Answer & explanation:
The cell was discovered in 1669 by the English scientist Robert Hooke when looking at a piece of tissue in a two-lens microscope. Hooke was able to visualize small cavities in the experiment piece, then naming such cell cavities.
Only a century and a half after the discovery of the cell, that the Cell Theory was launched, replacing the theory of spontaneous generation (or abiogenesis).
Before that, many scientists were already busy understanding the structure and functioning of the cell, generating knowledge that became fundamental to the development of biology, specifically cytology, a branch of science that studies the structure, functions and development of cells.
The flooding of half part of the forest have successful separate the population of frogs in that ecosystem into two different set of frogs. This is an example of allopatric speciation, that is, the population become separated as a result of geographical barrier. This separation will make the two set of frog population to become new species. On the long run, the two species may become unable to relate sexually.

To keep in the stored enzymes so it can keep synthesizing at night, even when there is no sunlight. -- Stomata serve two main functions - they allow carbon dioxide to reach the cells in the leaf where the majority of photosynthesis takes place and they allow water to be transpired out off the leaf. During the day, stomata are generally open to allow photosynthesis to take place as quickly as possible. At night, when the lack of light means photosynthesis can't take place, many plants close their stomata to reduce water loss. There is one group of mainly desert plants, known as CAM plants, that keep their stomata closed during the day when water loss would be greatest, and open them at night, using a biochemical method to effectively store carbon dioxide in the leaf overnight.
