Sara poured some sand into a pan. How could Sara best demonstrate wind
erosion using this model?
A. Use a spray bottle to moisten the sand with water.
B. Blow into a drinking straw over the sand.
C. Pour a glass of water into the sand.
D. Let a block of ice melt over the sand.
Answer:
b
Explanation:
reason why is because blowing through a straw demonstrates air so when you blow it against sand or dirt it blows pieces of soil or sand away and in different areas.
Blow into a drinking straw over the sand which demonstrate wind erosion using this model. So, the correct option is (B).
What is Wind erosion?Wind erosion is defined as the natural process that moves soil from one place to another by wind energy which can cause significant economic and environmental damage.
It is a major cause of land degradation in arid and semi-arid grasslands, which is one of the processes leading to desertification. Significant wind erosion occurs when strong winds blow on light textured soils that have been heavily grazed during periods of drought.
It can happen anytime and anywhere when the wind blows which can happen in any area where sand or soil is not compacted or is of fine grained nature. Wind erosion not only destroys the land by drying out the soil and depleting the land's nutrients but also results in air pollution.
Thus, blowing into a drinking straw over the sand which demonstrate wind erosion using this model. So, the correct option is (B).

Answer:
here's your answer
Explanation:
When buried six feet down, without a coffin, in ordinary soil, an unembalmed adult normally takes eight to twelve years to decompose to a skeleton. However if placed in a coffin the body can take many years longer, depending on type of wood used. For example a solid oak coffin will hughly slow down the process.

What are the two units of measure
Answer:
hope this helped:)
Explanation:
Systems of Measurement: there are two main systems of measurement in the world: the Metric (or decimal) system and the US standard system. In each system, there are different units for measuring things like volume and mass.
There are many different units of measurement that apply to different quantities and variables. However, if we are talking about the most basic units of measurement of the International System of Units (SI), they are:
1. The unit of measurement of length or distance is meter (m). It is often used to measure the size or dimensions of an object.
2. The unit of measurement of mass is the kilogram (kg). It is used to determine how much material is present in an object.
Other derived units of the SI system, such as the second for time, the liter for volume, and the newton for force, are all derived from these two basic units: the meter and the kilogram.

Exceeding threshold depolarization at the trigger zone______the likelihood of generation of an action potential.
Answer: Exceeding threshold depolarization at the trigger zone decreases the likelihood of generation of an action potential.
Explanation:
Exceeding threshold depolarization at the trigger zone decreases the likelihood of the generation of an action potential.
What is threshold depolarization?Excessive depolarization at the trigger zone reduces the likelihood of an action potential being generated. The amplitude of the action potential decreases with distance. The number of action potentials increases as the frequency of stimulation to the trigger zone increases.
Because the potassium channels within the cell membrane are delayed, any additional sodium entry activates an increasing number of voltage-gated sodium channels. Depolarization above the threshold causes an increase in Na conductance sufficient for inward sodium movement to instantly swamp outward potassium movement.
Therefore, Excessive depolarization at the trigger zone reduces the likelihood of an action potential being generated.

The inner and outer surfaces of a cell membrane carry a negative and positive charge, respectively. Because of these charges, a potential difference of about 70 mV exists across the membrane. The thickness of the membrane is 8 nm. A) If the membrane were empty (filled with air), what would be the magnitude of the electric field inside the membrane? (Assume that this field would be constant in magnitude). B) If the dielectric constant of the membrane is K = 3, what would the field be inside the membrane?3) Cells can carry ions across a membrane against the field ("uphill") using a variety of active transport mechanisms. One mechanism does so by using up some of the cell's stored energy (converting ATP to ADP, for those who remember their biochemistry). How much work does it take to carry one sodium ion (charge = +e) across the membrane against the field?
The inner and outer surfaces of a cell membrane carry a negative and a positive charge, respectively. Because of these charges, a potential difference of about 0.070 V exists across the membrane. The thickness of the cell membrane is 8.0 x 10-9 m.

Indicate which of the following observations can be made when observing growth on nutrient agar. Group of answer choices Gram reaction of growth Acid-fast morphology Amount of growth Opacity/clarity of colonies Color of colonies Presence or absence of endospores Shape and /or pattern of growth
Answer:
Amount of growth
Opacity/clarity of colonies
Color of colonies
Shape and /or pattern of growth
Explanation:
An agar plate is a Petri dish containing agar as a solid growth medium supplied with nutrients (i.e., an enriched medium), which enable to culture different microbes ranging from fungi to bacteria. Colony morphology is a widely used approach to describe the unique features of bacteria colonies growing on agar media. These colony features include, among others, shape (round, circular, punctiform, irregular), elevations/depressions (convex, concave, flat), textures (dry, moist, crusty, dull, shiny, mucoid, friable, rough), colors (cream, white, purple, gray, red, green, yellow, blue), etc.
The observation that could be made regarding the growth over nutrient agar would be:
C). Amount of growth
D). Opacity/clarity of colonies
E). Color of colonies
G). Shape and/or pattern of growth.
Observation
The growth of nutrient agar can be observed in above-mentioned ways. The area covered during the growth, the level of clarity amongst them, the color developed by them, and their size and formation as well.This assists in making worthy deductions about them.Thus, options C, D, E, and G are the correct answers.Learn more about "Morphology" here:

How can no color change in the broth and a conversion to a yellow color both be considered negative results?
Answer:
Explanation:
A Pure bacterial culture must be grown in sterile tryptophan or peptone broth for 24–48 hours before performing the test. A sterile environment helps to avoid contamination.
When a test is conducted and it shows the presence of a red or red-violet color in the surface alcohol layer it means the result is positive
But when the colour is yellow it indicate negative reaction due to glucose fermentation.
A deviation from two color may also occur when we have an orange color. This colour change is due to the presence of methyl indole
When there is no color change this indicate No decarboxylase which is an enzyme needed for the fermentation reaction.
Color changes are indicator of how successful the reaction was.
