Burro led and Emily……..

Answer:

aneuploid

Explanation:

The typical number of chromosomes in each human cell is 46. These include 22 pairs of “autosomes” (which refers to all chromosomes that are not sex chromosomes) and a pair of sex chromosomes, either an X and a Y (which makes for a male) or two Xs (female). That means the genetic signature for a person with 46 chromosomes is either 46-XY (males), or 46-XX (females).

Any variation from these typical numbers is referred to scientifically as an “aneuploidy.”

The outer layer contains endotoxins that cause these symptoms

Explanation:

Endotoxins are lipopolysaccharides complex associated with the outer membrane of Gram-negative bacteria (e.g., Escherichia coli, Salmonella, Pseudomonas, Neisseria, Shigella, etc). These endotoxins are well-known to cause inflammation and fever, which are natural responses of the immune system. Inflammation stimulates white blood cells (leukocytes) to attack pathogenic harmful microorganisms. Moreover, the increased body temperature (fever) also can inhibit the growth of many harmful microorganisms since human pathogens are mesophiles, i.e., they exhibit an optimum growth at moderate temperature (35 °C).
