Apolypeptide in a wild type microbe contains the sequence leu-pro-tyr-ser-pro. a phenotypic variant of the species has the peptide sequence leu-pro-cys-ser-pro. this is an example of a(n) mutation.

 The answer is a misense mutation. In this case, the substitution of the tryosine  amino acid with cysteine in the same position in the sequence does not affect the polypeptide becasue both tryosine and cysteine are polar animo acids. If the substitution in the polypeptide chain was by amino acids with different properties, it would affect the folding of the protein and change its conformation hence also affect its function. 

correct answer: false

while planning water activities, it is very important to consider the weather, because if we do not plan and are going for a surf, then it might be that the hurricane came and drown us or may carry us to long distance from where we can not come back. there are many reasons to take information about the weather when we are planning any water activities.

hence, the correct answer would be false.
