molecules move in and out of a cell by diffusion. the picture shows a cell molecules both inside and outside the cell how will the molecules in this illustration move as a result of diffusion
out of the cell
into another cell
to the extern environment
into the cell
Answers
Answer: The molecules on the exterior of the cell will move inwards due to the difference in concentration
Explanation:
This happens because of Endosmosis, where the water molecules move from a region of higher concentration to a region of lower concentration through a semi-permeable membrane. Endosmosis is when the cell swells up due to a higher concentration in the exterior of the cell and a lower concentration in the interior of the cell.
Therefore, the water molecules move inside the cell until the concentrations of the exterior and the interior of the cell is balanced
Going by the diagrammatic illustration, the molecules would move into the cell until an equilibrium is reached.
Diffusion generally involves the movement of molecules from the region of higher concentration of a molecule to the region of lower concentration of the same molecule. The net movement will continue until both sides have equal concentrations of the molecule.
Looking at the diagram, there are more of the molecule outside the cell than inside of it. Thus, the molecules will keep moving inside the cell until both the outside and inside have the same concentration.

A student performs an experiment to study the transport of water in and out of cells. He uses clear, semi-permeable plastic bags to represent the cell membrane. The student places three plastic bags of the same size, each containing a 1% concentration sucrose solution, into three different beakers. One beaker contains distilled water, another beaker contains a 3% concentration sucrose solution, and the third beaker contains a 1% concentratIon sucrose solution. The diagram shows the students experimental setup, the plastic bag before it is placed in the beakers, and the appearance of the bags after an hour in each solution. Which statement provides a conclusion about the transport of water in and out of cells based on the results of the students experiment?
Answers
Answer:
B
Explanation:
A. Water moves freely both inside and outside the cell independent of the solute concentration.
B. Water movement into the cell is dependent on the percent concentration of solutes both inside and outside the cell.
C. Water transports solutes out of the cell to balance the percent concentration of solutes both inside and outside the cell.
D. Water moves into the cell solutes move out of the cell to ensure their concentration is balanced both inside and outside the cell.
The correct statement that provides a conclusion about the transport of water in and out of the cells is that water movement into the cell is dependent on the percent concentration of solutes both inside and outside the cell.
Water molecules will always move from the region of higher water potential to the region of lower water potential. The more the solute concentration of a solution, the lower the water potential compared to a solution with a lower solute concentration.
Hence, water will move from the beaker containing distilled water into the plastic bag containing a 1% sucrose solution until an equilibrium is established - the solution in the beaker is hypotonic to the one in the bag.
On the contrary, water will move from the bag containing 1% sucrose solution into the beaker containing 3% sucrose solution until there is no longer any net movement of water - the solution in the beaker is hypertonic to the one in the bag.
There will not be any movement of water from the bag to the beaker containing 1% sucrose because both solutions are of the same concentration, that is, isotonic.

The length of the cell when the number is fully written is twenty millionth meters long.
Given that the length of the cell is 2 x 10⁻⁵ meters long.
1 millionth = 0.000001 = 10⁻⁶
The length of the cell = 2 x 10⁻⁵ meters = 20 * 10⁻⁶ meters
Therefore the length of the cell when the number is fully written is twenty millionth meters long.

Answers
Answer:
1. 6.7%
hope it helps <3
The percentage deviation in the student's calculation is 6.74%.
We have a student who incorrectly measured the volume of a mineral sample.
We have to determine student's approximate percent deviation.
How to calculate the Percentage deviation ?In order to calculate percent deviation , subtract the true value from the measured value, then divide by the true value, then multiply by 100.
According to the question -
Measured volume (M) = 83 cubic centimeters.
Actual Volume (A) = 89 cubic centimeters.
ΔV or [tex]$\delta[/tex]V = M - A = 83 - 89 = - 6
Therefore -
|Percentage deviation| = [tex]\frac{\delta V}{A} \times 100[/tex] = - ( [tex]\frac{6}{89} \times 100[/tex]) = - 6.74 % = 6.74%
Hence, the percentage deviation in the student's calculation is 6.74%.

how come human populations differ from other animal populations
Answers
Answer:
Animal species come in many shapes and sizes, as do the individuals and populations that make up each species. To us, humans might seem to show particularly high levels of morphological variation, but perhaps this perception is simply based on enhanced recognition of individual conspecifics relative to individual heterospecifics. We here more objectively ask how humans compare to other animals ...
Explanation:
With in population, humans show low levels body height variation in comparison to variation observed in other animal population.
Similarly, human population does not show distinctive levels of body mass variation.
What are the importance of studying human population?The study of population helps us to understand the process that influence the size, growth, characteristics, and distribution.
Population studies highlight these problems for society, administrators, political System, economic Planning

The most likely result of turning off p53 is cells undergo uncontrolled division. Hence option B is correct.
What are genes?Genes are defined as the fundamental genetic component transferred from parent to child. Genes are composed of DNA sequences and are organized sequentially at specified sites on chromosomes in the cell nucleus. The foundation of the body is made up of cells. Your body is made up of billions of interconnected cells in every part. Chromosomes are the units on which genes are organized.
Diseases like cancer can result from an alteration in the cell cycle's regular regulation. When the cell cycle is out of balance, cells have the potential to randomly divide and accumulate genetic errors that can cause a malignant tumor.
Thus, the most likely result of turning off p53 is cells undergo uncontrolled division. Hence option B is correct.
