Answer and Explanation:

An acid has a pH that is less than 7.  A base has a pH that is greater than 7.  Something that has a pH of 7 is neutral, but since it doesn't seem that the question is asking about neutral, you can ignore that for this problem.

Situation 1:   Base

Situation 2:  Acid

Situation 3:  Acid

Situation 4:  Base

Situation 5:  Acid

Situation 6:  Base

A.  Water directly out of the tap has a pH of 7.2.  When you add carbon dioxide (blow into the water), you get a pH of 5.1.  This means that the addition of carbon dioxide makes water more acidic.

B.  The most basic solution will have the highest pH.  This means that it will be water with bleach added to it.

C.  The most acidic solution will have the lowest pH.  This means that it will be water with instant coffee.

Answer

RIBOSOMES on the ROUGH ENDOPLASMIC RETICULUM

Explanation:

This is the site of protein synthesis usually find attached to the rough endoplasmic reticulum or  freely on the cystosol,

When they are attached to the  endoplasmic reticulum they appeared as back dots which makes the surface of ER to appear rough, hence the name ROUGH ER. Smooth ER, lacks Ribosomes, and therefore appears smooth,

Ribosomes  are made up of PROTEIN AND RNA.

They are 25nm in diameter;when viewed under high magnification, where theymade up of  two sub-units  the small and large units.

The protein synthesize by the Ribosomes are passed into the sacs  of Rough E.R  for transportation,

Basically, a complete Ribosomes is refereed to as 70S for prokaryotic ribosomes and 80S for Eukaryotic Ribisomes.This refers to their sedimentation Co-efficient in Svedberg units,the Eukaryotes sediment faster than the Prokaroytes
