Answer:
The correct answer would be - the cell will get water and expand.
Explanation:
If a cell with a higher salt concentration is placed ins a low salt concentration solution then the water will move through the cell membrane into the cell and the cell will swell or expand.
Water always moves from a low solute concentration to a high concentration area, therefore, if the cell has more salt concentration than outside the cell water move inside the cell which leads to an increase in the water concentration inside the cell and expands its size.
Answer: Option A and B.
Archaea and bacteria are prokaryote and reproduce by binary fission.
Explanation:
Archaea are grouped of single celled organisms that have no cell nuclei. They are prokaryotes and reproduce by binary fission. They were formally grouped as bacteria with the name archaeabacteria but the classification is outmolded. They are now renamed as archaea bacteria as they are closely related to eukaryotes.
Bacteria also are single celled, microscopic organisms. They are prokaryotes and they reproduce by binary fission. They have are number of shapes ranging from spheres to rods.
