For many generations, the following genotypic frequencies were observed in a large population of dinosaurs: 4 percent aa, 32 percent aa, and 64 percent aa. the climate changed abruptly and resulted in the death of all homozygous recessive dinosaurs (s = 1). in the next generation, the recessive homozygotes died shortly after birth. what percentage of these newborn dinosaurs died? show calculation
a) 4% b) 8.5% c) 19.7% d) 36.8% e) 44%

C) 19.7%

Explanation:

The new population distribution after climate change wiped out homozygous recessive dinosaurs is:

The percentage of offspring of this new population that are homozygous recessive is given by:

19.7% of these newborn dinosaurs died

this would be a math

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
