True. A protein becomes functional only when it reaches its tertiary shape (3D). It is not necessary for the protein to reach the quaternary stage, but that is just a more complex functioning protein. It really is just two tertiary merged together. Example is red blood cells.
Answer: B. Water breaks down into oxygen molecules for respiration.
Water is the required for photosynthesis, a process by which plants (terrestrial and aquatic) makes their food by utilizing water as a reactant to produce oxygen and glucose as product. The glucose act as a source of energy for conducting various metabolic processes in plants but oxygen is released in the air.

This oxygen is necessary for terrestrial and aquatic animals for respiration. Therefore, water breaks down into oxygen by the process of photosynthesis, hence water plays important role in respiration in living beings.
<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>
I think the correct answer from the choices listed above is the third option. The term that describes all of the non-living components of an ecosystem would be abiotic. Abiotic<span> components or </span>abiotic<span> factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.</span>
