Q5.

<span>The answer is A. In thermodynamics, the first law of conservation states that energy can never be destroyed or created but can only be transformed from one form to another. Therefore part of the electric energy was converted to light energy while the other dissipated as heat. However, the summation of the energy of these tow outputs in joules remains the same as initial electric energy.

Q6

<span>The answer is B. This is because the water in the dam is used to turn turbines hence this form of energy is mechanical energy. As the turbines turn, they turn electromagnets that convert the mechanical energy into electrical energy</span>

Ket [755]

The correct answer is - That some force lifted the rocks from the water.

The fact that there's sedimentary rocks on the tops of the mountains is an evidence that there has been some force that managed to lift upwards parts of the seafloor. Taking into consideration how slowly this force manages to lift up parts of the Earth, we can easily assume that the Earth is very old. The amount of time that is needed for a part of the seafloor to be lifted few thousand meters upwards is counted in tens of millions of years, thus giving us evidence that the Earth has been around for a very long time.

How does conservation affect biodiversity?
zalisa [80]
Conservation is the protection of an organism or a group of organisms (like an endangered species or forests).

Biodiversity is the numerous amounts of species habitated in our earth. The more biodiversity, the better.

Conservation protects biodiveristy, thus, allowing more species to survive and thrive.

Suppose molecules were unable to diffuse into and out of the cells. How might life be different if cells had to use active trans
antiseptic1488 [7]

Answer:

Cells would most probably not exist because these units of life metabolize energy molecules like glucose to harness their energy for the running of biochemical processes, like active transport, to support life. However, harnessing this energy from these energy molecules is NOT 100 percent efficient. A higher percentage of energy is lost as heat in the process.

Therefore if the cells were required to carry all molecules in and out of the cell, actively, including the energy molecules themselves (which is counterintuitive), this would require a lot of energy and would be unsustainable. This would be analogical to the counteracting and infinite loop of more fuel needed to carry the mass of the more fuel in space travel...

explain why the top of an energy pyramid does not have an arrow showing energy going back down to the bottom.
SCORPION-xisa [38]
<span>The answer to your question is that all of the energy is ultimately radiated into empty outer space as heat. The second law of thermodynamics mandates that all processes that involve the transfer of energy MUST radiate a portion of this energy into space as waste heat. This is why when you run down the street you get hot and sweaty, and this is why automobiles MUST have a functioning radiator and nuclear power stations MUST have evaporation cooling towers or else be located near a large body of water to exchange excess waste heat into, etc., etc. It is also true that the transfer of energy at each step up the food chain is very inefficient. They say it takes around 50 lbs of corn to produce one pound of beef, and it probably takes 20-30 pounds of beef to produce one pound of human tissue. The rest of the energy just goes into your living room as radiated body heat. I hope this helps.</span>
