        <description><![CDATA[You are a scary lady.  This poor man who went into hospital and "was killed" by the hospital staff, well hospital staff dont kill people.  He may have contracted something whilst in hospital but the staff never killed him and most hospital aquired infections are brought in by careless and lazy patients.  I think you need to revise your wording when you write into these forums.]]></description>

        <description><![CDATA[Your answer of Tt, Tt can't be right because the man has to have the condition.  If he has it, he must be tt.
The correct answer here is that the father is tt and the mother is Tt.  Here's why:
We know he has to be tt so that he can have the condition.  But if she is TT, no children can possibly have the condidion.  So therefore, she must be Tt.
I asssume you didn't like that answer because your Punnett squares tell you that two of their...]]></description>

        <description><![CDATA[Avoiding breaking of a microscope is a matter of handling, for example: when you are moving a microscope from a place to the other, you have to  grasp it in this way: with one hand you will grab the arm and with the other hand you'll place it under it's support, in this way, you'll avoid, by supporting it, the possibility that the arm to carry by itself the entire mass of the microscope.

        <description><![CDATA[Homeostasis is the property of the body to maintain in very close limits, constants of internal environment.

The body is an energy system and organs are collections of cells. The cells have a high histologcal similarity  and the same frequency and energy homeostasis keep them together. Disruption of cellular energy is what we call disease.
Homeostasis of each system in the body is contributing to maintain the homeostasis of the entire...]]></description>

        <description><![CDATA[Histological structure of the heart:
 The heart is composed of three concentric layers: endocardium, myocardium and Epicardium. Endocardium consists of a basal endothelium located in a membrane that is continuous with the endothelial layer, composed of collagen fibers, reticulin fibers, elastic fibers, rare cells conjuctive and many sensitive nerve endings.
Myocardium consists of cardiac muscle bundles,circular  oriented atria wall, and...]]></description>

        <description><![CDATA[Green houses have become a worldwide fashion and not because they are showy, but because they save energy. The first designer and architect who talked about ecological houses was Professor Philip S. Wens, who two centuries ago thought to create human habitats  to be integrated into natural ecosystems.Wens teacher even taught a course at the University of Berkeley, explaining how an ecological house is a kind of ecosystem.
In Wens' opinion...]]></description>

Planning of the hydropower full potential  could avoid emissions of pollutants of the power system, in addition to those already avoided by setting in the function, annually representing approximately: ~ 25 million tonnes of CO2, ~ 0.45 million tons SO2, ~ 135,000 t NOx, ~ 6000 t powder, ~ 0.37 million ton CO, ~ 30 × 106 tons of slag deposits and ash emissions related to fuel local mining industry.

        <description><![CDATA[How it works
Current wind turbines running on the same principle as the ancient windmills: the propeller blades collect the wind's kinetic energy which converts into electricity through a generator.
 
How much supply
Households across the globe could be fueled by wind, if on the teritory of United States of America should be placed a wind turbine system, shows a new study made by researchers at Harvard University.

        <description><![CDATA[How it works
Geothermal energy  is a particular category of heat energy, contained in the earth's crust. The more descending deeper inside the earth, temperature rise and geothermal energy theory can be used more efficiently.
It is interesting to note that 99% of Earth's interior has a temperature above 1000 ° C, and the remaining 1% is found at a temperature above 100 ° C. These elements suggest that within the Earth's is a renewable...]]></description>

This decision has to be based on the specific situation faced by each hospital. The question provides no such information that is needed to make a meaningful recommendation of this type.
However I will give below the main criteria that should be taken into consideration for taking decision of this kind.

        <description><![CDATA[What is hydro energy has been made clear enough in previous two answers. So I will now write about how hydro power is generated, and some problem with hydro energy.
Hydro power is generated by directing water flowing with high speed, or under great pressure, or a combination to the inlet of a water turbine. This flow of water makes the water turbine rotate with great force and speed, converting the kinetic energy water velocity, and potential...]]></description>

        <description><![CDATA[Hydro stands for water. Flowing water and falling water possess the energy.In nature the rivers and falls have lot of energy which could be harnessed for the use. Electricity is the best energy that could easily be generated from this energy source of the nature. Making the tubines rotate with this energy, the mechanical energy of the moving or falling water is converted into the electrical energy which is  best and fastest portable and ost...]]></description>

        <description><![CDATA[How it works: as long as the water is flowing fast enough and in great enough volume, it can turn generators that produce electricity.
How much supply: at present, about 780 gigawatts of power are produced by hydro power worldwide.  This is about 20% of all the world's energy.  At least 100 GW more are under construction.
Problems:
It's not available everywhere.
It causes some amount of environmental degradation because it needs dams.  The...]]></description>
