The answer is clearly the option <span>A, because in the Urey/Miller experiment, they simulated Earth's early atmosphere and they simulated the lightning as electrodes, to see if single compounds or amino acids would form. Hope this is useful</span>
Yes it can be.
<span>particle can be a single atom, an atom makes the smallest possible particles.. </span>
hydrogen and oxygen I believe
Answer:
respiratory, digestive and circulatory system
Explanation:
the respiratory system brings oxygen into the lungs when you breathe. the digestive system breaks food down into nutrients such as glucose. the circulatory system transports glucose and other nutrients from the digestive system to the cells.
Answer: The correct options are b and e.
Explanation:
Thomson's model was generally known as plum pudding model which says that the electrons are distributed in an atom which is similar to the plum present in pudding.
Rutherford's model was known as the gold-foil experiment. In this experiment, he bombarded alpha particles to an atom. He thought that the particles will directly pass through the atom because it has a lot of empty space in it. But to his surprise, he found that some of the particles reflected their path and some directly reflected their way. As the alpha particles carry +2 charge and positive charges repel each other. Hence, he concluded that the atom has a positive charge which is concentrated in a small area.
Hence, the correct statements are b and e.
