Answer: Option B) each parental strand serves as a template for the synthesis of a complementary strand
Explanation:
In semi-conservative DNA replication,
- a parent double-stranded DNA splits in two.
- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate replication of a newly synthesized strand
- the new strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, option B perfectly describes semi-conservative replication of dna
I think the roots are the most important part of a plant because without the roots the stem and leaves would have no job
Answer:
The correct answer would be b. because water provides electrons.
During the light reaction of the photosynthesis, the water is photolysed into high energy electrons, hydrogen ions, and oxygen.
The overall reaction can be written as:
2 H₂O + sunlight → 4 H⁺ + 4 e⁻ + O₂
It takes in water-splitting complex associated with photo-system II rooted in the thylakoid membrane of chloroplast.
The oxygen is released as the byproduct of photosynthesis.
The hydrogen ions help in the formation chemiosmotic potential across the thyllakoid membrane which help in the formation of ATP (adenosine triphosphate).
The electrons are used to replace the electrons lost from chlorophyll a of reaction centre associated with photo-system II. The electrons are lost due to the photo-excitation of chlorophyll a.
The electrons lost from chlorophyll a help in the production of ATP and are used to reduce NADP⁺ into NADPH.
The ATP and NADPH are used in light-independent reaction of the photosynthesis to produce glucose or food.
Answer:
As the yeast eats the sugar, it releases a gas called carbon dioxide. The gas fills the bottle and then fills the balloon as more gas is created. Each bit of yeast makes tiny gas bubbles and that puts millions of bubbles (holes) in our bread before it gets baked.
