Answer the following question given this paragraph: Autoimmune diseases occur when the immune system fails to recognize the body's own molecules as "self," or belonging to the person. Instead, it attacks body cells as though they were dangerous pathogens. Some relatively common autoimmune diseases are listed in Table below . These diseases cannot be cured, although they can be treated to relieve symptoms and prevent some of the long-term damage they cause. Q: What kind of diseases involve the immune system accidentally attacking healthy body cells? Choices: - contagious diseases - metabolic - inflammation - autoimmune A:
autoimmune

A: nucleus

Answer the following question given this paragraph: In a given species, chromosomes can be identified by their number, size, centromere position, and banding pattern. In a human karyotype, autosomes or "body chromosomes" (all of the nonsex chromosomes) are generally organized in approximate order of size from largest (chromosome 1) to smallest (chromosome 22). The X and Y chromosomes are not autosomes. However, chromosome 21 is actually shorter than chromosome 22. This was discovered after the naming of Down syndrome as trisomy 21, reflecting how this disease results from possessing one extra chromosome 21 (three total). Not wanting to change the name of this important disease, chromosome 21 retained its numbering, despite describing the shortest set of chromosomes. The chromosome "arms" projecting from either end of the centromere may be designated as short or long, depending on their relative lengths. The short arm is abbreviated p (for "petite"), whereas the long arm is abbreviated q (because it follows "p" alphabetically). Each arm is further subdivided and denoted by a number. Using this naming system, locations on chromosomes can be described consistently in the scientific literature. Q: What is another term for body chromosomes? Choices: - subsets - Chromosomes - quasars - autosomes A:
**Answer**
autosomes
