Passive Transport: Simple Diffusion. Diffusion across a cell membrane is a type of passive transport, or transport across the cell membrane that does not require energy. ... Molecules that are hydrophobic, just like the hydrophobic region, can pass through the cell membrane by simple diffusion.
Answer:
The correct answer will be option-D.
Explanation:
In eukaryotes, the process of transcription takes place inside the nucleus whereas translation takes place in the cytosol. So, mRNA has to export to the cytosol from the nucleus.
Before export, the post-transcriptional modification takes place like 5' capping, 3' tailing and splicing mechanism.
The capping is done at 5' end by adding modified guanine (G) nucleotide which protects the mRNA from exonuclease activity and tailing is done at 3' end by adding adenine nucleotides which provides stability to the mRNA.Splicing removes the junk DNA called introns and joins the exons before export.
Thus, option-D is the correct answer.
The algae in the ocean have a very high Net Primary Productivity (NPP) and a very low amount of store biomass. This is because THE GROWTH RATE OF ALGAE IN THE OCEAN IS HIGH. The store biomass is low because THE PRIMARY CONSUMERS FEED ON THESE ALGAE THUS LOWERING THE BIOMASS AMOUNT. The production of biomass is related to the NPP.
Answer:
D
Explanation:
A stomata is responsible for opening up, to allow gas exchange which is needed for photosynthesis .
