Flu (influenza) viruses are divided into four broad categories: influenza A, B, C or D. Influenza A is the most common type. H1N1 flu is a subtype of influenza A.
Subtypes of influenza A are categorized based on two proteins on the surface of the virus, hemagglutinin (H) and neuraminidase (N). There are many H and N subtypes, and each one is numbered. All H and N flu subtypes are influenza A viruses.
Each influenza subtype has many different strains of influenza virus. Not all strains infect people. Subtypes of influenza A viruses currently found in people are strains of H1N1 and H3N2. Each year's flu vaccine includes varieties of both of these strains and influenza B.
i hope this helps. please mark brainliest if it does :)
Assuming that this is the theory of endosymbiotic creation of eukaryotes , it supports it by showing that ancient prokaryotes such as archae have ribosomes that could have joined together, as the theory states to create the eukaryote's ribosomes that they have today (because they're so similar.)
Answer:
Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

Adenosince Triphosphate is broken down into one molecule of inorganic phosphate and a molecule of adenosine diphosphate, the energy released from this bond is captured and use to drive most cellular processes. some form of carbohydrate or triglyceride is used to generate the ATP in the first place depending upon a particular species and needs at the time
