When a facial muscle contracts habitually, it undergoes shortening. However, the skin above the muscle does not shorten in the same way. This difference in shortening between the muscle and the skin causes a line to form on the skin's surface. Therefore, the statement is true.

Antioxidants are substances that can prevent or slow damage to cells caused by free radicals, which are unstable molecules that can harm cells and contribute to the development of various diseases. By neutralizing free radicals, antioxidants help protect the body from oxidative stress and reduce the risk of chronic conditions such as heart disease, cancer, and inflammation. Therefore, it is correct to say that antioxidants block free radical damage.

Cross-linking is a chemical process that occurs in the presence of oxygen, leading to the formation of undesirable bonds. This process can happen in various materials, such as polymers, where the oxygen molecules can react with the polymer chains and create additional bonds between them. These undesirable bonds can alter the properties of the material, making it less desirable or even unusable for certain applications. Therefore, the statement that cross-linking is a process in which undesirable bonds are formed in the presence of oxygen is true.

Eating large amounts of fruit and vegetables can indeed help unclog arteries and maintain normal blood pressure. Fruits and vegetables are rich in nutrients, including fiber, antioxidants, and vitamins, which promote heart health. The fiber in fruits and vegetables helps to reduce cholesterol levels and prevent the buildup of plaque in the arteries, thus keeping them clear. Additionally, the high potassium content in these foods helps to balance sodium levels in the body, which is essential for maintaining healthy blood pressure. Therefore, it is true that consuming ample amounts of fruits and vegetables can contribute to unclogging arteries and maintaining normal blood pressure.

Free radicals are highly unstable, reactive molecules. They are formed as a natural byproduct of various cellular processes and can cause damage to cells and tissues. They have an unpaired electron, which makes them highly reactive and capable of initiating chain reactions that can harm DNA, proteins, and lipids. Antioxidants help neutralize free radicals and prevent their harmful effects. Enzymes are biological catalysts that facilitate chemical reactions in the body. Nutrients are essential substances needed for growth, development, and maintenance of the body, but they are not specifically related to the stability or reactivity of molecules.

Catechins, which are antioxidants, are actually found in abundance in red wine, not white wine. They are primarily located in the skin of red grapes, not in the pulp. Therefore, the statement that catechins are only found in abundance in white wine and in the red grape skin is incorrect.

The statement suggests that there is a difference between the cells in a wrinkle and the cells from the face's smooth areas. However, this statement is false. There is no inherent difference in the cells themselves between a wrinkle and a smooth area of the face. Wrinkles are formed due to a combination of factors such as aging, sun damage, and loss of collagen and elastin in the skin. The cells in both areas are the same, but the structure and arrangement of the cells may differ, leading to the appearance of wrinkles.

Eating a diet that includes a high percentage of raw food, specifically 80%, can help to avoid leucocytosis. Leucocytosis is a condition characterized by an increase in the number of white blood cells in the body, which can indicate an immune response or infection. Raw food, such as fruits, vegetables, and nuts, are rich in nutrients and enzymes that support a healthy immune system. By incorporating a significant amount of raw food into each meal, the body can better maintain a balanced immune response and reduce the risk of leucocytosis.

Antioxidants are indeed bioflavonoids that can help boost the immune system and protect against certain diseases. However, the statement incorrectly states that antioxidants specifically build up resistance to colds, flu, and chest infections. While antioxidants can support overall immune health, they are not the sole factor in preventing or treating these specific illnesses. Therefore, the correct answer is False.

Alcohol should not be consumed by pregnant women as it can harm the developing fetus. It should also be avoided if someone is taking medication, as alcohol can interact with certain drugs and cause adverse effects. Additionally, individuals who are recovering alcoholics should abstain from drinking to maintain their sobriety and prevent relapse. The statement "Under 16 years of age" does not provide a valid reason for not consuming alcohol, so it is not one of the correct answers.
