Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern. <sep>Where is the structure located, that warblers use to detect the magnetic fields of Earth?<sep>Pancreas
No

 The one person who, by his interference, could have settled all doubts was debarred by circumstances from interfering in the matter.  Wykham Delandre had quarrelled with his sister--or perhaps it was that she had quarrelled with him--and they were on terms not merely of armed neutrality but of bitter hatred.  The quarrel had been antecedent to Margaret going to Brent's Rock.  She and Wykham had almost come to blows.  There had certainly been threats on one side and on the other; and in the end Wykham, overcome with passion, had ordered his sister to leave his house.  She had risen straightway, and, without waiting to pack up even her own personal belongings, had walked out of the house.  On the threshold she had paused for a moment to hurl a bitter threat at Wykham that he would rue in shame and despair to the last hour of his life his act of that day.  Some weeks had since passed; and it was understood in the neighbourhood that Margaret had gone to London, when she suddenly appeared driving out with Geoffrey Brent, and the entire neighbourhood knew before nightfall that she had taken up her abode at the Rock.  It was no subject of surprise that Brent had come back unexpectedly, for such was his usual custom.  Even his own servants never knew when to expect him, for there was a private door, of which he alone had the key, by which he sometimes entered without anyone in the house being aware of his coming.  This was his usual method of appearing after a long absence. <sep>Who is the one person who could have settled all doubts just by interfering?<sep>Margaret
No

The center of an atom is held together by powerful forces. This gives them a huge amount of stored energy. This type of energy is called nuclear energy. This energy can be released and used to do work. This happens in nuclear power plants where they split apart the nucleus of an atom. This splitting apart is called nuclear fission. Another type of nuclear energy happens in the Sun. Here the atoms nuclei are not split apart. Instead, the nuclei of the atoms are fused, or joined together. This process is called nuclear fusion. Some of the suns energy travels to Earth. This energy from nuclear fusion warms the planet and provides the energy for photosynthesis. <sep>What happens to the energy of an atom if the nucleus is split apart?<sep>The energy is released

Yes
