<span>The amount of energy at each trophic level decreases as itmoves through an ecosystem. ... An energy pyramid is a model that shows the flow of energy from one trophic, or feeding, levelto the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level.</span>
Answer:
Due to the cost and resource input (specially the land) required for producing ethanol
Explanation:
In current time most of the ethanol is produced by fermenting corn, sugarcane or other plants at high temperature. In this process of fermentation, liquid bio fuel is produced.
These plants and crops require large area for cultivation and production along with huge inputs of fertilizers and water. As per an estimate , 3 gallons of ethanol require bushel of corn that intakes 800 gallons of water which is a huge cost to any nation or individual
Hence, scientist are finding new ways to create ethanol
Answer:
The complimentary strand of codons would be CAG-UAC-AAA-UCA-AGG-GAU-AUC.
Explanation:
C (Cytosine) pairs to G (Guanine).
Think of it as *C*ar in the *G*arage.
A (Adenine) pairs to U (Uracil).
Think of it as *A*pples *U*nder the tree.
Answer:
A new mutation
Explanation:
A mutation refers to the random changes in the DNA of organisms. A mutation changes the allele and genotype frequencies by the introduction of a new allele in the gene pool.
However, mutations are not the major factor responsible for changes in the gene pool of a population as mutations are rare. The rate of mutations is very slow and does not allow it to serve as a major factor to change the allele and genotype frequencies.
