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.
Answer:
The correct answer is b. an amino acid
Explanation:
A tRNA is called adaptor RNA which have cloverleaf-like secondary structures. These structures contain stems and loops which make up the acceptor arm, anticodon stem and loop, D- stem and loop, and T- stem and loop.
Acceptor arm contains seven base pairs and four single stranded nucleotide which include conserved CCA sequence. The function of acceptor arm is attach amino acids require for protein synthesis.
The anticodon loop gives information to acceptor to attach a specific amino acid according to the sequence present in mRNA. The first amino acid which attaches to acceptor arm is methionine.
Thus, the correct answer is b. an amino acid.
a change in a population's allele frequencies
