Answer:
Explanation:Which of the following equations are balanced correctly?
2Ag2O → 4Ag + O2
Zn + HCl → ZnCl2 + H2
Cu + H2O → CuO + H2
2C4H10 + 13O2 → 8CO2 + 10H2O
They are essential for autotrophic processes, basically allowing plant life to thrive off of self-made nutrients/food
Answer:
Each organism absorbs minerals produced by the other
Explanation:
Lichen is a symbiotic association between fungi and alga. The fungus is able to absorb essential mineral ions like calcium, phosphate and potassium better than the alga thus benefiting the alga. The fungus in return gets organic materials from the alga. The alga provides organic nutrients for the lichen through photosynthesis and the lichen provides protection from drying out because the alga lives within the fungus's cell wall.
Answer:
Polar molecules occur when there is an electronegativity (a charge) difference between the bonded atoms. Nonpolar molecules offur when electrons are shapred between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
Explanation:
Or basically, polar molecules occur with a charge, as nonpolar molecules do not. And yes, lipids are molecules.
