A point mutation can either be silent, missense, or nonsense. In silent mutations, the codon is changed but the encoded amino acid is not changed. This is because different codons code for the same amino acids. Missense mutations will have a significant effect on the protein because the amino acid is replaced by another. A nonsense mutation will result to a fragmented protein because the mutation will lead to the formation of a stop codon which will stop the translation process.

. Growing two plants without plant food at all doesn't count; in order to see if the new food is better, he must also grow plants with the original food in order to compare it.
have an independent variable. This is the type of plant food. It's independent because he has direct control over it.give plants the same conditions besides food: same water (amount), same light exposure, same temperature, etc.
choose a quantitative way to measure how much the plants grew, like mass or length.i need brainlest anwser to rank up help
