The length of the hockey stick is generally the easiest to determine, but imperative for a playerâs success in the game. Sticks usually come in four sizes: senior, intermediate, junior and youth. Each size normally reflects a smaller shaft circumference and a softer flex.
Factors in the environment may influence the rate of mutation but are not generally thought to influence the direction of mutation. For example, exposure to harmful chemicals may increase the mutation rate, but will not cause more mutations that make the organism resistant to those chemicals.In this respect, mutations are random  whether a particular mutation happens or not is unrelated to how useful that mutation would be.actors in the environment may influence the rate of mutation but are not generally thought to influence the direction of mutation. For example, exposure to harmful chemicals may increase the mutation rate, but will not cause more mutations that make the organism resistant to those chemicals.
Gene mutation may lead to alter the number or the structure of the entire chromosome, which could lead to chromosomal mutations. However, gene mutations are small-scale alterations in the nucleotide sequence and those are sometimes corrected through gene regulatory mechanisms but sometimes not.ome of the problems that are evident of a gene mutation cause are the sickle cell anaemia and lactose intolerance. Chromosome Mutation. Chromosome mutation is a large-scale alteration of the chromosomes of an organism, where either the number or the structure of chromosomes is changed.
