Use the picture below to answer the following question. what is the probability that the f2 generation will have red eyes?

The representation of the genotype of F1 generation is as follows:

Heterozygous red eye: Rr

The red eye is the phenotype and Rr is the genotype of F1 parental generation.

In F2 generation, the number of offspring that will have red eyes can be predicted by punnet squares represented in the image.

Offspring that are homozygous recessive (rr): 1 out of 4 or 1/4= 25%

Offspring that are heterozygous or homozygous dominant for red eyes (Rr and RR): 3 out of 4 or 3/4= 75%

Therefore, the probability that the F2 generation will have red eye is 3/4 or 75%

answer is

human impact on the environment can be seen in the deterioration of the !

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."
