Modern stromatolites – living fossils. Originating over 3 billion years ago, stromatolites are the oldest known fossils (timeline). Fossilized stromatolites were laid down as colonial structures built by photosynthesizing Cyanobacteria and other microbes.
Well, DNA contains the hereditary information in the form of sequences of nucleotides which categorize as genes, that provide the information for synthesis of structural, functional and various other proteins that in combination and or in other ways determine an organism's complex traits. The phenotype of the said organism.
I think the answer for Q2 is D but i could be wrong. sorry if i am
Hello!
Natural selection is the way that animals evolve.
The theory of natural selection is that the animals that do not have a specific trait to survive in their environment will die. The animals that do have the trait will survive. The animals that survive will then pass the trait down to their offspring, who will also likely survive because they have the trait. This is how species evolve and continue to survive in their environment.
The species evolve because only the fittest survive (this is known as "survival of the fittest"). The animals that do not have the needed traits will die and they cannot have offspring.
I hope this helps answer your question! Have a great day!
