Saturated fats found in animal products, such as bacon and cheese, are also called lipids. Correct answer: D
Lipids are group of organic molecules that include fatty acids (fats), oils, waxes and steroids, such as cholesterol. Saturated fats are found mainly in animal foods such as beef, pork, lamb, butter, milk and cheeses ans studies show that they the primary cause of elevated blood cholesterol.
Saturated fats found in animal products, such as bacon and cheese, are also called triglycerides.
Triglycerides are a type of lipid, which is a broad term used to describe various types of fatty substances. Lipids are an essential component of our diet and play important roles in the body, including providing energy, insulating and protecting organs, and aiding in the absorption of fat-soluble vitamins.
Triglycerides consist of three fatty acid molecules attached to a glycerol molecule. When all the carbon atoms in the fatty acid chains are bonded to hydrogen atoms, the fat is considered saturated. This means that the fat molecules have a straight structure and are typically solid at room temperature.
Animal products, such as bacon and cheese, are known to be high in saturated fats. Consuming excessive amounts of saturated fats can contribute to increased levels of cholesterol in the blood, which is associated with an increased risk of cardiovascular diseases.

Muscle stiffness is multifaceted and can result from factors such as overworked muscles, cellular damage after intense exercise, improper alignment of joints, lack of warm-up before exercises, and myosin heads not detaching from action-binding sites. Muscles gain mass as the damage is repaired, a process called hypertrophy. This contrasts with the atrophy process where sarcomeres and myofibrils disappear but the number of muscle fibers remains.
Stiff muscles do not only result from overworking them but can be due to various factors. Improper resistance training, for instance, can lead to overused muscles, tendons, or bones resulting from too heavy loads or insufficient recovery time between workouts. Other causes include cellular damage to muscle fibers after intense exercise and joints not properly aligned. Besides, the condition of muscles being rarely completely relaxed or flaccid also contributes to muscle stiffness.
However, it's worth noting that muscles gain mass as the muscle damage is repaired, and additional structural proteins are added to replace the damaged ones. This is referred to as hypertrophy. The opposite process - atrophy, results in the disappearance of sarcomeres and myofibrils but not the number of muscle fibers, which can be observed when a limb casts are removed or in diseases like polio.
Everyday activities, such as exercise and stretching, matter too. Warm-up exercises increase blood flow to the muscles while stretching helps pull on the muscle fibers. Absence of a proper warm-up can result in damage to muscle fibers or a pulled tendon. Lastly, myosin heads not detaching from actin-binding sites results in muscle stiffness, causing conditions like 'writer's cramp' or rigor mortis in a recently deceased person.

Three ways to protect oneself from the sun is;
1. Wearing sunscreen protection
2. Wearing sunglasses, long sleeves, and a hat
3. Getting outdoors before 10 am and after 4 pm when the sun rays are least strong
When sun rays hit the skin, a cascade of biochemical pathways is significant in the uptake of vitamin D from the gut. Vitamin D is important in the absorption of calcium and minerals into bone and making them strong. This prevents diseases such as rickets.
