Question

(i).Variation : Inheritance : : ______ : Sudden Change
(ii) Ozone depletion : CFC : : ______ : SO2
(iii) Cytokinesis : Division of cytoplasm : : ______ : Nuclear Division

(iv) Grana : Light Reaction : : ______ : Dark Reaction

(v) Adenine : Thymine : : ______ : Guanine.​

Answer 1

Answer: hope it helps

Explanation :

Answer 2

The blanks have been filled according to the conditions as follows:

(i).Variation : Inheritance : : mutation : Sudden Change

(ii) Ozone depletion : CFC : : Acid rain  : SO2

(iii) Cytokinesis : Division of cytoplasm : : Karyokinesis  : Nuclear Division

(iv) Grana : Light Reaction : : Stroma : Dark Reaction

(v) Adenine : Thymine : : Cytosine : Guanine.​

1. Variation is caused due to inheritance and sudden change is due to mutation.

2. Ozone depletion is caused by CFC and Acid rain is caused by SO2.

3. Cytokinesis is a process during which cytoplasm divides while karyokinesis involves division of nucleus.

4. The site for light reaction is grana and dark reaction is stroma in photosynthesis.

5. Nucleotide bases pairing- Adenine pairs with Thymine while Cytosine pairs with Guanine.
