The net primary productivity is usually more than 80% of gross primary productivity.
fomenos

Answer:

b. False

Explanation:

  • As GPP stands for the gross primary productivity, it's the total amount of energy produced in the process and the NPP is the net primary productivity. NPP is the difference between the GPP and the energy used by the producer for the process of respiration.
  • GPP is a continuous and ongoing process that consumes the energy as compared to the NPP that store energy and not being used. Thus, GPP can affect NPP but NPP does not affect GPP.
  • For example, GPP is completely being dependent on the chlorophyll content of the plant, but NPP is independent of that content of chlorophyll.

Oh, no... you dropped your study flashcards, and now they're out of order! Put them back into the correct order for a eukaryotic
ivanzaharov [21]

Answer:

The correct order would be:

b. "Unwind the DNA molecule near the promoter."

d. "Transcribe the complementary RNA strand."

c. "Exit the nucleus to the cytoplasm."

a. "Combine the mRNA strand with a ribosome and a tRNA carrying a methionine."

The given order is according to the central dogma of a cell. According to central dogma DNA is first transcribed into mRNA which is then moved out of nucleus (in eukaryotic cells).

For transcription, the DNA is unwind near the promoter region where transcription factors and RNA polymerase binds the template strand. It then make mRNA which is moved out of the nucleus.

The mRNA then is translated with the help of ribosome and tRNA. The start codon in mRNA usually codes for methionine due to which tRNA carrying methionine recognises the start codon and initiate the process of translation.
