I would go with D, speaker. A poem is written by an author, but the author isn't always the speaker.
Answer:
Amylose and Amylopectin contain alpha bonds therefore, CAN BE DIGESTABLE BY HUMANS.
<u>NOTE:</u>
It isn't much detailed because those are options and they have to be chosen I have just given the answer and not a fully detailed paragraph on it.
4. E=mc²
Explanation:
The best approximation of the energy released during a nuclear fusion process can best be determined using the Einstein equation.
In nuclear reactions, mass and energy are equivalent:
E = mc²
E is the energy
m is the mass
c is the speed of light
- In nuclear reactions, some of the mass is converted into the energy.
- Therefore mass is not conserved in such equations.
- This is why they release huge amount of energy.
- From this equation, we know that the more mass loss, the more the energy that would be produced.
- In a fusion reaction, two light nuclei combines to form a heavier one.
