Answer:

10.5minutes

Explanation:

DRT = 90%

Cells present = 10^6

Autoclaving = 1.5 minutes

Solution:

10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5

it would take it approximately 10.5 minutes to kill 10^6 of the cells.

If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.

Water has special characteristics because of the nature of hydrogen bonds what are they?
Amanda [17]

Water has special characteristics because liquid water is denser than ice and ice floats on top of liquid water​.

Answer: Option A & D

<u>Explanation:</u>

A water molecule is formed by the covalent bonding between two atoms of Hydrogen atom with one atom of Oxygen. In water, the Hydrogen bonds are the one that keeps the water molecule intact.  

When the water molecule freezes the bonding becomes weak as they are separated and set apart which makes the liquid water denser than ice. Normally a substance floats if it is less dense. Ice floats because it is less dense than water.
