What is Meiosis?

Meiosis may be defined as a type of cell division where a parental cell produces four daughter cells. It is also known as Reductional division.

During the egg formation in meiosis, the diploid cell undergoes cell division and a haploid cell will be formed.

During the process of meiosis, both pairs of homologous chromosomes are paired with each other to form the genotypes. It excluded the phenomenon of crossing over.

Therefore, it is well described above.

If potassium permanganate was placed in a solution of boiling water (100°C), would the rate of diffusion be greater than diffusion in cold water? Would diffusion of potassium permanganate in boiling water be greater than diffusion in warm water?

Answers

The rate of diffusion increases as temperature increases.Hence, the rate of diffusion will be the greatest in boiling water then warm water and cold water at last

The movement of molecules along a concentration gradient is known as diffusion. It is a significant process that all living things go through. Diffusion facilitates the flow of materials into and out of cells. Increased energy from higher temperatures causes the molecules to move more quickly, speeding up the diffusion process. Lower temperatures cause the molecules' energy to drop, which lowers the diffusion rate. The rate of diffusion increases with increasing concentration differences. The particles will move and mix more quickly at a greater temperature because they will have more kinetic energy.

Hence, the diffusion rate will be boiling water>warm water>cold water

oxygen will diffuse into cell in the diagram
why?

Answers

Answer: Because there's a higher concentration of oxygen molecules outside the cell compared to the cell's cytoplasm, you'll see that oxygen diffuses into the cell along this concentration gradient.

Explanation: Your welcome!!!

Oxygen will eventually diffuse into the cell because there is a higher concentration of oxygen molecules present outside the cell with respect to the cytoplasm of the cell.

What is Diffusion?

Diffusion may be defined as a type of process through which the movement of individual molecules of a substance takes place from an area of higher concentration to an area of lower concentration through a semipermeable barrier.

According to the definition of diffusion, the concentration of molecules of oxygen is found to be higher in the outside of the cell as compared to the cytoplasm. So, the molecules of oxygen start the process of diffusion in order to increase the concentration of oxygen in the inner atmosphere of the cell.

Therefore, oxygen will eventually diffuse into the cell because there is a higher concentration of oxygen molecules present outside the cell with respect to the cytoplasm of the cell.

∙ Transcription is the process of RNA production from DNA.

∙ During transcription, RNA polymerase produces a copy of a gene from the DNA to mRNA.

∙ During transcription, the DNA location at which RNA polymerase interacts is termed a promoter.

∙ Transcription begins with attachment of sigma factor proteins to the RNA polymerase holoenzyme, therefore, allowing it to bind to promoter DNA.

∙ RNA polymerase forms a transcription bubble, which divides the two strands of the DNA helix.

∙ Then RNA polymerase proceeds towards the transcription start site for the process of transcription.
