Answer:
B
Explanation:
Photosynthesis and cellular respiration are opposite processes, so a reactant of one would be the product of the other and vice versa. This means that A, C, and D are false because they don't apply to both processes. B is true because photosynthesis requires chloroplasts and cellular respiration requires mitochondria to occur.
Yes. It is common for a normal, healthy individual to carry potentially pathogenic organisms in their upper respiratory tract.
The human upper respiratory tract serves as a reservoir for a diverse community of commensals and potential pathogens, such as Haemophilus influenzae, Moraxella catarrhalis,etc. which can occasionally develop into pathogens and cause infectious diseases. Viruses are responsible for the majority of upper respiratory tract infections.
Nasal hairs are used to catch debris. Particles are propelled upward and out of the respiratory tract by cilia on the epithelium of the trachea and bronchi. The respiratory system has a feature that guards against infections.
Therefore, It is common for a normal, healthy individual to carry potentially pathogenic organisms in their upper respiratory tract.

Protista are eukaryotic organisms that are neither plants, animals or fungi. They do not have a natural group with whom they share common ancestor. They have a unique features that set them apart from the rest of the kingdom which are unicellular and microscopic.
