Answer:
<em>The correct options are:</em>
<em>There are million of spores that are made by a single plant to help keep its population.</em>
<em>Spores can live for a long time without maturing into an adult plant.</em>
Explanation:
Spores can be described as a means of reproduction in plants like the gymnosperms.
There are millions of spores produced by a single plant so that the chances of their dispersal and maturing into new plants is maximum.
Spores also have the capability to stay dormant until the conditions become favorable for the growth of a plant from the spore.
Another adaptation of spores is that they are light weight so that they can easily be carried away by the wind.

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.
