How many total amino acids are there to build all the different proteins in organisms?

There is one amino acid for each protein and the amount of amino acids depends on where your start and end codons are. If you know where your start and end codons are, count 3 letters, (i.e. AGC), then move to the next three. Start from the start codon and for every three letters, there is an amino acid.

Hope this helped!

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

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.
