Since Lithium has one valence electron that means it needs to lose it to form a stable structure. That means it's valence is equal to one. Oxygen has six atoms, in order to form a stable octet structure it needs to accept 2 electrons, therefore it's valence is 2.
Therefore two Lithium atoms bond with one oxygen atom to form Li2O
They use a internal pouch which is named swim bladder.
Explanation; Oxygen will enter a fish’s mouth, and passes through their gills. The oxygen will be taken and gets carried by hemoglobin through their bloodstream. Hemoglobin will take out some of the oxygen into their swim bladder. The amount of oxygen will show if they will sink or rise. Your question is how do they rise. If he goes up too much, the meaning of this is when the gas diffuses into their blood and out the gills.
Got this from a writing, but rephrased it.

Examples of biomes include tundra, desert etc.
Answer:
The hemoglobin of horse has 60% lower than the human's hemoglobin
This is the first stage of mitosis and meiosis whereby the specialized cell is undergoing, cell division.
The nuclear envelope starts to break down
The chromosomes start to condense during this phase, from being loose to being tight, held together at the middle.
The mitotic spindles start forming, as well from the spindle apparatus.
