A marine algae called Emiliana huxleyi can overgrow, creating an algal bloom covering thousands of square kilometers of ocean. A
malfutka [58]

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.

What does divine creation mean? did charles darwin agree with this idea?
tatyana61 [14]

Answer:

The term creationism most often refers to belief in special creation; the claim that the universe and lifeforms were created as they exist today by divine action, and On the Origin of Species reflects theological views. Though he thought of religion as a tribal survival strategy, Darwin still believed that God was the ultimate lawgiver, and later recollected that at the time he was convinced of the existence of God as a First Cause and deserved to be called a theist.
