Answer:
a) Carbon fixation phase
b) stroma
c) Ribulose bisphosphate (RuBP)
d) 5-carbon molecule
e) two carbon molecules
f) glycerate-3-phosphate (GP)
Explanation:
In the Calvin cycle (also named C3 cycle or Calvin-Benson cycle), the CO2 is reduced in a cyclic process, where the first stable reaction product is 3-phosphoglyceric acid (3-PGA), a 3-C molecule, and the CO2 acceptor molecule is Ribulose bisphosphate (i.e., Ribulose 1, 5-diphosphate). The CO2 enters the chloroplast by passing through the stomata and diffusing into the stroma of the chloroplast, which is the site where sugar is synthesized. The Rubisco enzyme or RuBP carboxylase catalyzes the first step of the cycle (i.e., the attachment of CO2 to RuBP). The result of this reaction is an unstable 6C molecule, which breaks down into two 3C molecules named glycerate-3-phosphate (GP).
c because fungi are.prokaryotic heterotrophes
Sponge larvae posses cillia with unusual terminal expansions which are curled or biconcave in shape externally, as seen by scanning electron microscopy. Thin sections, passing through the point where the ciliary shaft enters the expanded area reveal the ciliary axoneme to be surrounded by many membranous folds, some of which are vesicular. The 'club footed' cilia occur in disparate groups of Demospongiae and most frequently, all larval cilia are of this type. There is no immediately obvious correlation between the type of movement displayed by the larvae and the occurrence of terminally expanded cilia.
Answer:
This experiment proved that DNA replicated semiconservatively; half the original polynucleotide is conserved in each of the two copies
Explanation:
Semi-conservative mode of replication means that the two strands of DNA unwind from each other, and each of themacts as a template for synthesis of a new, complementary strand. As a result, two formed DNA moleculesc ontain one original strand and one new strand.
Meselson and Stahl experiment showed this model by labeling the DNA of bacteria across generations using isotopes of nitrogen ( patterns of DNA labeling showed the mode of replication).
Answer:
we do it to select the best seeds
the seeds floating on the top are bad seeds which are empty inside
the seeds that are on the bottom are good seeds they are heavy
