Many snakes and lizards live in the desert, where temperatures are high during the day and cold at night. How does the temperature range affect the size of the snakes and lizards? A. High daytime temperatures allow them to grow as large as the food supply will allow.

B. Cold nighttime temperatures limit their size, because large ectotherms need a long time to warm up in the sun.

C. High daytime temperatures limit their size, because large endotherms would overheat on very hot days.

D. Cold nighttime temperatures limit their size, because large endotherms would lose too much of their body heat.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
