Rose comb (R) in chickens is dominant over single comb (r). Cross a white heterozygous rose comb chicken to a black single comb chicken.

What is the genotype of the white heterozygous rose comb chicken?

What is the genotype of the black, single combed chicken?

What fraction of the offspring will be blue rose comb?

What fraction of the offspring will be blue?

What fraction of the offspring will be single comb?

What fraction of the offspring will be white rose comb?​

idk

the backbone of the dna and rna compound is sugar phosphate.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."    

do yall know the answer?
