Answer:
c. Tunicates/Seasquirts
Explanation:
Tunicates are classified under the Urochordata phylum which is related to the Chordata phylum including vertebrates.
It would be Li and F because Li has 3 electrons which means it has an unstable outer shell as it would have 1 electron in the outer shell, however, F has 9 electrons and it needs 1 more electron in its outer shell in order to become stable so it will be shared with Li

Answer:
A) ocean deoxygenation
Explanation:
Eutrophication (eutrophication) begins when fertilizers (usually washed away by rain) reach the water from fields and other agroecosystems. Fertilizers are rich in phosphates and nitrates, which are otherwise a limiting factor for the flourishing of life in water.
With an excess of these salts, plants, especially algae, often begin to flourish. Then the number of dead algae increases, which are then decomposed by saprophytes, consuming oxygen. Thus, the concentration of oxygen in the water decreases, and thus there is suffocation and mass death of aquatic organisms that consume oxygen in the process of respiration.
I believe the correct answer is C., with such a large demand for fossil fuels and biofuels even large quantities of kelp wouldn't be able to keep up with the supply and demand.
