During DNA renaturation, two DNA strands will:

a. break the hydrogen bonds that hold the two strands together with no effect on the covalent bonds that hold the nucleotides together.
b. break the covalent bonds that hold the nucleotides together while maintaining the hydrogen bonds that hold the two strands together.
c. Re-form a double helix if the two strands have complementary sequences.
d. Re-form a double helix if the two strands are identical in sequence.

Use this new information to determine the parents’ genotypes (indicated by red arrows). then calculate the probabilities that the second male offspring will have each condition. drag one pink label to each pink target and one blue label to each blue target. then use the white labels to answer questions 1 and 2. labels can be used once, more than once, or not at all.

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.

Advances in technology have enabled scientists and researchers to better study the evolutionary relationships between species
