Soap and detergent molecules have a long, hydrophobic "tail" and a polar, hydrophilic "head." they are sometimes referred to as "bridge molecules" because they allow oils and fats to be suspended and "dissolved" in water (which they otherwise would not be able to do). imagine that you are using soap to wash away dirt that is being held against your skin in an oily film. in this scenario, how are the soap, dirt/oil, and water arranged at the molecular level?

The answer is The soap molecules encase the dirt/oil within a small droplet that has a water-loving exterior and a water-repelling interior

Soap has hydrophobic "tail" and a polar, hydrophilic "head". The hydrophobic tail would be able to attach to the lipid. This will make the soap encase the dirt/oil with theil tail inside. The hydrophilic head will be on the exterior, which will make a structure a kinda look like polar and could dissolved into water.

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
