Answer:
Explanation:
As we know that the formula for pH is
![pH = -[log H+]\\](https://tex.z-dn.net/?f=pH%20%3D%20-%5Blog%20H%2B%5D%5C%5C)
It is also given in the question that one pH unit represents the 10 fold change in the concentration of hydrogen ion.
Now for lemon juice whose pH is 2, hydrogen ion concentration is equal to
And for pure water whose pH is 
, hydrogen ion concentration is equal to
Thus, the H+ ion concentration in lemon juice is 
times greater than the pure water.
Answer:
Cytosine & Guanine
Explanation:
Living organisms contain in their cell a biomolecule responsible for the storage and transmission of genetic information called NUCLEIC ACID. DNA is one of the two nucleic acids found in living cells. However, the DNA molecule is a polymer made up of monomeric units called NUCLEOTIDES.
Nucleotides of a DNA are made up of three components namely: 5-carbon sugar (deoxyribose), phosphate group, and a nitrogenous base (Adenine, Guanine, Cytosine and Thymine). Hence, based on the question, Cytosine & Guanine are the components (nitrogenous base) found in the DNA of all living organism.
Answer:
2Na + 2H2O - 2NaOH + H2
Explanation:
WATER MOLECULE WILL BREAK INTO H AND OH
OH COMBINES WITH NA AND FORMS NAOH AND GIVES H2
The animal is an Amphibian.
Hope this helped. :)
A diverse population is usually more stable because it is better at resisting disease because of simple biology.
