Final answer:
The action performed by oxidative color after initial application is the gradual development of color. In triglyceride degradation, the first step is the removal of fatty acids before they undergo β-oxidation.
Step-by-step explanation:
The action performed by oxidative color after initial application is B) Gradual color development. Oxidative colors contain small, colorless molecules that, when combined with an oxidizing agent, usually hydrogen peroxide, undergo a chemical reaction that turns them into larger, colored molecules. This process develops gradually as the molecules react and bond within the hair shaft, leading to the permanent alteration of hair color.
Regarding the first step in triglyceride degradation, the correct answer is A. removal of fatty acids. The triglycerides first undergo hydrolysis, where each triglyceride molecule is broken down by enzymes into glycerol and free fatty acids. After this, the fatty acids can enter the process of β-oxidation, which takes place in the mitochondria where these fatty acids are further broken down to generate acetyl-CoA units, which are then used in the citric acid cycle to produce ATP.
