Hello! Allow me to help!
Your question: Prove that air is a mixture of gases
My answer: Air is a mixture and not a compound because: Air does not have a formula like a mixture, while compounds have a fixed formula. When air is formed by gases, there is no energy change. Components of air can be physically separated.
Why is this correct? Good question! Allow me to explain: Air is composed of various gases such as nitrogen, oxygen, carbon dioxide, inert gases and so on.Moreover , dust particles and water vapour are also present in the atmosphere because of which air is mixture.
Hope this helps! UwU

<span>Higher amounts of nitrogenous compounds will increase algal blooms, leading to less available oxygen in the water, and decrease biodiversity.

Let's take a look at each option and consider them in light of our knowledge.
1. These compounds will combine into larger molecules as they interact in the nitrogen cycle and become food for fish and other animals, increasing biodiversity.
* This has some problems. Yes, the fertilizers will cause an increase in the food supply, but that doesn't spontaneously cause an increase in biodiversity. The only way to increase the biodiversity is to introduce new organisms. And this isn't such a mechanism. I won't pick this choice.
2. The water cycle will remove excess fertilizer naturally through evaporation, with no impact on biodiversity.
* There's some issues here as well. Think about how much fertilizer runoff is considered a pollution issue. If this option were true, then we wouldn't be seeing so many news articles complaining about fertilizer running causing pollution problems. So this answer isn't any good either.
3. Nitrogenous compounds will be recycled into carbon compounds to create new organisms and increase biodiversity.
* Still running into the "spontaneous increase in biodiversity" issue here. How would more carbon compounds suddenly increase the biodiversity? This answer isn't any good either.
4. Higher amounts of nitrogenous compounds will increase algal blooms, leading to less available oxygen in the water, and decrease biodiversity.
* This is a real problem. Some might think that "Algae is a plant. Plants produce oxygen. Why would more algae cause the oxygen supply to decrease?" Well, the answer is pretty simple. Individual algae cells don't live very long. So you have a log of algae being produced. Releasing oxygen to the air, and then dying. And the dead algae then proceeds to decay, which does consume dissolved oxygen in the water. Which does cause the death of fish and other animals that are dependent upon that dissolved oxygen. And that does reduce the biodiversity in the area. So this is a reasonable and correct answer.</span>
Answer:
B
Explanation:
Animal cells don't have a cell wall and are multi-cellular. Plants have cell walls, fungi can be unicellular, and archaebacteria are prokaryotic.
