The Chalfont soils are a distinct group of soils found in Pennsylvania, New Jersey, and Maryland. The parent material for these

soils is made of silt-sized particles. These particles were originally deposited by glaciers and then later eroded and redeposited in their current location by the wind.
Which of the following terms best describes the Chalfont soils' parent material?
A.
topsoil
B.
humus
C.
loam
D.
loess

Answer:

D. loess

Explanation:

Loess is a type of fertile soil formed from the action of winds that allows the accumulation of fine and very small grains (between 20 and 50 micrometres) of clay, calcium, feldspar, quartz and other minerals. This type of soil is found mainly in regions of humid or humid climate, with mild relief and significant presence of winds. About 10% of the soil on planet Earth is Loess type or similar, however, this type of soil is found in Pennsylvania, New Jersey, and Maryland.

I believe the answer is D. loess. The loess soil is a predominantly silt-sized sediment formed by accumulation of wind blown dust. This soil is highly porous, homogeneous, pale yellow and friable. One way of forming loess is from glaciers and that is why they contain glacially ground flour like clay and silt.

Which atoms exist as diatomic molecules?
Nikitich [7]
If the diatomic molecule consists of atoms from two different elements, then it is aheteronuclear diatomic molecule. There are seven elements that naturally occur as homonucleardiatomic molecules in their gaseous states: hydrogen,nitrogen, oxygen, fluorine,chlorine, bromine, and iodine

The following combinations are not allowed. If n and ml are correct, change the l value to create an allowable combination:
motikmotik

The allowable combination for the atomic orbital is n=3, l=1, m_{l}=-1.

<h3>What are the three quantum numbers of an atomic orbital?</h3>

Three quantum numbers specify an atomic orbital:

- The principal quantum number, n, which is a positive integer, describes the relative size of the orbital and its distance from the nucleus.

- l is the angular momentum quantum number that is related to the shape of the orbital; l is an integer from 0 to n-1 (so n limits l ),

- $\boldsymbol{m}_{l}$ is the magnetic quantum number that prescribes the three-dimensional shape of the orbital around the nucleus; m_{l} values are integers from -l to =l(l limits ml)

For n = 3, l can have three values: 0, 1, and 2. Since m_{l} values are integers from -l to 0 to +l, for l = 0 the value of m_{l} cannot be -1 (l = 0 has m_{l}= 0).

There are two l values that are consistent with n and m_{l} values:

l=1 or 2

Therefore, the allowable condition is n=3, l=1, m_{l}=-1.

In the early twentieth century, what was Alexander Fleming’s hypothesis concerning the relationship between a yellow-green mold
SpyIntel [72]

Answer:

The correct answer is the option c)He thought the mold had released a chemical that prevented the bacteria’s growth.

Explanation:

In the 1920s, Alexander Fleming was working in his laboratory at St. Mary's Hospital in London when, almost by accident, he discovered a naturally growing substance that could attack certain bacteria. In one of his experiments, Fleming observed that colonies of a bacterium had been depleted or removed by a mold that grew on the same Petri dish. He observed that the bacteria furthest from the fungus had grown to produce large-sized colonies, while the colonies closest to the fungus were tiny. He determined that mold made a substance that could dissolve bacteria. The fungus was penicilium chrysogenum and thus Fleming called this substance penicillin, by the name of the mold that produces it. Thus, after several years of experiments in 1930, Howard Florey and Ernest Chain developed at Oxford University the procedures to produce pure penicillin from the fungus that Fleming isolated. Thus penicillin could be concentrated by Florey and Chain, and in 1945 they shared with Fleming the Nobel Prize in Medicine.

Then, <u><em>the correct answer is the option c)He thought the mold had released a chemical that prevented the bacteria’s growth.</em></u>
