Great job narrowing down your answer choices! Let's go through each question and explain how to determine the correct answer.
1. For the first question, you eliminated option D, which is a good start. Now, let's review the remaining options. Option A states that nerves are made of sensory and/or motor fibers, which is correct. Option B states that sensory nerves are efferent nerves, but this is not correct. To determine if it is correct or not, you need to understand the concepts of efferent and afferent nerves. Efferent nerves carry signals from the central nervous system to the muscles or glands, while afferent nerves carry signals from sensory organs to the central nervous system. Since sensory nerves are a type of afferent nerves, option B is incorrect. Therefore, the answer is B.
2. The question asks about the definition of blood serum. Option D states that blood serum is plasma with a clotting factor removed. To determine if this is correct, you need to understand the concept of blood serum. Blood serum is the fluid remaining after the plasma is removed from whole blood. Option D aligns with this definition, so the answer is D.
3. The question is about Kaposi's sarcoma and its association with another infection. Option B states that a patient showing Kaposi's sarcoma is likely to be infected with HIV. To determine if this is correct, you need to consider the association between Kaposi's sarcoma and HIV. Kaposi's sarcoma is a type of cancer often seen in individuals with weakened immune systems, such as those with HIV/AIDS. Therefore, option B is correct, and the answer is B.
4. The question asks for the false statement about colds. Option C states that chicken soup and antibiotics work equally well as treatment for colds. To determine if this is correct or false, you need to consider the effectiveness of chicken soup and antibiotics in treating colds. Antibiotics are not effective against viral infections, which cause most colds. However, chicken soup may provide relief from symptoms. Therefore, option C is false, and the answer is C.
Overall, your answers were correct for all the questions. Great job! If you have any more questions, feel free to ask.
