Can't see the chart. But chloroplasts, cell wall, central vacuole are only in plant cells
Answer:
A cocoon is a protective casing that protects and shelters the silkworm while its transitioning from predators and other threats. Within the cocoon the silkworm transitions into a pupa, the pups is the stage between the larvae and adult moth. After two weeks the pupa finishes it's transition into a moth.
B is correct the births exceed deaths
Answer:
We see more of the lighted side of the moon because it is growing, so we see more
The time it takes to go from new moon to full moon is 2 weeks, because it takes a whole month (4 weeks) to go from new moon to full moon to new moon
P.S. PLEASE give me Brainliest?
Answer: All of the statements are true.
Explanation:
Purines are biologically synthesized as nucleotides and in particular as ribotides, that is, bases attached to ribose 5-phosphate. Adenine and guanine are both derived from the nucleotide inosine monophosphate (IMP), which is the first compound in the pathway to have a completely formed purine ring system.
Purine nucleotides can be synthesized in two distinct pathways. First, purines are synthesized de novo, starting with simple starting materials such as amino acids and bicarbonate. the purine bases are assembled already attached to the ribose ring. Alternatively, purine bases, released by the hydrolytic degradation of nucleic acids and nucleotides, can be salvaged and recycled. Purine salvage pathways are mostly noted for the energy that they save and the remarkable effects of their absence.
All statements are correct because the organization of purine synthetic enzymes involves multifunctional enzymes, reversible enzyme formations, through out the sequence there is maintenance of high local concentration and the ten steps requires only six enzymes.
