The concentration inside the cell is greater than outside describes a cell after diffusion. Therefore, the correct option is option A among all the given options.
What is diffusion?Diffusion is regarded a passive mode of cellular transport in biology since it does not require additional energy to occur. It is the primary mode of transport for vital chemicals (such as amino acids) between cells. It is necessary for the production of energy via respiration and photosynthesis.
Some chemicals, referred to as "simple diffusion," are not controlled by the cell's own proteins. membrane. It is found in substances with low molecular weight, such as water, gasses and fat-soluble compounds. The concentration inside the cell is greater than outside describes a cell after diffusion.
Therefore, the correct option is option A.

What type of elements make up ionic bonds?
Ionic bonds are formed between ionic compounds, Ionic compounds are formed when metals join with nonmetals.
What are ionic bonds?Ionic bonds are electrostatic bonds that are formed between metals and nonmetals. It is an electrostatic attraction between oppositely charged ions in a chemical compound.
These bonds are formed when two or more atoms lose or gain electrons. An example of ionic bonds can be seen in the NaCl compound.
Na⁺ + Cl⁻ = Na⁺Cl⁻
NaCl is formed by the joining of oppositely charged elements. They constitute salt. Salt is made up of ionic compounds, so it easily dissociates into sodium and chloride when mixed in water.
Thus, ionic compounds are created when metals combine with nonmetals, and these combinations result in the formation of ionic bonds.

How could energy have played a role in the different rock types forming?
Answer:
Energy from different sources leads to different types of rocks.
Explanation: Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into different types of rock.
Rocks are formed in earth by the deposition of minerals and decomposition of massive tectonic plates by the hot magma which is melted by the heat energy radiated from sun.
What are different types of rocks?There are broadly three different types of rocks, namely sedimentary rocks, igneous rocks and metamorphic rocks . They are classified based on their formation and composition.
The magma that the molten mineral fluid inside the earth crest melts under heat radiated from sun and this hotter fluid flows results in movement of tectonic plates and decomposition at some places.
Therefore, the heat energy and resultant convection current leads the tectonic plate boundaries and formation of different kinds of rocks which are stimulated by the action of air and water.

A helium balloon has a volume of 2.00L at 101kpa. As the balloon rises the pressure drops to 97.0kPa. What is the new volume?
Answer:
2.08L
Explanation:
V1 = 2.00L
P1 = 101kPa
P2 = 97.0kPa
V2 = ?
from Boyle's law,
P1V1 = P2V2
101 × 2 = 97 × V2
V2 = 202/97 = 2.08L
Therefore, the new volume is 2.08L
Answer:
2.1L
Explanation:
Given parameters:
Initial volume = 2L
Initial pressure = 101kPa
Final pressure = 97kPa
Unknown:
Final or new volume = ?
Solution:
Now to solve his problem which relates pressure and volume, we simply apply Boyle's law which is mathematically expressed below;
P₁ V₁ = P₂ V₂
P and V are pressure and volume
1 and 2 are initial and final states;[tex]\frac{101 x 2}{97}[/tex]
101 x 2 = 97 x V₂
V₂ = [tex]\frac{101 x 2}{97}[/tex]
V₂ = 2.1L

Explanation:
calculate the chemical amount of ammonia present in a 11.22g sample of the compound
Answer:
3.97 x 10²³atoms
Explanation:
Given parameters:
Mass of ammonia = 11.22g
Unknown:
Chemical amount of ammonia present = ?
Solution:
The chemical amount present in a substance is the number of atoms it contains.
To solve this problem, from the given mass find the number of moles first.
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of NH₃ = 14 + 3(1) = 17g/mol
Number of moles = [tex]\frac{11.22}{17}[/tex] = 0.66mole
1 mole of any substance contains 6.02 x 10²³ atoms
0.66 mole of ammonia will contain 0.66 x 6.02 x 10²³ atoms
= 3.97 x 10²³atoms

Fruit fly cells have 8 chromosomes. After mitosis, you would expect a resulting fruit fly daughter cell to have how many chromosomes? Explain your answer.
After mitosis, it is expected that the daughter cells of a fruit fly with 8 chromosomes should have 8 chromosomes.
MITOSIS:
Mitosis is the kind of cell division in which a single cell produces two daughter cells that are genetically identical to the parent cell. Mitosis results in daughter cells that possess the same number of chromosomes as the parent cell, hence, it is called duplication division. This means that mitotic division maintains the chromosome number of parents in the daughter cells. For example, a fruit fly with 8 chromosomes will produce daughter cells with 8 chromosomes each. Therefore, after mitosis, it is expected that the daughter cells of a fruit fly with 8 chromosomes should have 8 chromosomes.Learn more at: https://brainly.com/question/3327479?referrer=searchResults

If the wavelength of light will cause electrons to be removed from the metal (creating the photoelectric effect). What is the effect of doubling the photon flux of light?
Answer:
The number of photoelectrons are increased
Explanation:
According to Albert Einstein, when light falls on a clean metal surface, electrons are ejected from the clean metal surface. This is known as photo electric effect.
The kinetic energy of the emitted photoelectron depends on the energy of the incident photon and the work function of the metal. If the energy of the incident photon is less than the work function of the metal, photoelectric effect does not occur.
Below a given threshold frequency or wavelength called the threshold frequency or threshold wavelength photoelectric effect does not occur.
However, doubling the photon flux of light doubles the intensity of the light. This only leads to increase in the number of photons and have nothing to do with the energy of the emitted photoelectrons.
