The answer is (b). The hydrophobic sequence of AA is not electrically charged so it isn't soluble in water that means it spans the membrane. The
hydrophilic sequences are attracted by water and they remain in the aqueous enviornments on the two sides of the membrane. This diagram should clarify.
This seems to be the best answer: C. The data does not take into account underground growth and the actual area of fungus spread may be larger, so the original conclusion of the experiment is not accurate.
Pollution; waste and discharge falls into the water, polluting the sea grass. It reduces the amount of sunlight and the plant might die.
Poor land management; trees lead to the erosion of dirt, making the soil cloud up the water, not giving the sea grass sunlight.
Careless behavior; from people stepping onto the sea grass, to other items falling and smothering the sea grass.

Options for the question are not given. They are as follows:
a. arg or lys
b. ala
c. thr
d. leu or ser
e. Only termination codons
Answer:
d. leu or ser
Explanation:
Four codons code for proline amino acid. These are CCT, CCC, CCA, and CCG. Hydroxylamine causes C to change into T or G to change into A.
If first position is changed in each codon:
CCT = TCT (UCU)
CCC = TCC (UCC)
CCA = TCA (UCA)
CCG = TCG (UCG)
These codons produce Serine amino acid.
If second position is changed in each codon:
CCT = CTT (CUU)
CCC = CTC (CUC)
CCA = CTA (CUA)
CCG = CTG (CUG)
These codons produce Leucine amino acid.
Hence, out of the given options, option d. leu or ser is correct.
Amino acids are the building blocks of proteins. Amino acids polymerize together into protein strands.
