The purpose is to help you estimate the total distance because a map is zoomed out so they need to scale it down so its small and the scale helps make the distance accurate.
Answer:
Dude this one is confusing because you are not giving the price of the object.
Explanation:
Answer:
habitat destruction, overexploitation, climate change, nitrogen pollution, and invasive species.
Explanation:
Main Modern Causes of Extinction:
habitat destruction - the process by which a natural habitat becomes incapable of supporting its native species.
overexploitation - harvesting a renewable resource to the point of diminishing returns.
climate change - includes both global warmings driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns.
nitrogen pollution - a form of water pollution, refers to contamination by excessive inputs of nutrients.
invasive species - an introduced organism that negatively alters its new environment.

Answer:
CH3CHCHCOOH : 11 sigma and 2 pi bonds
HCCCH2CHCHNH2: 12 sigma and 3 pi bonds
H2CCHCH2CCH: 10 sigma and 3 pi bonds
Explanation:
>In this carboxylic acid there are 11 sigma bonds between C-H, C-C ,C-O and O-H atoms,while there are two pi bonds ,one is made by carbonyl carbon and other from alkene C=C carbons
> In this amine there are 12 sigma bonds made by C-C,C-H and N-H atoms,while 2 pi bonds made by alkyne carbons C≡C carbons and 1 pi bond is made by alkene C=C carbon atoms
>In this organic molecule there are 10 sigma bonds made by C-C and C-H bonds ,while 2 pi bonds made by alkyne carbons C≡C carbons and 1 pi bond is made by alkene C=C carbon atoms.
