Answer 1

Answer:

Explanation:

For example the enzymes in tears and saliva break down bacteria. The stomach produces acid which destroys many of the microbes that enter the body in food and drink. Urine as it flows through the urinary system flushes microbes out of the bladder and urethra.

Abnormal development can occur in the human body due to various reasons. Genetic or inherited causes include chromosomal defects caused by too few or too many chromosomes, or problems in the structure of the chromosomes, such as Down syndrome and an extra copy of chromosome 21 and sex chromosome abnormalities.
