Sure, I'd be happy to provide feedback on your answers! Here are the correct answers for each question, along with some explanations:
1- The process of breaking a complex substance down into smaller components is called?
Correct Answer: D- catabolism
Explanation: Catabolism is the process of breaking down complex substances into smaller components. It is the opposite of anabolism, which is the process of building up complex substances from smaller components.
2- An approach to skin cancer treatment would involve surgery, either alone or combined with?
Correct Answer: A- chemotherapy
Explanation: Surgery is a common treatment for skin cancer, but it is often combined with chemotherapy for more effective treatment. Chemotherapy involves the use of drugs to kill cancer cells.
3- Which one of the following compounds is an organic molecule?
Correct Answer: B- Hair and nails
Explanation: Organic molecules contain carbon and are typically found in living organisms. Hair and nails are composed of keratin, which is an organic molecule.
4- Where are keratinized cells found in the body?
Correct Answer: B- hair and nails
Explanation: Keratinized cells are found in structures such as hair and nails. These cells are dead and filled with keratin, a protein that provides strength and protection.
5- What are the constituents of DNA?
Correct Answer: B- Sugars, phosphates, and nitrogenous bases
Explanation: DNA is composed of nucleotides, which consist of a sugar (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine).
6- Structurally, what is the difference between the dermis and the epidermis?
Correct Answer: B- the dermis contains more types of tissue
Explanation: The dermis is located beneath the epidermis and is composed of various types of tissues, including connective tissue, blood vessels, and nerve endings. The epidermis, on the other hand, is the outermost layer of the skin and is primarily made up of epithelial cells.
7- Normal urine is _________, as indicated by its pH value?
Correct Answer: C- slightly acidic
Explanation: Normal urine has a slightly acidic pH, typically ranging from 5.5 to 6.5. This acidity helps prevent the growth of bacteria in the urinary tract.
8- A dog bites a large chunk of flesh from a man's leg. The large, open wound will likely heal by the process of?
Correct Answer: D- secondary graft
Explanation: A large open wound, such as a dog bite, is likely to heal by secondary intention or secondary graft, which involves the healing of the wound from the bottom up. This process often results in the formation of granulation tissue.
