Explanation:
Bacteria is a unicellular organism don't have any nucleus or cell walls and reproduce by splitting in two.
2. Paramecium is also a unicellular organism that reproduces by splitting in two.

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
<u>Answer:</u>
Ecosystem is the level of organization which includes a community, population, and an individual.
<u>Explanation:</u>
- An ecosystem is the dynamic system of biotic and abiotic components that helps to maintain the circle of life.
- In an ecosystem there are different species and population of those species that exist together within a physical environment that is composed up of soil, water, minerals as well as weather conditions and climates.
- In ecosystem, there is the food chain as well as food web. The change in any component of the biotic or abiotic component would bring about change in every other component. Each component is interrelated with one another in an ecosystem.
It has to be C.
1 is photosynthesis.
2 is fermentation in yeast (alcohol right there)
