On these images we see the low tide and the high tide.
Explanation:
On the two images we have the same place but with two contrasting views. On the picture on the left we see that the water level is higher and the boat is floating, while on the picture on the right we can see that the water level is lower and the boat is on dry land. This is actually a representation of low tide and high tide.
The high tide occurs twice in 24 hours, on roughly 12 hours. It is the process when the water level rises and comes further toward the land. The low tide also occurs twice in 24 hours, and also on every 12 hours. It is the process of retraction of the water toward the sea. These processes occur because of the gravitational pull of the Moon (primarily), and to a lesser extent of the Sun as well.
Answer:
False
Explanation:
The primary productivity is higher than the secondary productivity, or any other productivity for that matter. The primary productivity comes from the producers, and it basically represents the total biomass of the producers. The producers outnumber and outweigh all other organisms by far, so they produce significantly much more biomass than any other type of organisms, thus being rated on the top for productivity.

Answer:
The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.
Explanation:
The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.
The process of <u>cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions</u> where, from a glucose molecule, energy is obtained in the form of ATP molecules.
Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:
<em>C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂</em>
This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.
For the other options it is important to mention that:
- <em><u>C₆H₁₂O₆</u></em><em> is the substrate from which cellular respiration takes place.
</em>
- <em><u>ATP </u></em><em>is the final product of cellular respiration, translated into energy to be used by the cell.</em>
