How does shell color work to protect the egg from sunlight?

Birds that live in cool climates lay darker eggs, as darker colors absorb more heat from the sunlight

Birds that live in hotter climates lay lighter eggs to prevent the egg from overheating.

The pigmentation acts to thermo-regulate the internal temperature of the egg, acting as a buffer between the embryo and the outside world. It does this by preventing overheating of the egg, through reflecting the sunlight off the pigmentation, rather than allowing it to be absorbed through the shell

layer 3 is younger than layer 6.

ans.

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.'
