Artificial selection, also selective breeding occurs when humans breed individuals that have specific characteristics that they want to manipulate.
Natural selection<span> and selective breeding can both cause changes in animals and plants. The </span>difference between<span> the two is that </span>natural selection<span> happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called </span>artificial selection<span>.</span>
C: The arrangement and movement of the particles in the substance. Solid particles vibrate and are compact. Liquid slide past each other and are close together. Gas particles are fast moving and very spread out.
During nitrogen fixation, bacteria breaks nitrogen gasses down into a usable form for plants.
Answer:
Electrons Can Donate - 0
Electrons Can Receive- 2
Valence - 2
Explanation:
The electronic configuration of oxygen is . Thus in the p-orbital there is deficiency of two electrons. Hence, it can receive/share electron but it cannot donate electrons. This makes oxygen as a good electron acceptor. Since there is a deficiency of two electrons in the outermost shell of oxygen, the valence of oxygen in thus -2
