There is no virus that currently exists that would be considered the zombie virus. However rabies is an exceptionally close one, so comparisons can be drawn. The zombie virus would most likely require a host to remain alive so allot he important functions such as the ones that allow breathing or cardiac activity will have to remain. However the virus would most likely attack the areas of the brain mostly in regards to the areas controlling judgement, perception, anger, impulse control, and appetite.
A depressant is the chemical substances that have a calming effect on people. They are also called sedatives or tranquilizers. The correct answer is 2.
Answer:
Marine ecosystem have biotic organisms like phytoplankton and photosynthetic algae that do photosynthesis and converts the atmospheric carbon dioxide into organic matter most of the carbon dioxide is released when other organisms eat phytoplankton and release the carbon dioxide through respiration.
But some of the algae and phytoplanktons die naturally get down to the bottom of the ocean where they make carbon sink. Some organisms accumulate CO₂ in their exoskeleton that is made up of calcium carbonate.
Therefore this use of carbon by living organisms in oceans brings carbon dioxide from the atmosphere to oceans. This is why the ocean plays a critical role in the carbon cycle and called carbon sink.
