Answer:
The reaction that triggers a firework to detonate needs less energy to initiate and occurs at a quicker pace than the one that causes a candle to burn.
Explanation:
The rate of a chemical reaction and the energy input required for that reaction are closely related to the concentrations of the reactants within the system. Therefore, we can deduce that a higher concentration of reactants leads to a faster reaction because of the increased likelihood of molecular collisions.
Even though the candle burning reaction involves more reactants than the fireworks explosion, it requires less energy to ignite. This attribute enables the molecules of the reactants to move faster and collide more effectively, resulting in a faster reaction.
In conclusion, the initial energy needed for a firework to explode is smaller, and the reaction proceeds more swiftly compared to that of a burning candle.
The most effective method to eliminate dangerous germs that could be in meat is to: ensure it is cooked to a safe minimum internal temperature.
Additional Details
Meat is classified as a potentially hazardous food, meaning it can harbor microorganisms including disease-causing bacteria. This vulnerability arises because of meat's properties—its high moisture content, protein levels, and favorable pH all support the growth or toxin production of harmful bacteria. Consequently, food safety agencies mandate control of time and temperature when handling this type of food.
Time-Temperature Control (TCS) is essential to keep food safe by either slowing bacterial growth or eliminating bacteria through proper heat treatment.
Freezing
Freezing alone does not kill pathogenic bacteria or their toxins but only renders bacteria inactive, preventing toxin production. Thus, if contaminated food is frozen and then thawed, the harmful bacteria remain. Most bacteria become inactive below 40 °F.
Cooking
When preparing raw meat and poultry, it is crucial for cooks to verify that the internal temperature reaches the safe minimum level and observe the required rest time. Using a food thermometer is necessary to check this. For roasting, the oven temperature should not be below 325 °F. Proper cooking to the safe minimum temperature effectively destroys dangerous bacteria responsible for foodborne illnesses.
Safe Minimum Internal Temperature and Rest Time for Meat
- All poultry (whole, chopped, stuffed, or minced) - 165ºF
- Beef, pork, veal, lamb (chops, roasts, steaks) - 145ºF plus 3 minutes rest time
- Minced meats - 160ºF

Sterol and stanol esters, commonly known as phytosterols which aid in lowering LDL cholesterol or blood cholesterol levels. The LDL is often referred to as harmful cholesterol.
Answer:
B
Explanation:
This is due to the fact that the muscle cells in humans consist of actin and myosin protein filaments, which contain nitrogen molecules. Thus, the radioactive nitrogen would likely be present here.
