Phytoplankton; small cells that use photosynthesis to turn sunlight into food that live near the surface of the ocean. There also responsible for about half of the Earth's primary production. The seasons also affect how well there doing, they need the climate best for them to produce right, changing seasons doesn't nearly affect them as much as climate change though.
Hope this helps, have a BLESSED day! :-)

Answer:
a) into the ER
b) into the ER
c) into mitochondria
Explanation:
a) This signal is located at the N-terminus of the protein and acts before the internal signal is synthesized for import into the nucleus. When the protein enters the ER, the sequence of the import signal in the nucleus cannot work because the protein would be prevented from interacting with the cytosolic receptors.
b) The signal that is imported into the peroxisome cannot function once the protein was sequestered in the ER.
c) In order for the protein to be retained in the ER, the protein must first be imported into the ER. Without there being no signal for that import of the protein into the ER, that retention signal could not work.
