Answer:
3rd generation = 2 Hybrid DNA molecules + 6 Light DNA
In Percentage 2÷8 × 100 = 25%
25% of the DNA are hybrid
Explanation:
Semi conservative model proposed by Watson and Crick states that one strand of the DNA comes from parent DNA which act as a template for the other newly formed strand.
First generation:
If cells containing 15 N DNA are transferred to a medium with only 14 N then in initial first generation two parent strands becomes separated and act as template for newly synthesized strands. this means that in first generation both DNA molecules are hybrid, one strand of 15 N DNA and other strand of 14 N DNA
Ist generation = 2 Hybrid DNA molecules
Second generation:
In Second generation these two hybrid molecules become unzip. Two strands are 15N and two strands are 14N. All these 4 strands act as template and 4 new strands are synthesized. The molecules of Hybrid DNA is still 2 with 2 molecules of Light DNA.
2nd generation = 2 Hybrid DNA molecules + 2 Light DNA
Third generation:
In Third generation these two hybrid molecules and two light DNA molecules become unzip. Two strands are of 15N and six strands are of 14N. All these 8 strands act as template and 8 new strands are synthesized. The molecules of Hybrid DNA is still 2 with 6 molecules of Light DNA.
3rd generation = 2 Hybrid DNA molecules + 6 Light DNA
In Percentage 2÷8 × 100 = 25%
25% of the DNA are hybrid
No net primary production occurs BELOW THE OCEAN DEPTH WHERE LIGHT IS 1% OF SURFACE LIGHT.
Net primary production = <span>gross photosynthetic carbon fixation - the carbon respired to support maintenance requirements of the whole plant.
In short, net primary production is the "available" carbon left for to aid in plant growth and consumption of other heterotrophic organisms.</span>
<span>Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0 and 100%.</span>
3. The product should use the least sig figs of the two numbers.
Correct answer: C). Oxidative phosphorylation
Oxidative phosphorylation gives a basic unit of energy for all the metabolic processes called as ATP, it is a highly efficient metabolic process which is known to produce a large amount of ATP.
During the process of oxidative phosphorylation, electrons are exchanged between the molecules, that creates a chemical gradient, which is required for the production of ATP. It is known to produce more ATP called the energy currency of cell that any other cellular respiration. It produces 90% of the total ATP synthesized in the cell.
