A simulation is run exploring the random motion of particles and its role in diffusion. At the start of the program, there are 20 blue spheres on one side of the membrane and 10 red spheres on the other side. After a period of time, the distribution of spheres reaches an equal number independent of each other, so that there are 10 blue spheres and 5 red spheres on either side of the membrane. What evidence suggests that diffusion results in a dynamic equilibrium across the membrane?.
According to the facts, diffusion produces a dynamic equilibrium across the membrane, where the red and blue spheres continue to move in opposite directions.
Diffusion produces a gradient in which molecules and atoms move from one concentration to another. Essentially, it is a procedure designed to preserve equilibrium. The process continues to ensure that there is equal concentration everywhere.
For further explanation, see the image below that has been attached:
The blue spheres are more prevalent on the left side of the first diagram, while the red spheres are more prevalent on the right side.
20 blue spheres are on the left and right sides of the diagram in the question, and 10 red spheres are on the right side. Because the colored spheres are not distributed equally on the two sides of the membrane, some blue spheres will move from the left side (where there is a higher concentration) to the night side (lower concentration).
Additionally, a few red spheres will move from the left side's lower concentration to the night side's higher concentration in order to achieve an equal distribution of red and blue spheres on both sides.
Seek out the second diagram in the question where arrows indicate a change in concentration from higher to lower.
On the left, there are a total of 20 blue spheres. Therefore, 10 blue spheres from the left side of the spheres will move to the night side to achieve equal distribution.
On the right side, there are a total of 10 red spheres. Therefore, five red spheres on the right side of the board will move to the left, distributing the spheres equally.
The second image in the question provides an illustration of the aforementioned distribution.
Look for the arrows that depict the spheres moving.
The atoms and molecules are now free to move, which means they might once more result in a loss of equal concentration. In order to maintain an equal number of red and blue spheres on both sides, the red and blue spheres will therefore move continuously.
On the third diagram, look for the arrows. It demonstrates that both the right and left sides of the blue molecules or atoms are moving. Red spheres are also moving to maintain equal concentration, Similarly, this leads us to the conclusion that even when the red and blue spheres are in equilibrium, they are still moving to the ether side. Thus, despite being in equilibrium, the red and blue spheres continue to move in opposite directions.

Phenomenon: On September 26th 1991, 8 scientists locked themselves inside a smaller model of the earth's biosphere, called Biosphere 2. No one was allowed to leave or enter for two years. The scientists had to grow their own food, recycle all their human waste and water, and make sure there was the proper balance of oxygen and carbon dioxide in the air they were breathing.
This biosphere was considered a closed system because it was sealed off from the outside world. There was no exchange of liquid, solid, or gas matter. Even the bottom of the biosphere was sealed off from the earth below with a large sheet of metal. Biosphere 2 received sunlight and heat energy with the outside world, but did not exchange carbon dioxide, water, and oxygen.

Answer:
Biosphere 2 is an American Earth system science research facility located in Oracle, Arizona. Its mission is to serve as a center for research, outreach, teaching, and lifelong learning about Earth, its living systems, and its place in the universe.It is a 3.14-acre (1.27-hectare) structure originally built to be an artificial, materially closed ecological system, or vivarium. It remains the largest closed ecological system ever created.
Constructed between 1987 and 1991, Biosphere 2 was originally meant to demonstrate the viability of closed ecological systems to support and maintain human life in outer space[4] as a substitute for Earth's biosphere. It was designed to explore the web of interactions within life systems in a structure with different areas based on various biological biomes. In addition to the several biomes and living quarters for people, there was an agricultural area and work space to study the interactions between humans, farming, technology and the rest of nature as a new kind of laboratory for the study of the global ecology. Its mission was a two-year closure experiment with a crew of eight humans ("biospherians").Long-term it was seen as a precursor to gain knowledge about the use of closed biospheres in space colonization. As an experimental ecological facility it allowed the study and manipulation of a mini biospheric system without harming Earth's biosphere.
Its seven biome areas were a 1,900-square-meter (20,000 sq ft) rainforest, an 850-square-meter (9,100 sq ft) ocean with a coral reef, a 450-square-meter (4,800 sq ft) mangrove wetlands, a 1,300-square-metre (14,000 sq ft) savannah grassland, a 1,400-square-meter (15,000 sq ft) fog desert, and two anthropogenic biomes: a 2,500-square-meter agricultural system and a human habitat with living spaces, laboratories and workshops. Below ground was an extensive part of the technical infrastructure. Heating and cooling water circulated through independent piping systems and passive solar input through the glass space frame panels covering most of the facility, and electrical power was supplied into Biosphere 2 from an onsite natural gas energy center.
Biosphere 2 was only used twice for its original intended purposes as a closed-system experiment: once from 1991 to 1993, and the second time from March to September 1994. Both attempts, though heavily publicized, ran into problems including low amounts of food and oxygen, die-offs of many animals and plants included in the experiment (though this was anticipated since the project used a strategy of deliberately "species-packing" anticipating losses as the biomes developed), group dynamic tensions among the resident crew, outside politics, and a power struggle over management and direction of the project. Nevertheless, the closure experiments set world records in closed ecological systems, agricultural production, health improvements with the high nutrient and low caloric diet the crew followed, and insights into the self-organization of complex biomic systems and atmospheric dynamics. The second closure experiment achieved total food sufficiency and did not require injection of oxygen.
In June 1994, during the middle of the second experiment, the managing company, Space Biosphere Ventures, was dissolved, and the facility was left in limbo. Columbia University assumed management of the facility in 1995 and used it to run experiments until 2003. It then appeared to be in danger of being demolished to make way for housing and retail stores, but was taken over for research by the University of Arizona in 2007. The University of Arizona took full ownership of the structure in 2011.

Explanation:
How many gene pairs are involved in generating a typical 1:8:28:56:70:56:28:8:1 ratio in the f2 generation of an experimental cross? group of answer choices 6 3 4 2 5
The no. of gene pairs involved in generating the given cross in F2 generation are (4) pairs.
First we have to calculate total number of individuals that are formed in f2 generation i.e.. 1+8+28+56+70+56+28+8+1= 256
From above statement we can find out that out of 256 individuals 2 are showing the extreme/dominant characters that is the parental characters and all other individuals show recombination characters or characters different from the parental one.
If the proportion of F2 individuals displaying either of the two most extreme parental phenotypes can be calculated using the following formula, the number of genes in cases of polygenic inheritance can be estimated by the formula,
either of two extreme cases= 1/4ⁿ
=1/ 256 = 1/4ⁿ
On solving this we get n= 4
Thus 4 pairs of genes are involved in the f2 generation of an experimental cross.
A Polygenic inheritance is a phenomenon in which polygene is a gene that works in concert with other genes to slightly influence phenotypes.
Multiple alleles, such as the ABO blood group system, which is regulated by three alleles, are different from polygenic inheritance in that multiple alleles occurs when three or more alleles are present in the same locus and any two of those alleles are present in an organism.
