Answer:
The correct answer is-ER Golgi plasma membrane
Explanation:
Rough endoplasmic reticulum contains the ribosomes on it which helps in the formation of proteins from the mRNA by the translation process. The proteins chains synthesized are pushed in the cisternae of the RER where the primary modification of proteins takes place.
Then these proteins are released towards closely associated Golgi apparatus where the further modifications and processing of proteins takes place like glycosylation, sulfation, etc.
After the modification, the proteins are released from the Golgi in enclosed vesicles to their destination like they can be sorted in plasma membrane or lysosomes. So the correct answer is-ER > Golgi > plasma membrane.
Answer:a) a sturdy-finned, shallow-water lobe-fin whose appendages had skeletal supports similar to those of terrestrial vertebrates.
Explanation:
An ancestor - An earlier type of a species at any distant time — a progenitor.
A tetrapod is any vertebrate with four limbs. It includes any vertebrate (such as birds or snakes) that have evolved from early tetrapods — especially all members of the superclass Tetrapoda.
The presence of bones that support the appendages in Lobe – fin fish were found to be similar to the categorical skeletal supports found in the limbs of sample tetrapods. The sub class crossopterygii includes the Lobe – fin fish, which is seen as one of the recent common ancestor of living tetrapod today.
