indicators such as Universal indicator, methyl orange, litmus, phenolphthalein, and bromothymol blue. They are utilized to tell the acidity and basicity of the solution by color change.
In an acidic medium, the universal indicator will show colors such as red, orange, yellow, orangish-yellow, etc. In the basic medium, the universal indicator will change its color to blue-violet or purple. In a neutral medium, it will show green color.
Therefore, the given color is red so the solution is strongly acidic as it has a very low pH value.

Which of the following can occur after a rock is weathered?
It forms metamorphic rock.
It melts and forms igneous rock.
The sediment can form magma.
It gets compacted and forms sedimentary rock.
Answers
Answer:
It gets compacted and forms sedimentary rock.
Explanation:
After a rock is weathered, one thing that can happen is for it to get compacted and form sedimentary rock.
When a rock is weathered, sediments are produced from their erosion. These materials are collected and deposited by agents of denudation. In sedimentary basin, they get compacted, cemented and lithified. The lithified sediment will then form sedimentary rocks.A student mixes a solution of lead (II) nitrate with a solution of potassium iodide and notices the formation of a yellow solid.

The reaction of lead (II) nitrate, Pb(NO₃)₂ with KI is:
Pb(NO₃)₂(aq) + 2KI(aq) → KNO₃(aq) + PbI₂(s)
This is a typical double-replacement reaction where anions and cations exchange its couple.
All nitrates are solubles, thus, KNO₃ is not the precipitate.

. A sample of NH₃ gas occupies 57.0 liters at STP. How many molecules of NH₃ is this?
Answers
Answer:
15.30 ×10²³ molecules of ammonia
Explanation:
Given data:
Volume of ammonia = 57.0 L
Temperature = standard = 273 K
Pressure = standard = 1 atm
Number of molecules of ammonia = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
1 atm ×57.0 L = n ×0.0821 atm.L/ mol.K × 273 K
