Why does humus tend to increase with the clay content of soil?
A.
As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which decreases the rate of decomposition.
B.
As the clay content increases, the amount of plant lignin in the soil increases.
C.
As the clay content increases, the permeability decreases, which increases the rate of decomposition.
D.
As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which increases the rate of decomposition.
Answer:
A.
As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which decreases the rate of decomposition.
Explanation:
This is true because, humus which is the dark rich matter made up of organic matter would be able to be adsorb into the clay content of the soil due to the size of the particles component. The surface area in the soil is a strong factor when compared with other soil type with smaller surface area.

The size of a frog population in a pond remains fairly constant over a period of several years because of a. decreasing competition b. environmental carrying capacity c. excessive dissolved oxygen d. the depth of the water
Answer:
d
Explanation:
Equipment required: One or more buckets of water (or access to a garden hose connected to a water supply).
Pour one or two buckets of water (or run water from a garden hose) on bare ground (grass or soil is OK). Observe how the water moves. Some of the water may soak into the ground and some may flow over it. Pour a few more buckets (or run more water from the garden hose) over the same area and observe any differences in the behavior of the water. Does it still soak into the ground? Discuss how the moisture conditions in the soil will affect how much water gets absorbed. Would water be more likely to run off after the ground has been saturated by a heavy rainstorm? Discuss what happens to the water that gets absorbed into the ground.
Repeat the demonstration on a paved surface such as a driveway or sidewalk and document the differences. With no soil to absorb this water, what would happen in a heavy rainstorm? How would an engineer in charge of a city’s flood control system prepare for the runoff generated on paved parking lots and roads in a heavy rainstorm?
Answer:
No water will be soaked by the soil if it has saturated condition.
Explanation:
If the soil does not reached to its saturated point so the soil will soak the water while on the other hand, if the soil reached to its saturated point so it will not absorb the water. If soil has more water so it will not be able to absorb more water. Yes, water will be more likely to run off after the ground has been saturated by a heavy rainstorm and the water absorbed by the soil remain in the soil for the plant while the large quantity of water percolates down and reach the water table. With no soil to absorb water, the water goes to rivers and streams when a heavy rainstorm held. The engineer has to built a well drainage system in order to remove runoff water from the roads and pavement and avoid flood condition.

Energy Storage in Humans Free glucose in blood has 4 kilocalories per gram, 40 kilocalories of energy storage, and a few minutes of life support time. Glycogen has 4 kilocalories per gram, 600 to 1600 kilocalories of energy storage, and 1 day of life support time. Lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time. What is the best conclusion based on this data? Blood is a primary location for energy storage. Fat molecules contain more energy-containing bonds than simple sugars. A gram of glycogen has twice as much energy as a gram of fat. The human body stores approximately 1,000 kcal of glucose.
Answer:
Fat molecules contain more energy-containing bonds than simple sugars.
Explanation:
Lipids are a large group of mostly non-polar hydrophobic hydrocarbons. They include fats and oils, waxes, phospholipids and steroids. They serve many functions in living organisms such as energy storage molecules, information molecules, insulation against cold in some animals etc.
From the information provided above, lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time. When energy provided per gram by lipids is compared with that of either glucose or glycogen, lipids provide more than twice the energy of that of glucose or glycogen. Similarly, the energy storage capacity of lipids over 1000 times that of glucose and 50 times that of glycogen. Therefore, fat molecules (an example of lipids) contain more energy-containing bonds than simple sugars (e.g. glucose)

What is the function of ATP, and why is it important?
ATP(adenosine tri-phosphate) stores energy between it's 2nd and 3rd phosphate groups. When the 3rd phosphate group is released ADP(adenosine mono-phosphate) is created and energy is being released. This molecule is important because it stores the energy from cellular respiration and most cellular processes require the energy released by ATP.

Your lab group is experimenting with the diffusion of molecules across a membrane. Dialysis tubing is used as a model cell
membrane, because is it semi-permeable, allowing small molecules to cross the membrane, but NOT larger molecules, like starch
A starch solution is placed in the dialysis tubing and then the dialysis tubing is placed in an iodine and water solution. lodine is
used as an indicator for the presence of starch. Normally, iodine is a yellow-brown color, but in the presence of starch, it turns a
deep purple. After observing the experimental setup for 20 minutes, the iodine solution remains brown, but the starch solution
inside the dialysis tubing is purple and swollen. Based on what you learned from the lab, starch is MOST likely to cross the cell
membrane at which of the points indicated on the diagram?
ah
ing
Starch requires ATP energy for transport and therefore cannot cross the dialysis tubing into the iodine solution.
Cellular respiration is a series of complicated reactions. Some of the enzymes that are necessary for the reactions to take place effectively are not produced by the body and must be eaten in a person's diet. Which answer correctly explains what happens when a person's diet lacks the necessary enzymes for cellular respiration?
Answer:
Lack of necessary enzymes for cellular respiration will lead to a decrease in the cell's energy level will diminish as the enzyme decreases.
Explanation:
Cellular respiration is a bunch of metabolic responses and cycles that occur in the cells of life forms to change over compound energy from oxygen atoms or supplements into adenosine triphosphate (ATP), and afterward discharge side-effects.
The responses engaged with breath are catabolic responses, which break enormous particles into more modest ones, delivering energy in light of the fact that frail high-energy bonds, specifically in sub-atomic oxygen, are supplanted by more grounded bonds in the items.
Respiration is one of the key ways a cell discharges substance energy to fuel cell movement. The general response happens in a progression of biochemical advances, some of which are redox responses. Albeit cell breath is in fact a burning response, it unmistakably doesn't take after one when it happens in a living cell in view of the moderate, controlled arrival of energy from the arrangement of responses.
Answer:
D. The cell's energy level will diminish as the enzyme decreases

Plants play a crucial role in the carbon cycle because they do not release carbon dioxide during cellular respiration allow carbon to enter an ecosystem via photosynthesis have special bacteria that live in their root systems are chemically converted into fossil fuels when burned
Answer:
Allow carbon to enter an ecosystem through photosynthesis
Explanation:
Though plants are known to sustain life through the process of photosynthesis. In this process plants simply takes in carbon dioxide and releases oxygen.
However, this is a type of process is considered to be active during the day, while at night plants absorb oxygen and release carbon dioxide
Hence, Plants play a crucial role in the carbon cycle because they "Allow carbon to enter an ecosystem through photosynthesis."
Explains how the atoms that make up glucose can be used to construct macromolecules
Answer:
In the dehydration synthesis reaction (attached) , two molecules of the sugar glucose (monomers) combine to form a single molecule of the sugar maltose (macromolecule)
Explanation:
Macromolecules are formed from glucose by condensation polymerization.
Macromolecules are formed by the agglomeration of small molecules called monomers. These monomers are simple molecules that can be joined together to form a larger molecule.
Glucose can serve as a monomer that is joined together to yield macromolecules such as polysaccharides. These larger molecules are formed by the process of condensation polymerization in which a water molecule is lost.

Answer:
There are 60 grams of the salt in 12 teaspoon of it
Explanation:
We can rephrase the question by saying, if 1 teaspoon has 5.00 grams of salt, how many grams does 12 teaspoon have? We can then equate the answer by doing the following
1 teaspoon = 5 grams
12 teaspoon = ?
Cross-multiply
? = 12 × 5/1
? = 60 grams
There are 60 grams of the salt in 12 teaspoon of it
