7. You are stranded on an island covered in
vegetation. To escape, you decide to build
a raft out of layers of reeds and small
branches.
(a) Would it be better to line up the reeds in
each layer and tie them together, or to
crisscross them and weave them together?
(b) Would it be better to line up the reeds in each layer in the same direction as the layer below, or should the reeds in each layer point in different directions, explain.

A. Criss-cross them and tie them together

B. Your raft would hold up better if you made them almost on top of each other in different directions otherwise you face them in the same direction your sticks would just fall flat

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
