' The dissolving power of water is very important for life on Earth. Wherever water goes, it carries dissolved chemicals, minerals, and nutrients that are used to support living things. Because of their polarity, water molecules are strongly attracted to one another, which gives water a high surface tension.

Polarity creates water molecules that are strongly attracted to one another. This attraction creates a high surface tension allowing water to clump together and flow through plant roots and human blood capillaries.
Water is the only natural substance that can exist in all three states of matter – solid, liquid, and gas. If water did not have these special properties, then all life would die. For example, lakes and rivers would freeze solid and all aquatic life would not be able to survive.
Water is so special that its physical properties even influences our weather. We wouldn't have rain without the water cycle and evaporation.
The correct answer here would be the zooplankton. (see the attached image)
<em>Due to the important position of the Zooplankton in the food web, any change in the environment that removes them will cause the most instability in the ecosystem. </em>
<em>Five different organisms within the food web directly depend on the zooplankton for their food four of which have no any other option. Removal of zooplanktons from the environment will directly affect these organisms and this will throw the entire food web into disarray.</em>
Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.
