Instructions Question 1 1 out of 1 points What function does the nucleolus have? Answer Selected Answer: codes for the synthesis of ribosomal RNA Correct Answer: codes for the synthesis of ribosomal RNA Response Feedback: The nucleolus produces ribosomal RNA (rRNA) which will be sent out of the nucleus into the cytoplasm.
Question 2 1 out of 1 points Without a centrosome, cells would not be able to Answer Selected Answer: move organelles around the cytoplasm. Correct Answer: move organelles around the cytoplasm. Response Feedback: The centrosome lies outside the nucleus and serves as an organizing center for microtubule formation. Microtubules radiating from the centrosome act as tracks along which organelles and other materials can move. Question 3 1 out of 1 points What does the folding of the mitochondrial inner membrane shown here provide? Answer Selected Answer: greater surface area for ATP production Correct Answer: greater surface area for ATP production Response Feedback: The inner membrane of a mitochondria is highly convoluted into folds called cristae. These cristae increase the surface area of the inner membrane to maximize the contact of enzymes needed in the process of cellular respiration. Question 4 1 out of 1 points Disease-causing bacteria often attach to cells they attack. The bacterial structures used to aid that attachment are ________. Answer
Selected Answer: fimbriae Correct Answer: fimbriae Response Feedback: The fimbriae are small bristle-like fibers that from the cell surface. They help bacteria attach to a surface. Question 5 1 out of 1 points Which of the following human cells would contain cilia? Answer Selected Answer: cell from the trachea (windpipe) Correct Answer: cell from the trachea (windpipe) Response Feedback: The trachea have need for ciliated cells that aid in keeping the passage way clear of debris and reducing risk of unwanted materials going deeper into the respiratory pathway.
