Answer:
They are used as an indicator organism for pathogenic bacteria.
Explanation:
Coliforms are bacteria found in digestive tract of animals and humans. They are non-pathogenic, easy to culture and are used as an alternative indirect testing for presence of other microorganisms. Coliforms thrive in exact environmental conditions like other pathogenic bacteria, thus often used to indicate whether they are bacteria found in drinking water and swimming pools that might end up causing infections.
Therefore the existence of coliforms in water easily indicates feacal contamination.

Somatic cells are produced through the cell division process of mitosis. ... Cells with two copies of each chromosome are called diploid. Sperm and egg cells, called gametes, are formed through meiosis, which is a slightly different cell division process that results in the cells having only one copy of each chromosome.

Human body cells (somatic cells) have 46 chromosomes. A somatic cell contains two matched sets of chromosomes, a configuration known as diploid. ... Human cells that contain one set of 23 chromosomes are called gametes, or sex cells; these eggs and sperm are designated n, or haploid.

Answer:Hopefully you feel comfortable with what a number line is. A graph is two number lines (called the x axis and the y axis) which cross each other at zero. A linear equation is a relationship between the two number lines. So if I gave you the linear equation “y=x”, this means if you pick a number on the x axis, the equation tells you what the number is on the y axis. So if you picked x=10, then you would know y=10. You can then draw a point at the co-ordinate (10,10), the point is there to tell you that the equation is true at that point. You can then pick another x, say x=9, then you know y=9 and you can put a point at (9,9), so you know the equation is true at that point also. You can do this with any number that you pick for x, and if you did that for every number, all the points you draw would turn into a line.
