I looked it up and got biotic.<span />
Protist are eukaryotic organisms that cannot be classified as a plant animal fungus. They are mostly unicellular, but some like algae, are multicellular. Kelp, or “seaweed” is a large multicellular protist that provides food, shelter, and oxygen for numerous underwater ecosystems.
The alleles of offspring vary, some are dominant and some are recessive, meaning that some traits get passed down and some don't, for example,: a dominant trait might be blue eyes, a parent would have blue eyes, and pass that dominant trait to their child so that the child would also have blue eyes, recessive traits are traits that skip a generation.
For example a grandparent might have black hair, but their child won't have black hair, however, their grandchild will have black hair, therefore the black hair trait is recessive and skipped a generation
Hope this helps
Both it.) And I.) Can be answers. You could argue either one is right.
I think it the answer is C ( The relationship between the bacteria and the ticks is commensalism, and the relationship between ticks and humans is parasitism.
