Rhenium is the very dangerous (hazard wise) it should be handled carefully and you should understand that THIS should not be taken lightly I hope this helps!:)
Answer:
- In terrestrial environments: increasing CO2 levels cause an increased photosynthetic rate
- In aquatic environments: increasing CO2 levels cause an increase in water acidity
- In both terrestrial and aquatic environments: increasing CO2 levels lead to an overall increase in the average temperature (global warming)
Explanation:
In terrestrial ecosystems, rising carbon dioxide (CO2) levels increase the rate of photosynthesis (since CO2 is one of the reactants in photosynthesis), thereby also increasing plant growth. Moreover, in aquatic ecosystems, rising CO2 concentrations increase the levels of this gas dissolved on the surface of the oceans. This increases the acidity of the oceans, thereby modifying habitats and food web structures. The increasing acidity of the oceans also reduces the amounts of carbonate, which difficult for aquatic species (e.g., corals) to form their shells/skeletons. Finally, CO2 is a greenhouse gas that contributes to the increase in the average temperature by absorbing solar radiation that would otherwise have been reflected by the Earth's surface, and this increase in the temperature negatively affects life in both terrestrial and aquatic environments.
Answer:
D: There is no wind on the moon
Answer with Explanation:
Let's start first with water on the Earth's moon. This is called "lunar water."
The moon was thought to be barren by scientists long time ago. However, they found out that there are actually <em>water reserves located in the shadowed craters.</em> It is said that the formation of this water was possible with the existence of <u>Oxygen atoms in the lunar rocks and minerals. </u>Due to the <u>solar wind</u> that blew into the place, <u>the Hydrogen ions from the wind combined with the Oxygen in order to form water.</u> So, the water that is found here is relatively fresh.
Let's go to "water on Mars." This is said to be <em>more older than the water on the moon</em> and is actually not that pure for it consists of some mixtures of rocks. It is said that billions of years ago, Mars had an abundant supply of water, but due to climate change, the supply didn't last long. As a result, the planet dried out and only the areas in the polar and mid-latitude regions have water<em> (in the form of ice).</em> This ice melts and refreezes, depending on the temperature. This is an evidence that people may possibly live on Mars.
Answer: The pH scale measures whether there is more hydroxide or hydronium in a solution.
Is important because it tells you how basic or acidic the solution is.
