Biology Qs

Ca2+ ions have two fewer electrons, giving them a positive charge. They are most likely to form ionic bonds.

Suspension: heterogeneous, solute un-dissolved and will settle (examples: blood, cytoplasm). Colloidal: solute equally distributed but not entirely broken down (examples: insulin, gelatin). Solution: solute entirely dissolved/evenly dispersed in solvent (examples: urine, synovial fluid).

Surface tension, caused by polar attraction between the different molecules.

DNA loses its structure and therefore ability to replicate without phosphorous. It is also essential for energy storage (ATP/ADP) and bone growth and health.

One way to make such a division is based on the function of these molecules within the body; lipids, proteins, and carbohydrates are all ingested and generally used as fuel for the body, whereas nucleic acids perform a different function. Molecular structure could also be used: nucleic acids, proteins, and lipids are all chain molecules, carbohydrates are not.


The membrane is fluid in that various substances can pass through it, so it is not solid, and a mosaic because it is composed of many different heterogeneous elemnts.
