Answer:
B)hydronium
Explanation:
This chemical structure is formed when an acid is disolved into water, as the cation (H+), which comes from the acid, cannot exist as such isolated in water (H20), hence the proton (H+) will be hydrated by a water molecule (H2O)
The union between H+ and H2O is due to the pair of electrons from oxygen and positive charge from H+
I think the answer is two
<span>The answer is : Both have true necks, while eusthenopteron has no neck. </span>We know that tiktaalik is more closely related to acanthostega than it is Ichthyostega eusthenopteron because Tiktaalik and Acanthostega both have true necks while eusthenopteron has none.
Answer:
A. Cyanobacteria.
Explanation:
Both cyanobacteria and plants use water as an electron donor for the light phase of photosynthesis and make ATP and NADPH. The ATP and NADPH are used in the Calvin cycle to fix the atmospheric CO2 into glucose. The use of water as an electron donor releases oxygen gas as a by-product. This photosynthesis wherein the use of water as an electron donor releases oxygen gas as a by-product is also called oxygenic photosynthesis.
