Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
Answer:
There are no options to this question, however, it can be answered. The answers to the blank spaces are:
1. Fatty Acids
2. A decrease in the rate of lipid breakdown
Explanation:
Lipids are large biomolecules that are formed from monomeric units called FATTY ACIDS. Digestive enzymes such as lipase as described in this question breaks down lipids into its monomer called FATTY ACIDS.
However, enzymes are proteinous molecules, meaning they are subject to denaturation when exposed to adverse conditions such as heat. According to this question, the scientist heats the enzymes and finds that it can't bind onto the lipids anymore because it has been DENATURED. This situation will result in the DECREASE IN THE RATE OF LIPID BREAKDOWN because the enzyme in charge is no longer functional.
Answer:
If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children
Explanation:
Even tho the cause of lung cancer is not very clear, a genetic predisposition is of a great influence, his smoking and therefore causing a lung cancer is not appliable to his children because of no connection, but in the sense of having a mutation which makes you predisposable to the cancer with or without the smoking, can lead to a high risk of gene inheritance and therefore inheriting the mutation with a high risk of getting lung cancer excluding the smoking.
