Answer:
everyone was skeptical of each other's work and findings and they wanted to do their own research. Also there has benn a bunch of technological advances over the years. microscopes became better and stronger as well
Explanation:
Answer:
Water has a high Cohesion because of Hydrogen bonding. This is important as transport of water in the Xylem in plants relies on water being pulled up. Cohesion also gives the water a high surface tension, allowing small organisms, such as Pond Skaters, to walk along it.
Explanation:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
Plants obtain the hydrogen they need from water molecules. Don't try to feed your plant hydrogen gas -- your plant wouldn't know what to do with it if you did. As long as they have water, plants can readily obtain all the hydrogen they need. :)
Knowing the fact that around sixty percent of the human body is water, which consists of two hydrogen atoms and one oxygen atoms, and that other biomolecules like proteins also have oxygen atoms in their structure it's not a surprise that the percentage of oxygen in the human body mass is that high.
Even though there are two hydrogen atoms and only one oxygen atom in the water molecule, the oxygen atom has 16 times more mass than the hydrogen atom and therefore has a bigger contribution to the overall body mass.
<u>Answer</u>:
The high sea surface salinity can be observed in the Pacific Ocean, the Indian Ocean, the Arabic ocean and the Mediterranean sea.
<u>Explanation</u>:
Due to rainfall and evaporation of water from sea the density varies with varying salts and minerals concentration that aggregate at the surface. The salinity in the seawater varies according to the amount of evaporation from a particular area.
Low salinity water is found in polar and subpolar regions that are near to the equator. Regions of high salinity are observed in the seawater which is centered around 30 degrees north and 30 degrees south to the equator due to the excess evaporation in these areas.
