Plz me real quick i completely forgot about this and it's due today

answer: 1. i think its important for teens to learn about that bc then they can think and realize that they need to use protection when having sex, otherwise he might get the girl pregnant without knowing it, and she could go through with an abortion which would bring regret later or she could be stuck being a teen mom.

2. idk really know, but it should include both pair giving back to each other and it should be 2 sided, unhealthy would be having a 1 sided relationship.

3. if its uncomfortable the you should try going to a parent or trusted adult, dont go to a friend, friends wont give you the right answer, thats why you need to go to someone who knows what they're saying.

explanation:

where is the option.let me know

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
