Maintaining acidity- <span>In case the pH in the environment drops a lot (becomes very acidic), there is a flux of H ions from the cell's cytoplasm into the cell's vacuole thereby increasing acidity to required level and thus maintaining the </span><span>specific pH </span><span>in the cells internal environment as well.
Turgidity- </span><span>Vacuoles regulate the turgidity by regulating the amount of water inside the cell. </span>
cell has excessive water:<span> vacuole absorbs the water and then diffuses it out of the cell.</span>
cell lacks water<span>: water from the vacuole gets passed back into the cell thereby maintaining turgidity.

Answer:
option C = Pb
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
For example
The number of protons and number of electrons in lead are 82 and it shows its atomic number. while the number of protons plus neutrons are mass number which is 207.2 amu.
National integration is of paramount importance for a vast country like India. India is a multi-lingual and multi-racial state. From time immemorial people of diverse communities, castes and religions have been living here peacefully. In fact, unity in diversity is the very strength of her civilization.
Religious intolerance disturbs the unity, integrity and solidarity of any nation. It must be stamped out at any cost. Besides, removal of poverty and casteism, restoration of moral and political sanity are the need of the hour.
Hope this helped let me know if it was wrong. :)
2 is the resulting dna molecules would have a piece of the original dna molecule after two replication events.
<h3>What is DNA composed of?</h3>
Nucleotides are chemical building units that make up DNA. A phosphate component, a sugar group, and a single of four different nitrogen bases make up these building components. Nucleotides are joined together into strands, with the sugar and the phosphate groups switching places, to create strands of DNA.
<h3>What is human DNA called?</h3>
The 23 pairs of chromosomes in cell nuclei plus a tiny DNA molecule present in each mitochondria make up the human genome, which is a full set of nucleotide sequences for humans.
