Answer:
Option C
Explanation:
As per the paleontologists, the anchored tubular structures of fossilized Funisia dorothea showed dense clusters which are believed to be formed by mating of floating egg and sperms in the water. Also traces have been found that states asexual mode of reproduction through budding where buds were formed in the same way as that of coral, sponges etc and then these buds grew into full sized Funisia dorothea. Thus, the fossil species have the complex ability to produce both sexually and asexually.
Option C
Answer:
Polyploidy
Explanation:
Polyploidy can be defined as a rapid method of speciation that has been important in the history of flowering plants.
In plants, it involves the possession of two complete sets of chromosomes and it leads to the origin of new species.
Hence, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).
The correct answer is bioavailability.
<span>Bioavailability is an important factor in establishing nutrient requirements and it represents the degree to which food nutrients are available for absorption and utilization in the body. The amount of a nutrient in a food that the body can actually use may vary depending on age and physiologic condition.</span>
Out of the following choices, fossil fuels is the largest reservoir of carbon in the world. A couple of other reservoirs of carbon are dissolved in the ocean and in plants.
