The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms. This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
In haplodiploidy, males receive one half of the chromosomes that females receive, including autosomes. In an X0 sex-determination system, males and females receive an equal number of autosomes, but when it comes to sex chromosomes, females will receive two X chromosomes while males will receive only a single X chromosome.
Bee stings differ from insect bites, with the venom of stinging insects having considerable chemical variation. The reaction of a person to a bee sting may vary according to the bee species. While bee stinger venom is slightly acidic and causes only mild pain in most people, [1] allergic reactions may occur in people with allergies to venom ...
The western honey bee or European honey bee (Apis mellifera) is the most common of the 7–12 species of honey bees worldwide. [ 3 ] [ 4 ] The genus name Apis is Latin for 'bee', and mellifera is the Latin for 'honey-bearing' or 'honey-carrying', referring to the species' production of honey.
Oxygen-transport systems were long thought unnecessary in insects, but ancestral and functional hemocyanin has been found in the hemolymph. [3] Insect "blood" generally does not carry hemoglobin , although hemoglobin may be present in the tracheal system instead and play some role in respiration.

The Africanized bee, also known as the Africanized honey bee (AHB) and colloquially as the "killer bee", is a hybrid of the western honey bee (Apis mellifera), produced originally by crossbreeding of the East African lowland honey bee (A. m. scutellata) with various European honey bee subspecies such as the Italian honey bee (A. m. ligustica) and the Iberian honey bee (A. m. iberiensis).
Nest cavity ranges from 10 to 15 liters with a round comb structure that tends to be uneven. A. c. japonica will also dismantle an old hive before moving on to a new one. [4] while western honeybee colonies can have over 50,000 worker bees, a Japanese honeybee colony's maximum number of worker bees is 6,000 to 7,000
