Answer:
Option C. The number of oxygen atoms is the same before and after the reaction.
Explanation:
When hydrogen combine with oxygen, water is formed. According to law of conservation of matter, matter cannot be created nor destroyed during a chemical reaction. So according to this law, the amount of reactants is equal to the amount of product produced after a chemical reaction and the number of oxygen atoms is the same before and after the reaction.
Answer:
Organisms that are more complex, such as eukaryotes, have cells that are specialized for specific functions. Gene regulation needs to be more complex to produce these specialized cells for complex organisms.

Answer:
sensor
Explanation:
Homeostasis refers to the ability of an organism to maintain the internal conditions of the body irrespective of the external conditions.
The homeostasis is maintained by the homeostatic mechanism which involves the 3 components which are the receptor or sensor, the integrating centre and the effector or organ.
In the given question, the peripheral chemoreceptors measures and sense the pH of the blood therefore the peripheral chemoreceptor will be considered as the "sensor component" of the homeostatic mechanism.
Thus, the sensor is the correct answer.
