4After completing their study of the carbon cycle, three students wrote statements making claims related to this topic. Read eac
mario62 [17]

Answer:

Incorrects:

Claim 1: When forests are cleared, we take away an opportunity to remove carbon from the atmosphere.

Claim 2: Carbon moves through biological systems and returns to the atmosphere through photosynthesis.

Claim 3: The amount of carbon involved in rapid cycling is much less than 1 percent of the total amount of carbon on Earth.

Explanation:

  • The carbon contained in forest products makes a small and manageable contribution to the global carbon balance.  Globally, the net effect on atmospheric concentration is negligible, unless the rate of decomposition in geographically displaced product stocks is different from that in the forest ecosystem from which it was removed. However, controlling these rates through proper management can lead to some degree of mitigation of increases in atmospheric CO2.
  • During the carbon cycle, animals and plants release carbon dioxide into the atmosphere through cellular respiration, and plants capture carbon dioxide through photosynthesis.
  • The amount of carbon involved in rapid cycling it is the largest since it includes the carbon exchange between living beings, and is intertwined with the carbon cycle through long-term geological processes

Which statement is scientifically based?
Nastasia [14]

I would wait for a second opinion, because the question is phrased in such a way that is confusing.

None of the statements contain scientific evidence except for the last one, but the last statement is false.

If you were being scientifically accurate, you would answer the first statement as true and the rest false.

The second statement actually has evidence to back it up, but the evidence provided is incorrect.

co-dominance is the answer because  


Inheritance of Dwarfing in Maize. Demonstrating the heights of plants from the two parent variations and their F1 heterozygous hybrid (centre).


Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus.[1][2] The first allele is dominant and the second allele is recessive. For genes on an autosome (any chromosome other than a sex chromosome), the alleles and their associated traits are autosomal dominant or autosomal recessive. Dominance is a key concept in Mendelian inheritance and classical genetics. Often the dominant allele codes for a functional protein whereas the recessive allele does not.
