An anorexic person is someone who experiences a prolonged eating disorder, which leads to a loss of appetite. They often have a distorted body image and an intense fear of gaining weight, which drives them to restrict their food intake severely. This can result in extreme weight loss and a skinny figure. However, it is important to note that anorexia is not simply characterized by excess body fat or being skinny, but rather by the underlying psychological and behavioral patterns related to food and body image.

Beta blockers are a type of medication that can slow down the heart rate. They work by blocking the effects of adrenaline on the heart, which helps to reduce the heart rate and lower blood pressure. This can be beneficial for individuals with conditions such as high blood pressure, angina, or certain types of irregular heart rhythms. Beta blockers are commonly prescribed by doctors to help manage these conditions and can effectively slow down the heart rate.

The factors that can determine your weight include height, gender, muscle mass, and diet. Height plays a role in determining weight as taller individuals tend to weigh more than shorter individuals. Gender also plays a role as men generally have more muscle mass and higher metabolic rates, leading to higher weight. Muscle mass is a significant factor as muscles are denser than fat, so individuals with more muscle will weigh more. Finally, diet is crucial as the type and amount of food consumed directly impact weight gain or loss.

Anabolic steroids are synthetic substances that are designed to mimic the effects of testosterone, the male hormone. They are commonly used to enhance muscle growth and athletic performance. By imitating testosterone, anabolic steroids can increase protein synthesis in cells, leading to muscle growth and improved strength. Therefore, it is true that anabolic steroids mimic the male hormone testosterone.

A sumo wrestler would most likely be classified as an endomorph. Endomorphs tend to have a higher percentage of body fat and a rounder, softer body shape. Sumo wrestlers typically have a large, heavy build with a significant amount of body fat, which is advantageous for their sport. This body type allows them to have the necessary strength and weight to compete effectively in sumo wrestling.

Diuretics are medications that increase urine production and promote the excretion of excess fluids and salts from the body. This helps to reduce fluid retention and lower blood pressure. By increasing the frequency of urination, diuretics help to eliminate excess water from the body, making you go to the toilet more often.

Boxing requires athletes to compete in specific weight classes, which means they need to maintain a certain weight to be eligible for their chosen class. In order to meet these weight requirements, boxers often need to lose weight through strict dieting and intense training. This is done to ensure that they are physically fit and have the necessary strength and agility to perform well in their matches.

The correct answer is "because you got told to." This suggests that the person is taking the quiz because someone instructed them to do so. It implies that they may not have chosen to take the quiz voluntarily, but rather out of obligation or following someone else's instructions.

The term "overfat" refers to having an excessive amount of body fat, which can be detrimental to one's health. This condition is different from being "overweight," which refers to having a higher body weight than what is considered healthy for a given height. "Anorexic" is a term associated with an eating disorder characterized by an extreme fear of gaining weight and self-starvation, which is not directly related to having excess fat. Therefore, the correct answer is "overfat."

Peptide hormones are known to play a crucial role in promoting muscle growth. They stimulate protein synthesis, enhance muscle cell repair and regeneration, and increase muscle mass. Therefore, it is true that peptide hormones help to increase muscle growth.

Erythropoietin is a hormone that stimulates the production of red blood cells in the bone marrow. It is commonly used to treat people with anemia, a condition characterized by a deficiency of red blood cells or hemoglobin in the blood. By increasing the production of red blood cells, erythropoietin helps to improve oxygen delivery to the body's tissues and alleviate symptoms of anemia such as fatigue and weakness. Therefore, the statement that erythropoietin is used to treat people with anemia is true.

There are multiple factors that can affect a person's weight. These include genetic factors, diet and nutrition, physical activity levels, and overall lifestyle choices. Each of these factors can have a significant impact on an individual's weight.
