1. The answer is "<span>the energy required to start the reaction".
</span>This energy is called as activation energy of the reaction. If the activation
energy is high, reaction is slow. Enzymes help to carry out the reaction by
a new path by reducing the activation energy. But the energy of reactants
and the products remain as same as without enzyme.
2. The answer is "reaction in cells would be too slow to sustain life<span>".
</span>If the activation energy is very high for the reaction, then that reaction will
be very slow and will require more time<span> to complete the reaction. Then survival is
very low. Hence, the roll of enzymes is very important to sustain life.</span>
Answer:
Electrical>thermal>light
Explanation:
Electrical energy refers to energy which is gotten from potential energy. This energy source could be a wall socket.
Thermal energy on the other hand refers to internal energy of a system where temperature is constant.
Light energy is made up of photons which transmits electromagnetic radiation which move in waves and become visible to human eye.
Therefore, the energy transformation taking place according to the question is option D.
Answer:
Elliptical galaxies, such as M87 have very little gas and dust. ... Both the largest and the smallest known galaxies are elliptical. Very large elliptical galaxies can reach 300 million light years in diameter. Dwarf ellipticals, which are very common, may contain only 1/100,000th as many stars as the Milky Way!
Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.
