glucose, a monosaccharide, is found in three different polysaccharides: starch, glycogen, chitin. there are differences between
the structure and function of the glucose arrangement found in these polysaccharides. which statement correctly identifies
the difference in glucose structure in one of these polysaccharides?
a) glucose molecules are joined in a long chain to make starch that is easily digested for energy
b) glucose molecules are joined in long branched chains to make glycogen that allows for long term energy storage in animals
c) glucose molecules are joined in long chains with hydrogen bonds connecting multiple chains to make cellulose which is easily broken down for quick digestion
d) glucose molecules with attached amino groups are joined in long chains by a peptide bond to make chitin which makes up the cell wall of some bacteria and fungi

Acar company is testing seatbelts using crash test dummies. the company finds that when cars come to a sudden stop, the crash test dummies' bodies continue to move forward. the seat belt keeps the crash test dummies from hitting the back of the seat in front of them. why do the crash test dummies' bodies continue to move forward even though the car stopped? a. the friction opposing their bodies' movement keeps them in motion. b. the inertia of their bodies keeps them in motion. c. the forward acceleration of the car keeps them in motion. d. the gravity pulling on the car keeps them in motion.

1. variations in a population of moths allow for some of its members to be able to adapt to environmental changes. the better adapted of the moths will be able to survive the change and thus prevail as the “fittest” of the species. (a) describe three mechanisms in which variation can occur within a species population. (b) explain which mechanism or mechanisms would be responsible for the survival of a population of peppered moths better than white moths in an environment affected by industrial soot. justify your answer.
