Mendel's principle of dominance suggests a (recessive, diploid, dominant) gene will always be masked by the presence of a (recessive, haploid, dominant) gene.

The correct answer for the blanks are-

1) Recessive gene

2) Dominant gene

Explanation:

According to Mendel's principle of dominance, offsprings with heterozygous genotype (that is having two different alleles, dominant and recessive) exhibit the phenotype of dominant allele as it masks the expression of recessive allele.

Thus, a recessive allele (such as t for dwarf plant) will always be masked by the presence of dominant allele (such as T for tall plant).

Therefore, a Tt (heterozygous pea plant) genotype plant will express tall trait and mask dwarf trait.

Thus, according to this law, the right answer for blanks are-

1) Recessive gene

2) Dominant gene.

"-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."
