ULJ, UL SECUIUS. Question Completion Status: QUESTION 1 Which of the following best describes a riboswitch? O A. The 5'UTR takes on secondary structure and prevents binding the ribosome O B. An antisense RNA that binds the 3'UTR and prevents translation. O C. 3'UTR structure of the mRNA becomes autocatalytic and cleaves the mRNA D. An miRNA binds the 5'UTR and prevents ribosome binding O E. A repressor protein that binds the operator and prevents transcription

Consider the correlation between heights of fathers and mothers and the heights of their sons. Refer to the accompanying technology output. Should the multiple regression equation be used for predicting the height of a son based on the height of his father and mother? Why or why not? Click the icon to view the technology output. Choose the correct answer below. O A. Yes, the multiple regression equation should be used for predicting the height of a son based on the height of his father and mother because the P-value in the ANOVA table is very low. B. No, the multiple regression equation should not be used for predicting the height of a son based on the height of his father and mother because the P-value for Intercept is not very low. O C. No, the multiple regression equation should be used for predicting the height of a son based only on the height of his father because the P-value for Father is smaller than the P-value for Mother. D. No, the multiple regression equation should not be used for predicting the height of a son based on the height of his father and mother because the R2 and adjusted R2 values are not very high.

. Metro by T-Mobile 8:56 AM 1 69% k Microscope Practice.pdf 6. The diagram below shows how a coverslip should be lowered onto some single-celled organisms during the preparation of a wet mount. 11. The diagram below represents a hydra as viewed with a compound light microscope. * If the hydra moves toward the right of the slide preparation, which diagram best represents what will be observed through the microscope? 1) 3) Why is this a preferred procedure? 1) The coverslip will prevent the slide from breaking. 2) The organisms will be more evenly distributed. 3) The possibility of breaking the coverslip is reduced. 4) The possibility of trapping air bubbles is reduced. 7. A cell in the field of view of a compound light microscope is shown in the diagram below. 2) 4) In which direction should the slide be moved to center this cell in the microscopic field? 1) to the right and up 3) to the left and up 2) to the right and down 4) to the left and down The diagram at the right represents a strand of algae viewed under the low-power objective of this microscope. Under the high-power objective, how would this same slide appear? 1) 3) 8. Which structure in a stained cheek cell would most likely be visible when viewed through the high-power objective of a compound light microscope? 1) cell wall 3) chloroplast 2) ribosome 4) nucleolus TUU 2) 4) 9.A wet-mount slide preparation of a specimen is stained in order to 1) eliminate some organelles 2) make cell structures more visible 3) use the high-power lens 4) remove water from the slid ☺ _10. A coverslip should be used for preparing a 1) frog for dissection 2) solution of iodine for food testing 3) wet mount of elodea (a simple plant) 4) test to determine the pH of a solution 13. A student views some cheek cells under low power, Before switching to high power, the student should 1) adjust the eyepiece 2) center the image being viewed 3) remove the slide from the stage 4) remove the coverslip
