2. In polar regions, phytoplankton.

natka813 [3]

Answer:

b. thrive during the summer, when sunlight increases

Explanation:

Phytoplankton production is highly associated with latitude and season. In polar regions, phytoplankton production is reduced to the summer (and eventually spring) season. In consequence, the zooplankton that eats phytoplankton only can survive during the spring and summer seasons. On the other hand, in tropical areas, there exists a nearly constant phytoplankton production all year round.

What additional characteristic (x) belongs in the central section of the above venn diagram? F. Ribosome G. Mitochondria H. Chlo

Maru [420]

Explanation:

<u>F. Ribosome</u>

Around the endoplasmic reticulum, proteins are transported. The Endoplasmic Reticulum is a cytoplasmic membrane network. This continuous method not only raises the surface area within the cell but also conducts protein folding, synthesis, and transport.

Further Explanation:

Free ribosomes synthesize most proteins that operate in the cytosol (such as actin) or nucleus (such as DNA polymerase). Proteins that act within the endomembrane system (such as lysosomal enzymes) or those that are intended for cell secretion (such as insulin) are synthesized in the rough endoplasmic reticulum ER by bonded ribosomEs.

The rest of the ER that doesn't include ribosomes is called the smooth ER, and may contain lipids, enzymes, and other proteins. The first amino acids in the that polypeptide chain serve as a signal sequence as a protein bound for the endomembrane system is being synthesized by a ribosome. The signal sequence ensures that the ribosome binds to the ER's outer membrane and the protein gets into the ER lumen.
