Answer: divergent boundary where crust plates are.
Explanation: The Mid-Atlantic Ridge is a mid-ocean ridge, a divergent or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.
Answer:
Trichomoniasis
Explanation:
Trichomoniasis is an sexually transmitted disease that affects around 30% of world population. The common symptoms are frequent urge to urinate, vaginal bleeding, burning sensation during urination.
The causative agent of trichomoniasis is a protozoa called <em>Trichomonas vaginalis</em>. This protozoan can be transfer through the genital contact. The protozoa can easily be transfer from affected individual to the healthy individual.
Thus, the correct answer is option (3).
Production of energy using water power
Using electricity or energy-saving products, creation of technology to capture sulfur dioxide are the processes that can be taken into account.
<h3><u>Explanation</u>:</h3>
Acid rain is a very serious issue in the urban areas now a days. Acid rain forms due to the excessive production of gases like sulphur dioxide, nitrogen oxides etc which are beyond the level of absorption by the environment. This gases go up in the atmosphere and they mixes with cloud water to form corresponding sulphuric acid and nitric acid. These acids come along the rain and decrease the pH of the water bodies as well as soil.
If we start using water as the source of our energy production, then we can eliminate the use of coal and other fossil fuels which are chief sources of these gases.
If we can grow some technology to capture these gases before they are released into the environment, then also there will be less problems. Technologies like alkali bath are not so operative in large scales.
We can use electricity in boilers and other places where still, fossil fuels are brunt to produce the heat so that sulphur oxides don't come out.
Solar Energy:
Of all of the solar technologies, solar thermal systems are by far the most straightforward and the best developed. Architectural Designs are being developed to conserve solar energy by taking advantage of the site and building materials which in turn transform a building into a solar collector. There are many mechanical moving parts within an active solar thermal system.
The makeup of Solar Energy Systems and how solar panels work is best described as follows:
The solar collector (basic unit) is a panel generally made from aluminium, glass, plastic and copper. These panels when fixed to a roof absorb direct sunlight and transfer heat to a fluid that passes through the collector or basic unit. This fluid then flows through pipes into the building where it then heats water or warms the rooms.
Sunlight is converted into electricity by Photovoltaics (solar cells). These solar cells produce an electromotive force in a material as a result of its absorbing ionizing radiation.
In the case of semi-conductors, significant conversion efficiencies have been achieved however in theory this effect is also apparent in solids, liquids and gases. The most commonly used component of the solar semi-conductors is Silicon.
There are a range of different solar power systems currently available. These are
Grid connect solarStand-alone or off-grid solar systemsHybrid solar systemsPortable solar power systemsSolar batteries
More information can be found about these types of systems here.
The usefulness of these Solar Cells in the Space Exploration Program has already been proven in India as well as other countries in the world. The Bhabha Atomic Research Centre in Bombay, have successfully developed Solar Cells which have been tested in the satellite Bhaskara and which also meet part of the power requirement abroad (Gupta, 1981). The likeliness for large-scale power generation to meet energy requirements on earth is even bigger.
Geothermal Energy:
Geothermal Energy is a clean and sustainable power source that comes from heat in the centre of the earth.
Hot molten rock called magma deep inside the earth’s surface has in some places pushed up towards the earth’s crust, resulting in the range of geothermal energy resources to be expanded.
Geysers are produced when water flows over these hot rocks causing steam to rise through crevices in the earth’s crust, which can then be converted into electricity.
There are three types of geothermal energy technologies:
Geothermal Electricity Production: using the earth’s heat to generate electricity.
Geothermal Direct Use: using hot water within the earth to produce heat directly.
Geothermal Heat Pumps: heating and cooling buildings using the shallow ground.
It has only recently become evident that Australia has potential for geothermal energy production, because of the perception that the resources were only found in locations that have active volcanism (which Australia doesn’t have).
However, it has been uncovered that Australia is home to suitable hot sedimentary aquifer and hot rock resources.Two projects are under development in Australia to utilise these resources, and they are hot sedimentary aquifers (HSA), and enhanced geothermal systems (EGS or hot rocks).
Answer: linear or circular. include genes encoding viral proteins: capsid, envelope proteins, any polymerase not found in the host cell. viruses may have a lipid envelope.
