The leaves of a plant were covered with aluminium foil, how would it affect the physiology of the plant? OR How is lymph an important fluid involved in transportation? If lymphatic vessels get blocked, how would it affect the human body? Elaborate. Rohit wants to have an erect image of an object using a converging mirror of focal length 40 cm. (a) Specify the range of distance where the object can be placed in front of the mirror. Justify. (b) Draw a ray diagram to show image formation in this case. (c) State one use of the mirror based on the above kind of image formation. (a) A lens of focal length 5 cm is being used by Debashree in the laboratory as a magnifying glass. Her least distance c f distinct vision is 25 cm. Views: 5,316 CO 2 ​ and water move in and out of the cell? Discuss. ns. Substances like CO 2 ​ (which is cellular waste and requires to be excreted out by the cell) accumulates in high concentrations inside the cell. In the cell's external environment, the concentration of CO 2 ​ is low as compared to that inside the cell. As soon as there is a difference of concentration of CO 2 ​ inside and outside a cell, CO 2 ​ moves out of the cell, from a region of high concentration, to a region of low concentration outside the cell by the process of diffusion.
