As porosity increases, permeability decreases It increases as particle length increases. via definition, permeability is a measure with which fluids will go with the flow though a porous rock, soil or sediment. a material that has high porosity does not have to have high permeability.
Smaller particles have a low permeability. this is due to the fact there's less space among debris, which reasons a lower porosity, which makes water travel slower through the ground. Smaller debris have a higher capillarity.
Porosity is the amount of pore area that is between particles in soil or rocks. Permeability takes this pore space and connects the voids collectively so that water can pass thru. Porosity is extra associated with garage of water, whilst permeability is extra related to groundwater motion and flow.
To calculate the permeability of a porous material, use Darcy's law equation: Multiply together the fluid discharge fee, dynamic viscosity, and distance traveled. Divide the end result from step one with the aid of the move-sectional place of the fabric elevated with the aid of the strain difference on either aspect of the material.

A. all molecular movement stops.
B. molecules move from areas of lesser concentration to areas of greater
concentration
C. sugar molecules move into a cell.
D. molecules move from areas of greater concentration to areas of lesser
concentration.
Answer:
d
Explanation:
The process of diffusion occurs when molecules move from areas of greater concentration to areas of lesser concentration. The correct option is D.
What is diffusion?The movement of essential, small molecules across the cell membrane as well as the movement of materials within cells both depend on the process of diffusion.
The exchange of gases in the lungs and gills is regulated by this process. As a byproduct of biological metabolism, carbon dioxide is released by all cells.
For example, when you pour a red color drop into the water, slowly the color molecules are evenly distributed in the whole water. It does not need any energy because it works according to the concentration gradient.
Thus, the correct option is D. molecules move from areas of greater concentration to areas of lesser concentration.

In a changing environment, which species will have the best chance for survival? Group of answer choices The ones that are super fast. The one with the largest population. The one with the biggest genetic variation. The one with the most intelligent individuals
Answer:
one with the largest poplation because they can cook,protect, and get supplies .
Explanation:
In a changing environment, the species which will have the best chances for survival are the one with the biggest genetic variation. Thus, the correct option is C.
What is Genetic variation?Genetic variation is the difference in DNA present among different individuals or the differences between the populations. The multiple sources of genetic variation include mutations and genetic recombination in species. Mutations are the ultimate source of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Variation allows some individuals within a population to adapt better to the changing environmental conditions. Because, the natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation in a population.
Therefore, the correct option is C.

1.) What could happen if you remove an organism from a food chain?
2.) What is biodiversity?
3.) Why is biodiversity important in an ecosystem?
Answer:
1. every organism on the food chain will be affected. the ones below it will have a higher population, and the ones above it will have a lower population.
2. biodiversity is the idea, that all life is different, and environments thrive with it.
3. biodiversity is important in an ecosystem because if you take out biodiversity, you essentially take out all the animals in the given ecosystem.
Explanation:
1. when you remove lets say a spider from a food chain, the bugs that it would've eaten will start growing in population from not being eaten by the spiders. the birds that wouldve eaten the spiders, will decrease from the lack of that food source.
2. is self explanatory
3. if you only had one type of bird in one ecosystem, and that was the only animal in that ecosystem, the birds would all die, because they wouldn't have anything to eat, and nothing would eat it, so they might resort to cannibalism, or, as earlier stated, they would die off, from lack of food. the ecosystem would not be sustainable.

Explain how the binomial numendature works ?
And please put an answer that makes sense
Thank you
Btw it’s science
Answer:
Binomial nomenclature is basically the scientific classification of organisms, or taxonomy, using a latin name. It uses the genus and the species. For instance, the bacteria Staphylococcus aureus uses binomial nomenclature because Staphylococcus is the genus, while aureus is the species.
Biology Dictionary states, "The genus name is also called the generic name and always begins with a capital letter. For example, binomial name for cats is Felis catus. The genus name must be unique within each kingdom (see image below) but the same genus can be used in more than one kingdom. [. . .] The species within the genus is known by other names depending on the discipline. For general usage, the species is also called the specific descriptor. In botany, it is called the specific epithet and specific name in used in zoology. A species name can be used more than once within a kingdom.The species name always begins with a lower case letter. It can be a noun or an adjective and it must agree with the Latin gender of the genus name; masculine, feminine or neuter. For example, if the gender of the genus is masculine, the species name should end in -us, -a or -um. An example of this is Passer domesticus, the house sparrow, in which Passer has a masculine gender. Endings for feminine species names include -is and -e and -or is used for neuter genders."

1)What is it about the structure of ATP that contributes to its ability to act as an energy currency?
2)When a phosphate is transferred from ATP, it can phosphorylate another molecule. How could this assist in allowing a protein to transport molecules against their concentration gradient?
Answer/Exlanation:
1) ATP (adenosine triphosphate) can be hydrolyzed such that it loses a phosphate group to form ADP (adenosine diphodphate). This is called ATP hydrolysis. This property allows ATP to act as energy currency because ATP hydrolysis releases the energy stored in the high energy phosphate bond.
2) Transporting molecules against their concentration gradient requires energy. When ATP loses its phosphate group, it can phosphorylate another molecule. This converts the molecule into its active state, giving that molecule the energy to pass through against the concentration gradient.
1) The ability of the ATP compound structure to act as an energy currency has been explained in the answers.
2) The method used by ATP to allow protein transport molecules against their concentration gradient has been explained below.
1) ATP is an acronym that stands for Adenosine triphosphate. This compound called ATP is divided into three phosphate groups with phosphate bonds that possess very high energy. Now, when water is added to ATP, the phosphate bonds that possess high energy will be broken down thereby releasing energy and producing adenosine diphosphate (ADP).
2) We saw above that when ATP undergoes hydrolysis, the phosphate bonds are broken down to form ADP and releases energy. However, it can undergo further phosphorylation to form another molecule which becomes energized when it goes to a higher energy state.
Now, In this higher energy state it gets to, it will be observed that the protein will possess enough energy to transfer molecules against a concentration gradient that requires energy.
