Answer:
because they can donate blood to anyone
Explanation:
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:
Explanation:
Choose all the answers that apply.
Water:
1.Can dissolve most substances
2. Has a strong attraction to itself
3.Is neither acidic and basic
water does not contracts when it freezes
,water expands i.e gets less dense when it freezes, which is unusual for liquids.
The state of nature, for Rousseau, is a morally neutral and peaceful condition in which (mainly) solitary individuals act according to their basic urges (for instance, hunger) as well as their natural desire for self-preservation.
I would assume it is choice b.
because in the summer there are more hours of light, and n the winter there are less.
