<h2>Answer:</h2>
The correct sequence of organelles involved in making and packaging of proteins is option C: ribosomes, endoplasmic reticulum, and Golgi complex.
<h3>Explanation:</h3>
- The protein synthesis which is the translation of mRNA is done on <u>ribosomes.</u>
- As the protein is produced then it goes for modification in the <u>endoplasmic reticulum.</u>
- After some modifications proteins are packed into vesicles for the intercellular and intracellular transport.
- This packing is done in <u>Golgi apparatus.</u>
Answer:
Hydrophillic head and a hydrophobic tail
Explanation:
Every fatty acid is composed of long chain of hydrocarbon tail. This hydrocarbon tail is nonpolar and insoluble in water. Hence this tail is labeled 'hydrophobic'.
However, the head of the fatty acid contains polar COOH group which is capable of interacting with water, hence the head is hydrophillic.
Hence, a fatty acid is composed of a hydrophillic head and a hydrophobic tail.
