An alien species has two alleles for antennae shape: flat (f) and round (f). the flat (f) allele exhibits complete dominance, the round (f) allele is recessive. create a punnett square in your notes, and explain the probability of a baby alien having round antennae, if one of the parents had heterozygous dominant (ff) alleles, and one parent had homozygous recessive (ff) alleles.

"do a testcross with a homozygous recessive plant."

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.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.

the answer would be   10%
