b. in the North Pacific Ocean
c. in the Southern Ocean
d. in the eastern Pacific Ocean just north of the equator
Discuss how global warming might make it harder for the wind/currents to mix the different ocean layers. Apply that knowledge to how global warming would affect marine life species, such as mollusks and limpets.
Please answer both parts. break down each idea and explain.
Explain how ocean acidification is likely to affect molluscs. Describe the long-term effects of this process on human economies.

- A zoologist is investigating an unidentified marine animal specimen. They note that this creature has radial symmetry along its short axis, but has bilateral symmetry in a perpendicular axial plane. In addition, its peripheral surface appears to have several lines of cilia used for movement in the water. Which phylum is most likely to contain this specimen? Group of answer choices A. Annelida B. Mollusca C. Cnidaria D. Ctenophoraarrow_forwardchoose the correct answer 1) What do the banded formations in marine sediments indicate? A. Early cyanobacteria probably were producing oxygen when the sediment was deposited. B. Purple sulfur bacteria were the dominant life form in the seas during that time. D. The pH value of the early seas was quite low due to the excretion of organic acids from the fermentation by prokaryotes. C. The early atmosphere was very reducing. 2) Which of the following is not evidence that chloroplasts and mitochondria originated as prokaryotic endosymbionts of larger cells? A. They contain circular DNA molecules not associated with proteins. B. Their membranes have enzymes and transport systems that resemble those found on the plasma membranes of prokaryotes. D. Their ribosomal RNA is more similar to that of eubacteria than to the RNA of ribosomes in the eukaryotic cytoplasm. C. They contain their own genome and produce all their own…arrow_forwardImagine that the ocean plankton suddenly disappeared. What effect would that have on the nekton and benthos?arrow_forward
- The resource page discusses an increasing threat of nuisance flooding in North Carolina. To understand what nuisance flooding is, you have to have a basic understanding of tides. How are tides generated and propagated around ocean basins? Explain how the factors that control tides change over the course of one month and tie that back to the problems with nuisance flooding. Please be sure to reference your article (include information about it) in your answer and define any scientific terms your audience may not know.arrow_forwardImagine that humans have significantly reduced the amount of greenhouse gas emissions on Earth, but the planet is still warming due to past emissions. How might solar radiation management be implemented to rapidly cool the planet and prevent further impacts of climate change? a. aerosols can be removed from clouds to decrease the amount of cloud condensation nuclei b. sulfur dioxide can be injected into the stratosphere to decrease albedo c. sulfur dioxide can be injected into the atmosphere to increase albedo d. shipping can be regulated to reduce the cloud condensation nuclei of ship tracksarrow_forwardWhat do the banded formations in marine sediments indicate? A. Early cyanobacteria probably were producing oxygen when the sediment was deposited. B.

- A research team conducted a project where they artificially increased the CO2 levels in tanks containing corals. They found an inverse relationship between reef building and atmospheric CO2. This experiment __________. Options: A. is not possible. Increased CO2 should not affect the reef, as it is a relatively inert gas. B. represents the situation in the pre-industrial age, with less reef-building occurring than now C. indicates that marine ecosystems are unlikely to be affected by rising CO2 levels D. indicates that available calcium carbonate levels will increase with increasing levels of CO2 E. indicates that even though the oceans may be good sinks for CO2, there will be negative impacts of increasing levels of atmospheric CO2 beyond the greenhouse effectarrow_forwardMany organisms living in estuaries experience freshwater and saltwater conditions each day with the rising and falling of tides.
