Explanation:
<span>The sex cells, more scientifically known as the ova and spermatozoa, are composed of 23 of the usually 46 human chromosomes. They have half the usual number because they of course combine to form a new, genetically distinct, cell, termed the zygote. The correct term for this type of cell, one with half of the complete genome, is GAMETE. Therefore the answer is option (a).</span>
If the same protein keeps being produced it could be said that nothing is happening even though something happened, and if nothing is changing you could say that it is a silent mutation, which means that the answer is C.) Silent. The change in the amino acids and the nucleotides happened but it is silent and does not affect the outcome of the protein synthesis.
Most probably these scientists will do more studies and experiments in order to learn more about the subject. For example, if they compare plastic grocery bag with paper grocery bag it is important to investigate which one is a better resource use in the life cycles, which one is better for manufacturing or whether one of them can be reused. There are many questions about this issue.
