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:
can occur instantaneously through formation of polyploid offspring.
Explanation:
In Sympatric speciation, species are not geographically isolated but reproductively isolated from each other as two varying types of species is observed to have emerged from one original. Take for example, in Fruit Flies where each species have different food choices, making each one to feed on separate fruits.
"SYMPATHETIC SPECIATION do occur instantaneously through formation of polyploid offspring (it has double the normal amount of chromosomes)". And it's most likely take place due to natural selection. It relies on the process of disruptive selection acting against hybrids.
Explanation:
a thermocline is an abrupt temperature gradient in a body of water such as a lake, marked by a layer above and below which the water is at different temperatures.

Answer:
The Nucleus
Explanation:
The Nucleus is an organelle enclosed in a nuclear membrane present in all Eukaryotic. It controls the activities of the cell by regulating the expression of genes in the Deoxy ribosenucleic acid (DNA) stored in it. It controls the hereditary traits of an organism by regulating cell division.
It harbors the nucleolus, which contains the Ribosenucleic acid (RNA) that conveys the instructions in the DNA and also serves as a template for protein synthesis (responsible for phenotypic traits) in the ribosome.
