1) How long ago were fossil fuels created?

2) Algae grown in open pond systems are susceptible to invaders, what are they and
how do they impact the algae?

3) What are some of the resource requirements for open pond marine algae
production?

4) What are the advantages of using wastewater in marine algae growth?

How long were fossil fuels created?: long before the dinosaurs even ruled the world.

Algae grown in open pond systems are susceptible to invaders, what are they and

how do they impact the algae? Algae cultivation takes place in large ponds, or in enclosed systems enhanced with CO2. Algae cultivation has many commercial and industrial uses and looks to be a promising long-term sustainable source of biomass and oils for fuel, food, feed and other co-products. Algae have evolved to produce and store energy in the form of oil. They are more efficient than many other natural or engineered

What are the advantages of using wastewater in marine algae growth?: Idk sorry

I really hopes at least have of this helps :D

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
