I mean, the basic answer would be the leaf of the cell. If you need to get more in depth than that, the palisade mesophyll layer of the leaf is where the majority of photosynthesis occurs.
The correct answer as to how heat is involved in photosynthesis and respiration would be that it is not needed. In other words, heat is not involved in photosynthesis and respiration.
- Heat stress actually limits photosynthesis because the functions of relevant enzymes is impacted.
- Heat is not required as input in respiration, but is generated as one of its products. Approximately 60% of the ATP generated during respiration is converted to heat.
Hence, when we are talking about involvement, heat is not involved in both photosynthesis and respiration but only generated as a product in the latter.

Answer: Option D) 8 segments, with the 2 original strands on different segments
Explanation:
During polymerase chain reaction, a double stranded DNA (dsDNA) is selectively and repeatedly copied in the PCR machine.
In the first round, the single piece of double stranded DNA (dsDNA) unwinds in two seperate strands, before complementary nucleotides are synthesized to establish double helix.
In the second round, the two dsDNA yields 4 segments before complementary nucleotides are synthesized to establish double helix.
In the third round, the four dsDNA yields 8 segments before complementary nucleotides are synthesized to establish double helix.
Thus, after 3 rounds, the two original strands are on the 8 different segments of copied DNA.
Each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.
