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.
The steatite seals found in the Indus valley resemble seals found at contemporary sites in Mesopotamia.
The steatite seals are also referred to as the Pashupati seals and are found in major regions of the Indus Valley civilization.
Scientists have managed to find a variety of seals that belongs to the Harappan site of the Indis Valley civilization.
These seals have also been known to be founded in the Mesopotamia region. Scientists are researching and finding evidence that the steatite seals found in the Indus valley and Mesopotamia may belong to the same ancestors and might have migrated over time.

Which two mineral samples would be most
difficult to distinguish from each other based on
their color, luster, and streak?
diamond
Talc is the softest and diamond is the hardest. Each mineral can scratch only those below it on the scale.
