What Makes Water So Special? Why? When you hear that NASA's space probes are looking for "evidence of life" on other planets, do

you know what that means? They are looking for evidence of liquid water. Water is fundamental for all life; without it every living thing would die. Water covers about 70% of Earth's surface and it makes up 65-75% of our bodies (82% of our blood is water). Even if water might seem boring to you-no color, taste, or smell-it has amazing properties that make it necessary for supporting life.
1) How many hydrogen atoms are in a molecule of water?
2) How many oxygen atoms are in a molecule of water?
3) What holds the hydrogen atoms to the oxygen atom?
4)The shading around the molecule represents the relative density of electrons shared by the atoms. What does this indicate about the density of electrons around the oxygen atom as compared to the density of electrons around the hydrogen atoms?
5) Where is the majority of negative charge on the water molecule?

The benefits are Beaches are better protected against erosion.

Trenches created in the ocean encourage species growth.

WhatWhat are the advantages and disadvantages of beach nutrition?

Since nutrition just reduces the consequences of erosion and does not address its origins, it is usually a recurrent procedure. An agreeable setting lengthens the time between nutrient projects, cutting costs. On the other hand, a high rate of erosion might make nutrition unprofitable.

Sea turtles and rare and endangered birds alike depend on healthy beach and dunes systems. Important wildlife habitat areas that are endangered by erosion are provided by maintaining nourished beaches.

Unattached microbes are moved from the lungs to the epiglottis by the _______ effect.
lisov135 [29]

Answer:

The unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>

Explanation:

Mucociliary escalator, also known as mucociliary clearance, is one of the major defense mechanisms that protects the lungs. It describes the self-cleaning mechanism of the bronchi which are present in the lungs. The effectiveness of this mechanism depends on the properties of the produced mucus and on the quality and number of the cilia present in the lining of the airway.

Therefore, the unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>
