Ph in ground water ranges from 6.5 to 8.5 any higher would be low-quality so the answer would most clearly be Low levels of fecal coliform.

Answer:

Low levels of fecal coliform

Explanation:

The pH (hydrogen potential) of a water considered <u>pure</u> is 7. Since the ideal pH for consumption is between 6.5 and 8.5 (neither too alkaline nor too acidic), so the first statement is false.

A low level of fecal coliforms indicates lower risk of contamination by various types of microorganism, allowing water to be consumed. So the second statement is true.

How many daughter cells result from a parent cell in meiosis?
masha68 [24]

Answer:4 haploid daughter cells

Explanation:

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring.

Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

In the lab, Celia adds concentrated sulfuric acid to a beaker full of water. She touches the side of the beaker and finds the so
AlladinOne [14]

Answer: The statement is false

Explanation:

Addition of concentrated sulfuric acid (H2SO4) to a beaker full of water (H2O) will release heat energy to the containing vessel due to the breakage of strong ionic bond present in the acid.

Thus, it is an evidence of a EXERGONIC REACTION (since energy is released spontaneously). So, the statement is false
