Biomass is the total mass of a specific organism in the area. If there is a negative value of change in shoot biomass, that mean the mass of the shoot in this period are less than before. This indicate increases in predation/death which reduce the population of the shoot more than its growing rate. The cause could be an increases in predator population or decreases in food/resource.
D. It must go from areas of low concentration to high, and this is only achievable with the use of energy, ATP!
Answer and Explanation:
UGA, UAG and UAA are the stop codons in the genetic code. During translation, these stop codons signal the end of the polypeptide chain. These codons do not code for an amino acid. Therefore they are called termination codons or nonsense codons. These stop codons have been called as ochre (UAA), amber (UAG) and umber or opal (UGA). Richard Epstein and Charles Steinberg revealed Amber (UAG). They named it amber while remaining two stop codons named as ochre (UAA) and opal (UAG) to maintain the theme of ‘colors names’. Stop codons release the new polypeptide chain from the ribosome, during protein synthesis. This happens because there are no tRNAs with anticodon corresponding to the stop codon.
