<h2>Polychaetes </h2>

Explanation:

Polychaetes is any of the diverse, mostly marine segmented worms of the annelid class Polychaeta, characterized by having most segments with one pair of lateral, fleshy, lobe like appendages called parapodia, with numerous bristles projecting from them
Polychaetes have true segments and anterior to the true segments lie the prostomium and peristomium
This head region of two segments typically contains two pairs of eyes, three antennae, several tentacles, a pair of palps, and the mouth
Polychaeta is divided into Errantia and Sedentaria for convenience
Errantia (scaleworms, sea mice):A subclass of polychaete worms which have a large number of body segments, those of the head and posterior differing from the rest,the mouth often has several paired jaws
Most are vagile predators, others adopt a burrowing mode of life and are first recorded from the Cambrian
Sedentaria (bamboo worms, coneworms):A subclass of entirely marine worms in which the body segments and parapodia differ along the length of an individual,all Sedentaria are burrowers or tube-dwellers and are first recorded from the Ordovician

If the endoplasmic reticulum were removed from the cell, which organelle would not be able to function properly, and why? mitoch

marysya [2.9K]

Answer:

Golgi apparatus, because it packages proteins received from the ER

Explanation:

The function of the endoplasmic reticulum is to produce proteins. It can be smooth or rough. The rough endoplasmic reticulum has ribosomes, which make the proteins.

The Golgi apparatus receives proteins from the endoplasmic reticulum and modifies and sorts them. They are then concentrated and packed into vesicles which are released out of the cell membrane.

If the endoplasmic reticulum is removed, proteins cannot be made and the Golgi apparatus would not be able to perform its job.

Hope that helps.
