Answer:
1. polarity
2. hydrogen bonding
3. High heat capacity
4. Adhesion
5. polarity
6. surface tension
7. high heat vaporization
8. hydrogen bonds form a rigid and stable network
9. Water is a polar substance and fat is a nonpolar substance.
10. Cohesion
Explanation:
Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.
The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.
High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.
When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does not interact with fat because like dissolves like.
In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.
Answer:
Must have lived before.
Explanation:
For an organism to be classified as once living, an object must have been part of a living organism or is now dead. When a flower is plucked from a plant it is hard to distinguish between when it is considered alive and when it is now considered once living. An example of a nonliving object is an apple or a dead leaf.Apr 22, 2013

Explanation:
The speed of water in a stream is affected by the gradient of the geography. The steeper the geography the higher the speed of the water flow and the higher the erosion capacity of the stream. This means the stream will be narrow and deep. There is also less meandering of the stream.
When the gradient is less steep, the stream flow slows down and so does the erosion force it bears especially on the river bed. This therefore result in a higher horizontal erosion than vertical erosion. The steam becomes wide and shallow. The stream is also more likely to meander.
The volume of water in the stream also affects the size, shape, and flow of streams and rivers. A higher volume of water has more erosion power due to the weight of the water column. The stream is, therefore, more likely to be bigger in size than a stream that carries low water volume.
