I believe it's "pollen".
When the pollen grains are washed down into lakes/rivers, scientists can take a sample of the sediment layers and see what plants were growing at that time. They can then make inferences about the climate and how that affected the plants growing there.
Hope this helps!

A habitat left unoccupied by native herons and egrets met the biotic and abiotic requirements of the cattle egret transplants and their descendants
Answer: Option B
<u>Explanation:</u>
The cattle egret was a species of Heron to be first seen in Greater Caribbean Basin. They acquired their name “Cattle egret” as they were found to be co-existing with the grazing cattle and feeding on the insects that come out during grazing and also feed on the ticks present on the cattle’s body.
The cattle egret within a span of few years showed a dramatic increase in its population. This was attributed by their high reproduction rate leading to their extensive population growth. They also do not have any predators devouring them. They also feed on anything and everything to survive be it insects, rodents or small reptiles. They were good flyers and they were also able to get accustomed to their surroundings and reproduce.
Answer:
A gene is a section of a double-stranded molecule known as DNA. This molecule is found within the nucleus of the cell, contained in threadlike structures called chromatin. The two strands form a double helix linked by a series of paired bases. The base adenine is always linked to thymine and the base cytosine is always linked to guanine.
