How are land, air, water and living things impacted by too much carbon dioxide?
choli [55]

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 process of natural selection occurs randomly in nature. true or false
djverab [1.8K]
False in a sense because it is not random. It is just that some organisms have more advantageous characteristics than others. These genes are then passed on which makes the likelihood of the next generation surviving greater.

Q? Describe the concentration gradient of carbon dioxide across the cell membrane.
hoa [83]

Answer:

Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.

Explanation:

CO_{2} undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.

Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.

Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.
