Arisk is something that causes the possibility of a loss. a. true b. false

Correct  A.  True

Explanation:

The dictionary definition of a "risk" is that someone or something of value is exposed to danger, harm, or loss (Oxford Living Dictionaries).

Having said that, we should also note that without risk, there often is little or no reward.  Sometimes taking a risk is necessary in order to achieve a gain. If I hide all my money under my mattress to avoid the risks associated with investing money in banks or the stock market, I don't gain any interest or growth on my dollars.  If I won't get in a car or on an airplane because of the risks associated with automobile travel or air travel, I isolate myself and don't get to visit people and places beyond my immediate neighborhood.

Risk assessment and risk management will mean that we will assess the real risks of situations and activities, and balance those against potential rewards. We will take appropriate precautions and safeguards before taking a risk.  For instance, if a child wants to learn how to ride a bike (which will bring the rewards of a fun and healthy activity), parents will make sure the child wears a helmet and possibly knee and elbow pads.  They will start with training wheels or by going alongside to guide the bike before having the child attempt riding fully on their own.

A. True

Explanation:

a and b

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
