The process in which foods you eat are broken down and absorbed is called
- A.
Metabolism
- B.
Digestion
- C.
Respiration
Correct Answer
B. DigestionExplanation
Digestion is the correct answer because it refers to the process in which the foods we eat are broken down and absorbed by our body. During digestion, the food is broken down into smaller molecules by mechanical and chemical processes in the mouth, stomach, and small intestine. These smaller molecules are then absorbed into the bloodstream and used by the body for energy, growth, and repair. Metabolism and respiration are related processes but do not specifically encompass the breakdown and absorption of food.Rate this question:

The most common form of skin cancer is
- A.
Carcinoma
- B.
Melanoma
- C.
Sarcoma
Correct Answer
A. CarcinomaExplanation
The most common form of skin cancer is carcinoma. Carcinoma refers to cancer that originates in the epithelial cells, which are the cells that line the outer and inner surfaces of the body. Skin carcinoma typically develops in the top layer of the skin and is often caused by long-term exposure to the sun's ultraviolet (UV) rays. It is important to detect and treat carcinoma early as it can spread to other parts of the body if left untreated. Melanoma, on the other hand, is a less common but more aggressive form of skin cancer that develops in the melanocytes, the cells that produce pigment in the skin. Sarcoma is a type of cancer that develops in the connective tissues, such as bones, muscles, and blood vessels, and is not commonly associated with skin cancer.Rate this question:
