Pesticides include herbicides, fungicides and insecticides. Pesticides can be used safely for the non target organisms but under normal use conditions only.
Thus, the correct answer is option (D).
In every trophic level, only 10% of energy is passed on.
Grass, with <span>30,000 kJ of energy, is eaten by a zebra.
Zebra then has 10% of 30,000 kJ from the grass, which is 3,000 kJ of energy.
Cheetah then eats the zebra, gaining only 10% of 3,000 kJ of energy of the zebra. Finally as conclusion, cheetah has 300 kJ of energy after having acquired the zebra.</span>

Label C is the carboxyl group
Explanation:
a star expels most of its outer material until only the hot core remains, which then settles down to become a young a white dwarf
The right answer is 20 aminoacids per second.
Transcription is a mechanism for synthesizing RNA from DNA.
Translation is a mechanism for synthesizing a polypeptide sequence from mRNA by converting the nucleotide triplet (codons) to amino acids.
So if one amino acid corresponds to three nucleotides. The polypeptide synthesis rate should be 20 amino acids per second for 60 nucleotides per second.
3 nucleotides ==> 1 amino acid
60 nucleotides ==> 60/3 = 20 amino acids.
