Answer:
Energy is if not the most fundamental unit of everything, along with matter, space and time, thus it is one of the foundations of all science.
Explanation:
Energy in science is like words in a book, you could not read the book without words, similarly, there would be no way to do science without energy. Take this example You can only measure the *speed* of an object if it has energy.
We could look at biolgy and see how photosynthesis makes use of energy. In photosynthesis we see plant cells converting energy from the sun into usful sugars to help the plant grow.
Now we could look at astronomy and see how energy is used, If you observe stars you can see the different brightnesses and masses, which tells you alot about what type of energy conversion is happening inside the star (nuclear fusion).
Answer:
(d) None of the above
Explanation:
The pH of your stomach must be highly acidic, because the optimum pH for pepsin, the chief stomach enzyme, is 1.5.
(a) and (b) are wrong, because both conditions are basic.
(c) is wrong, because pH 7 is neutral.
The correct answers are:
• The solar wind produces the northern and southern lights
• The solar wind disrupts communication systems.
• The solar wind distorts Earth's magnetic field.
Solar winds are geomagnetic stream of charged particles radiated from the outer atmosphere of the sun. All planets are protected from solar winds via magnetic fields but planets that are positioned closer to the sun can experience degeneration of the magnetic field.
Solar winds are capable to distort and even destroy the functioning of communication satellites in outer space, such as radio and tv communication and satellite based internet services.
The effects of solar winds that are visible to naked eye are the Aurora Borealis (the Northern lights) and the Aurora Australis (the Southern Lights).
Answer AND Explanation:
There is a large number of biochemical reactions taking place in a cell at any given time. Enzymes being biological catalysts control these reactions and regulate them so that they proceed at a pace that is suitable for sustaining life. Thus enzymes regulate cellular activities. Enzymes also ensure that only the required reactions take place and progress to their appropriate extent.
