Answer: polyunsaturated fatty acid residues
Explanation: Unsaturated fatty acids have a lower melting point so arctic animals have these fatty acids in their membranes.
Answer: Lettuce
Explanation:
Lettuce is a plant, therefore it makes its own food through photosynthesis. Since it does this, we call it a producer or an autotroph.
Answer:
The correct answer will be- Golgi apparatus
Explanation:
The proteins are synthesized in the ribosomes whether they are attached to the endoplasmic reticulum or free. These synthesized proteins enter the lumen of the endoplasmic reticulum where they get packaged to go to Golgi apparatus.
The Golgi apparatus is the site of post-translational modification of the secreted proteins like ubiquitination, acetylation, phosphorylation and many others.
Thus, the Golgi apparatus is the correct answer.
You may be referring to the cytoplasm here. That is the "filling" within the cell. But if you are looking for specific transport of proteins, the ER folds proteins and then transport vesicles move them to the Golgi.
