NGSS.HS-LS1-6

• protein

• nucleic acid

• lipid (steroid)

• carbohydrate

Answer explanation

lots of points which means lots of carbons but there are no oxygen's attached to each carbon so it can't be a carbohydrate.

• nucleic acid

• lipid

• carbohydrate

Answer explanation

Every carbon (point on the hexagon) has an oxygen attached = carbohydrate. If there were not oxygen's on each carbon then it would be a lipid.

Answer explanation

Notice how all carbons have an oxygen attached this is an indicator that it is a carbohydrate.

• protein

• nucleic acid (ATP)

• lipid

• carbohydrate

Answer explanation

You should see a nitrogen base on the right and THREE phosphate groups on the left with sugar in the middle. The nitrogen base is what gives the group away.
