​A mutation has occurred that has changed the codon CGC to CCC? What affect will the mutation have on the protein?

The mutation leads to apoptosis in p53 mutant cells

Explanation:

This mutation is basically the point mutation where CGC-arginine mutates to CCC-proline.  The major difference between the two is presence of codon 72 of the p53 gene . This codon in p53 leads to  apoptosis in p53 mutant cells

yes its like the dead sea which is full of salt which makes you stay afloat

so yes an egg will float in salt

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
