Which of the following is the structure through which blood exits the glomerulus?

A. Proximal tubule

B. Distal tubule

C. Afferent arteriole

D. Efferent arteriole

Answer Explanation:

The glomerulus is a network of capillaries that filters blood and forms the primary urine. The blood enters the glomerulus through the afferent arteriole and leaves through the efferent arteriole. The efferent arteriole has a smaller diameter than the afferent arteriole, creating a high pressure in the glomerulus that facilitates filtration.

Therefore, the Correct Answer is D.

Q #1: Which of the following organic molecules contain both an amine and carboxyl group?

A. Lipids

B. Proteins

C. Chitin

D. Cellulose

Answer Explanation

An amine group is a nitrogen atom bonded to three hydrogen atoms, and a carboxyl group is a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group. These groups are important for the formation of amino acids, which are the building blocks of proteins.
Q #2: Which of the following is the main function of centrosomes in animal cells?

A. Organelle trafficking

B. Pathogen digestion

C. Microtubule organization

D. Cytoplasm formation

Answer Explanation

Centrosomes are small structures that are found near the nucleus of animal cells. They consist of two centrioles that are surrounded by a protein matrix called the pericentriolar material. The main function of centrosomes is to organize the microtubules, which are long, hollow tubes that form part of the cytoskeleton. Microtubules are involved in many cellular processes, such as cell division, cell movement, and intracellular transport. Centrosomes act as the main microtubule-organizing centers (MTOCs) in animal cells, meaning that they nucleate and anchor the microtubules
Q #3: Which of the following statements best supports the hypothesis that viruses can cause cancer?

A. Cellular DNA has sequences related to viral sequences.

B. Cancerous and normal cells share genetic sequences.

C. Viruses and cancer cells both replicate rapidly.

D. Genes that regulate cell division are found in some viruses.

Answer Explanation

Viruses can cause cancer by inserting their genetic material into the host cell's DNA, disrupting the normal regulation of cell division and growth. This process is called viral oncogenesis. Some viruses, such as human papillomavirus (HPV) and hepatitis B virus (HBV), are known to cause certain types of cancer in humans. Genes that regulate cell division are found in some viruses. This statement implies that some viruses have the ability to alter the host cell's genes and induce cancerous changes.
