Ans.
The codons show genetic codes, made up of triplet of nucleotides in DNA or RNA that code for specific amino acids. The different codes can code for a same a amino acid. When a substitutional mutation occurs in genetic material, it shows substitution of one nucleotide pair for another and leads to formation of a different codon.
The first mutation that leads to CAU to CAC, it will not show any potential damage as both CAU and CAC codons code for histidine amino acid.
The second mutation that leads to UGU to UGC will also not show any damage to protein as both of these codons code for cysteine amino acid.
The third codon, that results UCU to UUU will cause a potential damage to protein as UUU codes for phenyl alanine (an aromatic, non-polar amino acid) and UCU codes for serine (a polar amino acid).
Thus, the correct answer is 'option C).' as in a protein, substitution of serine with phenylalanine will lead to change in structure and function of that protein.
The correct option is TRIGGER. Triggers are events or things presently occurring that make one to remember past trauma which are associated with negative emotions. Triggers usually bring forth negative emotional responses and most people usually avoid situations that will trigger them to remember things that are better forgotten.
Better crop yields and reduction of the chance of pests destroying a crop is benefit of introducing variety of plants to farm.
<h3>What is plant breeding?</h3>
plant breeding is the process of produce crops to keep their qualities and improve new qualities.
Plant variety is the result of Plant Breeding. Introducing n new varieties requires skills, time, money and material .
The new varieties help to enhanced the growth of agriculture, improve plants, resist diseases and also help to boost several emerging economies countries.
Therefore, Better crop yields and reduction of the chance of pests destroying a crop is benefit of introducing variety of plants to farm.

Answer:
NITROGEN-11:
PROTONS:7
NEUTRONS:11-7=4
ELECTRONS:7
NITROGEN-14
PROTONS:7
NEUTRONS:14-7=7
ELECTRONS:7
NITROGEN-25
PROTONS:7
NEUTRONS:25-7=18
ELECTRONS:7
EXPLANATION
NUMBER OF PROTON = ATOMIC NUMBER IN PERIODIC TABLE
NO. OF ELECTRON= NO.OF PROTONS
NO. OF NEUTRON = MASS NUMBER - PROTON NUMBER
#MASS NUMBER IS GIVEN IN NAME OF ISOTOPE
NITROGEN -11 HAS MASS NUMBER 11
