Porque los parásitos no requieren tejido nervioso o muscular complejo?

Answers

Answer 1

Answer:

Hey mate.....

Explanation:

This is ur answer.....

Poorly developed nervous and muscular systems – because parasites live inside their hosts, they don't need eyes, ears or a keen sense of smell to detect potential predators nor a brain to facilitate escape. They have little need for a muscular system because they have no place to go.

Smooth endoplasmic reticulum has ribosomes attached to

Rough endoplasmic reticulum has ribosomes attached to its

Answers

The smooth endoplasmic reticulum is different from rough endoplasmic reticulum as the rough endoplasmic reticulum has ribosomes attached to its surface which are absent in smooth endoplasmic reticulum. Thus, the correct option is C.

What is Endoplasmic reticulum?

Endoplasmic reticulum (ER) is a large, dynamic structure which serves for many roles in the cell. There are two types of ER which are Smooth Endoplasmic Reticulum (SER) and Rough Endoplasmic Reticulum (RER). The diverse functions of the ER are performed by distinct domains present in the ER consisting of tubules, sheets and the nuclear envelope.

Rough endoplasmic reticulum contains ribosomes on its surface and synthesizes protein, whereas the smooth endoplasmic reticulum does not contain ribosomes and functions to make lipids and detoxify the cell. Large amounts of SER are found in the cells which participate in lipid metabolism and detoxification of the body, such as liver cells.

Therefore, the correct option is C.
