Limulus polyphemus are the source of cells for the LAL test used to detect bacterial contamination of surgical tools.
Limulus amebocyte lysate (LAL) is an aqueous extract of blood cells from the Limulus polyphemus which is used in LAL test. LAL test includes the reaction between LAL and bacterial endotoxin lipopolysaccharide (LPS), which is a membrane component of gram-negative bacteria. LAL test is widely used for the detection and quantification of bacterial endotoxins.

1) a series of circulation cells for the tropics, (2) a series for the polar regions and (3) a very dynamic series of cells in the midlatitudes
Answer:
Disease resistant traits and selective breeding.
Explanation:
Disease resistant traits in wild plants and animals are helpful if these traits are present in our plants and animals in order to maintain its high quality. We can modify both our meat and plants with the help of selective breeding of high quality plants and animals. Due to selective breeding, we can achieve the desired characteristics through modification in our plants and animals.
