Answer:
They help transport materials that an organism needs to survive and they recycle waste materials.
Explanation:
I hope this helps! :))
Answer:
Explanation:
This is because they are simpler molecular structure,with C-H bonds compare to polysaccharides which are aggregate of monosaccharide formed by glycosidic bonds.(covalent bonds) through condensation(This is the loss of OH and H from sugar molecules involved) the differences in strength of the two bonds is the reasons.

A sugar phosphate backbone joins the nucleotide in a DNA sequence. A double helix has TWO backbones.
Answer:
Because no herbivores would want to eat it, and it could ward most predators away easier.
Thick myosin filaments of muscle are associated with the characteristics of contractility.
Explanation:
The muscle contractility is provided mainly the thick and the thin muscle filaments. Thick muscle filaments are constituted by the contractile protein, myosin. Thin filament is composed of actin.
Owing to its thickness, myosin protein is made up of six chains of polypeptides with four lighter (molecular mass is low) ones and two heavier (molecular mass is high) ones.
The two heavier polypeptide chains twist together like two twisted golf clubs and forms a coiled-rod like structure. This coiled structure looks like a two stranded double helix.
The globular heads point out from the main body in each coiled structure and adheres with the head of the actin filaments. The tails made up of lighter chains point towards the M lines of the sarcomere.
During muscle contraction, the myosin head will attach with its myosin-binding site.
