Answer;
Water has polar bonds and is a polar molecule.
Explanation;
-Water is important in life of living organisms. The major important properties of water include; Its attraction to polar molecules
,high-specific heat, high heat of vaporization, the lower density of ice
and High polarity.
-Water's attraction to other water molecules, is one of the major properties of water. Water's polarity lends it to be attracted to other water molecules. The hydrogen bonds in water hold other water molecules together.
-Water's attraction between molecules of a different substance is called adhesion. Water is adhesive to any molecule it can form hydrogen bonds with.
Answer:
In the flask with algae, there would be photosynthesis in the presence of light which uses up the oxygen hence the dissolved oxygen in the flask with algae will be higher in the light but lower in the dark.
Answer:
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
The scientific process is important when learning about diseases because it allows to obtain reliable and valid knowledge about the different existing diseases,
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.
