The light reactions take place in the _________ and the Calvin cycle takes place in the _________.
stroma; thylakoids
thylakoids; stroma
inner membrane; outer membrane
chloroplasts; mitochondria
mitochondria; chloroplasts
thylakoids; stroma
Within the chloroplast, the light reactions take place in the flattened sacs called thylakoids and the Calvin cycle takes place in the thick fluid called the stroma.
Hope this helps.

Some of the question I will ask about the lionfish include;
(i) What is the growth rate of lionfish number?
(ii) What range of salinities that lionfish can tolerate?
(iii) How do fish affect the first productivity of the coral reef?
(iv) How are lionfish affecting other species in the coral reef?
(v) How will the climate-ocean acidification and climate changen can affect the behaviour of lionfish?
The correct question with the options would be:
During which part of the cell cycle is DNA polymerase most active?
a. G1 phase of interphase
b. mitosis
c. S phase of interphase
d. G2 phase of interphase
e. cytokinesis
The correct answer is c. S phase of interphase.
The replication of the entire genome or the whole DNA occurs during the S-phase or also called synthesis phase. Therefore, the enzyme is DNA polymerase which carries out the replication of DNA shows its maximum activity. The DNA polymerase is active in various cell cycle checkpoints to detect the DNA damage but the repair action of DNA polymerase involves only a small region of DNA as compared to the whole genome during the S-phase.
During its T-Tauri phase, when the Sun first started shining, it was not very bright. But it was very powerful, nevertheless, and spit out a stream of <span>particles into space.</span>
