1. Which of the following structures is responsible for filtering blood in the kidneys?

Correct answer: B

Rationale: The correct answer is B: Glomerulus. The glomerulus, located in the nephron of the kidney, is a network of tiny blood vessels responsible for filtering blood. It removes waste products and excess substances to form urine. The ureter carries urine from the kidneys to the bladder and is not involved in blood filtration. The nephron is the functional unit of the kidney where blood is filtered and urine is produced. The renal artery supplies blood to the kidneys but is not directly involved in the filtration process.

2. A consumer makes a $400 down payment on a television that costs $1,570. Which of the following is the number of months it will take to pay off the television with monthly payments of $100?

Correct answer: A

Rationale: After the $400 down payment, the remaining balance is $1,170. With monthly payments of $100, it will take 12 months to pay off the remaining balance. Therefore, the correct answer is 12 months. Choice B (16) is incorrect as it exceeds the required timeframe. Choice C (15) is incorrect as it is close but still one month over the correct timeframe. Choice D (11) is incorrect as it underestimates the time needed to pay off the remaining balance.

3. What cellular process ensures the accurate transmission of genetic material during cell division?

Correct answer: A

Rationale: Mitosis is the correct answer. Mitosis is the process by which somatic cells divide to produce two identical daughter cells. During mitosis, the genetic material is accurately replicated and distributed to ensure each daughter cell receives a complete set of chromosomes. This process is crucial for growth, repair, and maintenance of multicellular organisms. Meiosis, on the other hand, is the type of cell division that occurs in germ cells to produce gametes (sperm and egg cells), focusing on genetic diversity through recombination and reduction of chromosome number. Replication is the process of copying DNA to produce an identical copy, essential for cell division but not the specific process ensuring accurate genetic material transmission. Transcription involves copying DNA into RNA, crucial for gene expression but not directly related to the accurate transmission of genetic material during cell division.

4. On a highway map, the scale indicates that 1 inch represents 45 miles. If the distance on the map is 3.2 inches, how far is the actual distance in miles?

Correct answer: A

Rationale: To find the actual distance in miles, you need to set up a proportion using the scale provided (1 inch = 45 miles). Since the distance on the map is 3.2 inches, you can set up the proportion: 1 inch / 45 miles = 3.2 inches / x miles. Cross-multiply to solve for x: 1 * x = 45 * 3.2, x = 144. Therefore, the actual distance in miles is 144. Choices B, C, and D are incorrect because they do not accurately calculate the actual distance using the scale provided.

5. Which of the following systems is responsible for transporting blood throughout the body?

Correct answer: B

Rationale: The correct answer is B: Circulatory. The circulatory system, made up of the heart, blood vessels, and blood, is responsible for transporting blood throughout the body. It plays a vital role in delivering oxygen, nutrients, hormones, and removing waste products from cells. The respiratory system, on the other hand, is responsible for gas exchange in the lungs. The nervous system transmits signals between different parts of the body, while the digestive system processes food and absorbs nutrients from it. Therefore, choices A, C, and D are incorrect as they are not primarily involved in the transportation of blood throughout the body.
