The statement 'polypeptides in the ER are usually larger than polypeptides synthesized from the same mRNA that have not entered the ER' is false.

The rough endoplasmic reticulum is the site where polypeptides enter so that protein formation can take place. Apart from protein formation, polypeptides are needed for various other metabolic functions by the ER.

Those polypeptides that are smaller in size can enter the endoplasmic reticulum because of the entering space and the small size of the endoplasmic reticulum. On the other hand, the polypeptides that are large, although being synthesized from the same mRNA, stay outside as they cannot enter the ER due to their large size.

Species that evolved in coral reef habitats always stay in those habitats. Coral reefs have much biodiversity, but most species

Anni [7]

Answer:

Most organisms that live in coral reef habitats are zooxanthellae.

Explanation:

zooxanthellae are the single-celled dinoflagellates that lives in mutual relationship with corals, jellyfish, and nudibranchs. These organisms have a mutualistic relationship between zooxanthellae and corals. Coral produces carbon dioxide and water in the process of cellular respiration while on the other hand, the zooxanthellae use this carbon dioxide and water to carry out photosynthesis for making their own food like plants so both the organisms get benefit from one another.
