question 4 (multiple choice worth 2 points)
which of the following statements best describes the structure and function of a carbohydrate?
carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.
carbohydrates are made up of starchy monomers and are used for structure, protection, and reproduction.
carbohydrates are long, winding molecules made up of amino acids and are important in the synthesis of fats and hormones.
carbohydrates are made up of sucrose molecules that are important for transportation and protein synthesis.
question 5 (multiple choice worth 2 points)
some snake venoms are harmful because they contain enzymes that increase the rate of a reaction that destroys blood cells and tissue cells. the damage caused by such a snakebite could best be slowed down by
applying ice to the bite area in order to decrease the temperature of the cells
inducing vomiting in order to remove all of the stomach content
drinking large amounts of water in order to hydrate the cells
elevating the bite area in order to increase the number of blood cells present
question 6 (multiple choice worth 2 points)
dna and rna are both
made up of nucleotides and carry molecules from one end of a cell to another
monomers of protein molecules that provide structure to a cell’s nuclear membrane
protein molecules that carry the unique genetic information of an organism
molecules that contain genetic information and are made up of nucleotides
