What does pH answer mean?

The pH of a solution indicates the acidity or basicity of the answer. A solution is said to be neutral if the pH is 7, if the pH fee is less than 7 then it is acidic in nature and if the pH cost is greater than 7 then the solution is simple in nature.

What does pH stand for?

Ph may appear as it belongs at the periodic desk of factors, however, it's truly a unit of size. The abbreviation pH stands for ability hydrogen, and it tells us how an awful lot hydrogen is in drinks—and the way active the hydrogen ion is.

What's the pH of a solution?

PH is a measure of the attention of H+(aq) ions in an answer. The attention of H+ ions may be stated in mol dm(-three), but the use of the log(10) feature simplifies the numbers concerned. Definition: pH is the terrible logarithm to base 10 of the hydrogen ion awareness in an aqueous solution.

Which cell organelle is where proteins are made? A. nucleus B. ribosome C. vacuole D. mitochondrion

Answers

Answer: Ribosome

Explanation:

The protein formation inside the body takes place in the cell organelle named ribosome. Protein is a every essential component of the body.

It serves many functions in the body of all the eukaryotic organism. It is found on the body surface as the body guard to kill the invading pathogens, all the enzymes inside the body are protein.

The ribosomes inside the cell can be attached to the endoplasmic reticulum or can be found floating inside the cell.

The proteins are synthesized both by the floating and attached ribosomes. The proteins produced by the floating ribosomes are used inside the cell and the proteins made by rough Endoplasmic reticulum are most of the time sent outside the cell.

Answer:

B. ribosome

Explanation:

In the ribosomes, the codons get paired with anti codons to create a polypeptide or protein.
