Feel free to ask away already!

Grass, weed, tree, just some of the sources of pollen that can send our allergies off.

In my experience, I’ll react (itchy eyes, etc.) for a day or two, then it will wane. Certainly the pollen I’m reacting to doesn’t magically disappear in a day. What processes do I have to thank that allow me to suffer only a relatively short time? Are the allergen in pollen unstable and break down quickly on their own? Are there bacteria or other life forms that are helping to break the allergens down?

Tearing eyes and draining noses want to know!

This is more of an evolutionary biology question but I thought I'd ask bc I couldn't fibd anything on it

Specifically what I'm wondering is why the majority of animals seem to have their brain or central nervous system located at a specific end of their body rather than near the center of mass where you think it'd be safest? I thought of this as I watched a centipede have its tail end attacked and noticed that its head and tail end look quite similar, assumedly for the purpose of fooling would be predators, and wondered why it didn't just put its brain in the middle so it wouldn't be vulnerable at the ends.

Moreover, why do we even need heads? Why did almost every animal evolve to have all their sensory organs in one spot instead of spreading them out. Why is my face where my face is basically. Are our bodies really built to be the most durable and efficient for the terrain they evolved in and why are they all so similar?

How big would a pelican need to be to generally be capable of swallowing grown humans whole? What body changes would we expect to see in such an organism? Thanks in advance for your educated insight. Also sorry for the split infinitive. Just call me Captain Kirk!

Recently, I have been reading more and more articles saying that Alaskan lupines (Lupinus nootkatensis) are hindering the growth of trees in Iceland. Unfortunately, however, I could not find any valid reasons why this is so? The story goes that in 1945, the then director of the forest service brought two spoonfuls of seeds from Alaska to amfortify the nutrient-poor Icelandic soil, stop erosion in Iceland and prevent sandstorms. After all I know, lupines draw nitrogen from the air and store it in the soil. So why is that not good for native tree species, such as birch or larch?

There's herbivores, omnivores, and carnivores, but is there any category of animal life that can sustain itself on anything else that isn't related to living organisms?

Is the only known example of this at the moment basically...Plants, give or take the particular species & how one may interpret the question of relation to other life?

There are 5 kingdoms; Kingdom Animalia, Kingdom Plantae, Kingdom Fungi, Kingdom Minera, and Kingdom Protistae. Why isn't there another one for viruses, since they fit in neither of these kingdoms, due to the lack of DNA?
