Bacteria: are single-celled microscopic organisms that are characterized by the presence of incipient nucleus and few membrane-less cell organelles.
Fungi: are eukaryotes that are characterized by the presence of chitin in the cell wall.
Cell Type: All bacteria are prokaryotes. All fungi are eukaryotes.
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.

The answer is d. the medical team looks as which kind of wbc's are present, when that is discovered, an appropriate antibiotic is perscribed.
A. Ribosomes
Ribosomes bind mRNA and translate into a protein. They reside in the cytoplasm and bind to the endoplasmic reticulum.
D. The chromatin coils and condenses into visible chromosomes.
