Answer:
Dimers, trimers, and tetramers are, for instance, oligomers composed of two, three, and four monomers, respectively. In biochemistry, an oligomer usually refers to a macromolecular complex formed by non-covalent bonding of a few macromolecules like proteins or nucleic acids.
Explanation:
Answer:
The answer to these questions are the following:
1. sucrose solution (higher concentration of water molecules in the onion cells) >> red onion cells will shrink >> smaller diameter
2. distilled water (higher concentration of water molecules in the surrounding solution) >> red onion cells will become turgid >> higher diameter
Osmosis refers to the movement of a solvent (usually water molecules) across semipermeable biological membranes, which occurs from a region of higher concentration to a region of lower concentration. There are three classes of solutions that have different effects on cells due to the process of osmosis:
1. In a hypotonic solution, the cells will become turgid
2. In an isotonic solution, the cells will become flaccid.
3. In a hypertonic solution, the cells will shrink (plasmolysis)
When plant cells are placed into a hypertonic solution where there is a greater concentration of solute outside the cells (as in this case sucrose solution), water molecules will move from inside the cells to outside the cells, thereby cells will shrink due to water loss
When plant cells are placed into a hypotonic solution that is diluted in comparison to the content of the cell (as in this case plant cells placed in distilled water) water molecules will move from outside the cells to inside the cells, thereby cells will become turgid.

Sexual reproduction is the process in animals that requires meiosis to take place. It does not matter whether the animal is single celled or multi celled. Meiosis is the type of cell division in which four daughter cells are formed with half the number of chromosomes of the original orthe parent cell. The perfect example of meiosis is the formation of gamets and spores. Meiosis is the process that helps in the formation of male and female reproductive cells like the sperm and the eggs. Meiosis is totally different from mitosis.
Transportation is the cells way of brining in and expelling molecules, ions, et cetera. This is useful because a cell can receive what it needs at all times via transport but also have the ability to rid the cell of unnecessary molecules that aren't needed.
They show how much one variable is affected by another.
