Answer:
Genetic recombination occurs due to crossing over between homologous chromosomes.
Explanation:
The evidence that best supports conversation during photosynthesis is: Light energy is converted to chemical energy during photosynthesis ( A )
Photosynthesis is the process whereby plants make use of water and carbon dioxide found in the atmosphere to transform/convert the light energy from the sun into chemical energy.in the process of synthesizing food
The products of photosynthesis include oxygen and glucose while the conversion during photosynthesis takes place when the chloroplast absorbs the light energy from the sunlight and converts it another form of energy ( chemical energy ).
Hence we can conclude that The evidence that best supports conversation during photosynthesis is ; Light energy is converted to chemical energy during photosynthesis.

Once you finish
growing to adulthood, neurons stop dividing. Hair follicle cells constantly
divide throughout your lifetime since they are constantly producing cells that
become part of the hair itself as they die. So in an adult, the rate of cell
division for neurons is zero (although there is some counter-evidence but it is
certainly very low) while the hair follicle rate is much higher on the order of
once every few days or faster.
Answer:
Explanation:
1. Topoisomerase is an enzyme helps in over winding Or underwinding of DNA during replication. Helps in the topological correction. So non-functional topoisomerase leads to tangled DNA and prevents replication..
2. Primases are the enzymes helps in the synthesis of short RNA sequences used as primers in replication. Non functional primase leads to no primer synthesis.
3. DNA Polymerase is an enzyme helps in the addition of new nucleotide to the growing strand in replication. Non functional DNA polymerase prevents the strand growing as no new nucleotides were added.
4. Helicases are the enzymes helps in the separation of double strands into single and helps in each strand to be copied. Non functional helicase leads to prevention of unwinding of strands and replication inhibition.
5. ligase is an enzyme that joins nicks(small gaps) in the DNA strand by creating ester bond. Non functional ligase leads to unjointed gaps of lagging strand.
6. Single strand binding proteins(SSB's) are the small proteins that binds to the single strands of DNA and holds them in a place not to get together while replicating. Non functional SSB's leads to parental strands come back together and prevents replication.
