E) Chromosomes move to the middle of the cell. to 13) 13) In photosynthesis, redox reactions ultimately transfer electrons from A) C6H1206.02 B) H20... C6H1206 D) CO2...02 E) H2O... CO2

Explanation / Answer

7) the correct option is option (d) DNA and Protein it is a thread like structure in which the DNA is packed with histone protein..

8) the correct option is option (c) one old strands and one new as the replication are semi-conservative in nature..

9) the correct option is option (c) all the peas are yellow hence the yellow is dominant over the green trait..

10) the correct option is option (a) chrmoschro duplicate where the cell preapre for the next round of cell division..

11) the correct option is option (c) CAGGTA as it DNA hence it contains T..

12) the correct option is option (a) crossing over the sister chromatids called synapses
