Question

please answer this question
biology (35 - 40)​

Answer 1

Answer:

36 - diffusion

37- raisin will shrink due to exosmosis

38- isotonic

39- it occurs in plants is wrong as it occurs in animals as well.

40- 30% ( final wt- initial wt / initial wt *100)

Answer 2

Answer:

(36) The process helps in movement of carbon dioxide or oxygen across the cell membrane is called as (d) Diffusion .

(37) If we will place raisins in sugar solution then the water potential of solution is low and water potential inside raisins is high. Therefore, water will move from High water potential to low water potential and hence, water will move from raisins to solution and raisins will get shrink. Hence, option B) Raisins shrink is the correct option.

(38) Concentration of solution is same as concentration inside cell is called as (B) Isotonic Solution.

(39) The following statement is incorrect about osmosis

(a) It occurs only in plants.

(40)

• Initial weight = 10 g
• Final weight = 13 g

=> Mass % = (Final weight - Initial weight)/ Initial weight × 100

=> Mass % = (13-10)/10 × 100

=> Mass % = 3/10 × 100

=> Mass % = 3 × 10

=> Mass % = 30%

Option (C) 30%.
