I would say A and C. The circulatory system moves blood and nutrients similar to the plant moving water and nutrients. The endocrine system is responsible for hormones, glands and other such functions.
C6H12O6(s) + 9 O2(g)
-> 6 CO2(g) + 6 H2O(g)
There are 9 moles of O2 needed for the complete combustion of glucose.
Answer:
The pair will be:
- NH3/NH4⁺
- ClO⁻/HClO
Explanation:
A conjugate acid is formed after a base has reacted/accepted a proton.
Since H2O is amphiprotic, we can use it as the acid.
NH3 + H2O ⇄ NH4⁺ + OH⁻
ClO⁻ + H2O ⇄ HClO + OH⁻
after reacting, the base form conjugate acid.
