In several animal species (including mammals) the X chromosome is one of the two sex-determining chromosomes. In females, the chromosome pair is XX and males, it is XY.
Since both parents will have an X chromosome, both parents will be able to pass on an X chromosome to their offspring (only males can pass on the Y chromosome).
Several abnormalities can occur when there is an extra X chromosome or a mutation on one of the X chromosomes, including Klinefelter syndrome, Triple X syndrome, and Turner syndrome.
A group of cytoskeletal structures and related layer limited organelles found at the foremost finish of grown-up commit intracellular protozoan parasites in the phylum Apicomplexa. The apical complex is engaged with connection to and infiltration of the host cell and in parasite multiplication.
Apicomplexans
: Ciliates are pretty cool, but they're not the only group of alveolates out there. Next, we've got the apicomplexans. This group is characterized by an asymmetrical collection of alveoli at one end of the cell, which is called the apical complex.
the apical complex has shaped the way it is because it helps the cell latch onto and infects other cells.That's right, apicomplexans are parasitic. There are 4,000 known species of apicomplexans, all of them parasitic, and some of them pretty nasty.
