Provides support and energy
Answer:
<em>Carbon</em>
Explanation:
<em>Emiliana huxleyi</em> is a coccolithophore, a eukaryotic unicellular alga that grows in the oceans of the world, from the tropic to the subarctic areas. It has an external calcite skeleton, which is equivalent to aproximately one thirth of the CaCO₃ marine production. Under favorable conditions, this species can overgrow producing blooms, which are giant aggregations that can cover several square kilometers. These blooms can seriously affect the aquatic ocean life on a global level by running out nutrients and forbidding sunlight to reach certain depth levels.
When these blooms are infected with a specific virus called EhV, their calcic carbonate exoskeletons explode dispersing particles in water and releasing carbon and minerals back to the oceans. EhV viruses act as a biological control for these blooms.
C. He compared two groups of finches to illustrate natural selection
(although it was actually 4 groups of finches from 4 different islands)
Answer:
The reverse of the pump is for the cell to absorb water and store it inside the plasma membrane this happens when the organisms are in a hypotonic solution.
Explanation:
Answer:
The frequency is higher in case of echolocation sounds produced by Bottlenose dolphins. It falls in the range 40,000 Hz to 130,000 Hz, while the calls made by blue whales lies in the range of 30 Hz to 8,000 Hz.
However, the blue whale calls last a lot longer than the echolocation sounds made by the dolphins. A typical blue whale call is between 10 to 30 seconds long, while the dolphin's click is only 50 to 128 microseconds long.
Hope that answers the question, have a great day!
