soil, rock, organic layer
Explanation:
Permeability is the ability of a layer of rock to transmit fluid such as oil or water
The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter
Rocks such as gravels, and sparingly cemented sands have high permeability
The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water
Therefore, water moves easily between layers soil, rock, organic layer

Which is not a unique property of water
Answer:
A
Explanation:
All of the other options are specific to water, but quite a few liquids cool off a lot faster than water.
water cools very rapidly is not a unique property of water. Thus option A is correct.
what are the properties of water molecule ?It has no taste, odor, or transparency, where the nucleus of the oxygen atom attracts electrons strongly than the nuclei of the hydrogen atoms.
In water molecule oxygen is more electro negative and electron-greedy than hydrogen, results in the development of a partial negative charge on the oxygen of the water and a partial positive charge on the hydrogen end.
Water shows strong cohesive property where the attraction of molecules for other molecules of the same kind is referred to as cohesion.
Surface tension is defined as the tendency of the surface to resist rupture when they are subjected to stress due to cohesive forces.

A cell has chloroplasts, numerous ribosomes, an endoplasmic reticulum, and a cell wall. What type of cell is this?
Answer:
The cell with chloroplasts, abundant ribosomes, plus an endoplasmic reticulum, and a cell wall is of the plant cell type.
Explanation:
Plant cells are eukaryotic cells found in all plants, with specific characteristics given their ability to be autotrophic and use solar energy to synthesize their nutrients. The presence of many ribosomes and a developed endoplasmic reticulum is due to their high capacity for plant protein synthesis.
One characteristic that differentiates plant and animal cells is the presence of a cell wall, which surrounds the cell membrane, and chloroplasts. Chloroplasts are responsible for making the process of photosynthesis possible.

PLEASE HELP ME WITH THIS AND HURRY WILL MARK AS BRANLIEST!!!!!! Why do leaves change color in the fall? Research this phenomenon and write a two-page report describing what happens. Be sure to include an introduction and a conclusion to your report. Use the information you have learned in this lesson about chlorophyll, the green plant pigment, and its role in photosynthesis to help you explain what happens in the fall.
Answer:
Leaves are always the color they turn in the fall
Explanation:
The chlorophyll created when the leaves use sunlight to create energy for the tree has a green pigment that covers the leaves actual colors. As the leaves separate from the trees they stop making chlorophyll, thus allowing the leaves true colors to return.
I hope this helps and good luck on that two-pager!
Answer:
During the fall the day gets shorter hence less sunlight this results to leaves stopping their food making process. The chlorophyll breaks down, the green color disappears and the yellow to orange color becomes visible

If a woman is heterozygous for widow's peak
(widow's peak is dominant over a smooth hairline) has children with a man with a smooth hairline, what
are the possible phenotypes of their children?
It is impossible to determine the possible phenotypes.
O All of their children will have a widow's peak.
O None of their children will have a widow's peak.
It is possible for their children to either have widow's peak or a smooth hairline.
Answer:
It is possible for their children to either have widow's peak or a smooth hairline.
Explanation:
Let's say that the widow's peak allele is W (dominant) and the smooth hairline is w (recessive).
A woman heterozygous for widow's peak is Ww. A man with a smooth hairline must have two copies of the smooth allele since it is a recessive trait, so he must be ww.
The cross is Ww x ww
W w
w Ww ww
w Ww ww
There is a 50% chance that the children will have the genotype Ww, and therefore have a widow's peak. There is a 50% chance the children will be ww, and will therefore have a smooth hairline.
So, It is possible for their children to either have widow's peak or a smooth hairline.

Why do planets close to the sun have thin atmospheres and the planets far away from the sun have thick atmospheres. Use what you know about the nebular theory.
Answer:
There are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres. The reason why the outer planets are larger is probably down to two major factors. The first is simply the amount of material available which may be accreted to a planet. Clearly, the further away from the Sun, the longer the orbit (twice as far means an orbit twice the physical length).

if a sample contains 20g of an isotope that has a half life of 1000 years how much will be left after 2000 years
After 2000 years, there will be 5g of the isotope remaining.
What is an isotope?If an isotope has a half-life of 1000 years, it means that after 1000 years, half of the original sample will have decayed. After another 1000 years (2000 years total), half of the remaining sample will have decayed, and so on.
To calculate how much of the sample will be left after 2000 years, we can use the following formula:
[tex]N = N_{0} * (1/2)^ (t/T)[/tex]
where:
N = the amount of the isotope remaining after time t
N0 = the initial amount of the isotope
t = the time that has elapsed
T = the half-life of the isotope
Plugging in the values from the problem, we get:
N = 20g * (1/2)^(2000/1000)
N = 20g * (1/2)^2
N = 20g * 1/4
N = 5g
Therefore, after 2000 years, there will be 5g of the isotope remaining.

The plasma membrane is selectively permeable. It allows some substances to enter and leave the cell unrestricted while others are restricted. Some toxins produced by certain bacteria cross the plasma membrane, interfering with normal chemical reactions, and ultimately killing the affected cell. Why are cells unable to stop the flood of these harmful substances into the cell
Answer:
There are specific receptors present on the surface of the normal cell membrane to recognize the molecules to allow them to pass or not. Most of the bacterial toxin are water-soluble molecules, and bound to the cell surface and interact with them as some time antibody-antigen interaction or cell recognition does not occur that form a pore in the cell membrane and toxins move into the cell.
Once toxins enter the cell they attack intracellular targets through endocytic vesicles. Ultimately these ends in cell death.
The cells are not able to stop the flow of the mentioned harmful substances into the cell as they fail to recognize them as foreign entities. These foreign toxins have intracellular targets with which they bind and lead to death of the cell.
Cell death due to foreign toxins:The plasma membrane is formed of lipids. The toxins produced by the bacterial cells are water soluble. Therefore, they identify particular receptors on the membrane and associate with them. Thus, cell at certain occasions fail to identify them as foreign entities.
They combine with the plasma membrane of the cell and induce pore formation, however, there are many toxins that invade the cell and possess intracellular targets via endocytic vesicles. With the help of these vesicles, they deliver their enzymatic domain into the cytosol and results in the death of the cell by obstructing the metabolism of the cell.
Thus, cells fail to identify the bacterial toxins as foreign entities and they invade the cell and results in cell death.

Humans deplete the most resources when
Answer:
Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources (see also mineral resource classification). Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource, the more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, the most known being: Aquifer depletion, deforestation, mining for fossil fuels and minerals, pollution or contamination of resources, slash-and-burn agricultural practices, Soil erosion, and overconsumption, excessive or unnecessary use of resources.
Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and consumption of fossil fuels. Depletion of wildlife populations is called defaunation.
