Do Viruses have a sex life? What about bacteria??!
Question: and what sort of diets do they each have or does it depend on what sort of diseases they are causing. Details would be handy - thank you (Oh and what about brains do they have brains??)

Well, viruses aren't really alive in the sense that we think about most things being alive. They don't eat, they don't think, they actually don't have any "bodily functions" so to speak. In a sense, they are really genetic code packaged in a way that makes it easy to get inside and infect cells. The structures on the outside of the package act like keys to doors in the cells membrane, giving the virus entrance or faking it into thinking its something that it wants to have inside. Once the virus can get inside the inner layer of the cell, it acts in a way to get the cell to produce more of the virus. Basically it hijacks the cell and turns on the machinery of the cell in a way that causes the cell to inadvertently create more virus. After a while, cells usually lyse (sort of like exploding) and spill more virus out into the bloodstream.
Bacteria are a little different. Again they are not animals but microorganisms. Their internal makeup is very primitive and they are one celled organisms. They bring in nutrients (minerals, salts, water, oxygen, carbon monoxide, etc) through their membranes and process it in various microstructures in the bacteria. But they don't "eat" like you are used to thinking. They also do not have brains. Most bacteria reproduce asexually which means that in the nucleus, which holds all of the bacteria's genetic material, the DNA duplicates and then bacteria cell divides in half with each take taking half of the duplicated DNA and some of the machinery (Golgi bodies, vesicles, endoplasmic reticulum, etc) with it. Others reproduce sexually where you have one bacteria that will pass genetic material through a thread like structure called a pilus.
You asked...so why are they here? Well, they are basically the most basic forms of life. They don't have an agenda really, they just do what is necessary to stay alive, ie take in nutrients, and reproduce. Think of it like a plant-a tree doens't have an agenda other than to just live, right? Its true that they can mutate and usually how that happens is either exposure to a mutagen, like radiation, etc, or a mixup in the replication of the DNA. Sort of like if you were copying out of a book and you missed a few letters or a word or two. In some cases, you still get the point and its no harm no foul. In others, it makes a big difference in what you are reading, right? Its the same with these little replication errors in bacteria.
Bacteria are really very important. Your gut is colonized with them and what they do actually helps you in the end to digest your food. They help break down debris and dead material (like dead leaves, animals) and turn it into something that can be used by other living things. Although they are very simple, they are very important to life on this earth and they are probably the life form that will exist even when others do not. Thats why some can live in hot springs, under the earth, deep in the sea, etc.
Viruses reproduce asexually (as in make a clone of themselves) and don't eat. They, therefore, are not classified as living. Viruses don't have brains, by the way. And bacteria don't have a nucleus, and therefore don't have brains. I don't know anything about bacteria's diets (because I do believe it depends on the disease), but I hope that helps!
Bacteria has its own domain (there are three domains: Archaea, Bacteria, and Eukarya) and kingdom (Archaea, Bacteria, Animal, Plant, Fungi, and Protista) in taxonomy (living organisms' classification system)
A virus I guess is just a virus. It's not living...so...yeah...
There are six characteristics of a living organism:
1. Metabolism and Energy Use
2. Organization
3. Homeostatis (able to keep body internally consistent)
4. Growth, Development, and Reproduction
5. Irritability and Adaption
A virus does not use energy (aka does not eat), therefore it is not classified as a living organism. All living organisms MUST HAVE ALL 5 TRAITS.
yes they both do but its asexual which means they do it with them selfs
but not really, not like humans do it
look it up its really hard to explain
