Answer:
Number 3
Explanation:
Number 3 or C is correct, "action of white blood cells when certain bacteria enter the body." This is the correct answer because white blood cells are in your body to fight off infections. some peoples immune system see these bacteria on the peanut, egg, or milk as an enemy so it tries to fight against it even though it is harmless to the body.
arbon, as with many elements, can arrange its atoms into several different geometries, or "allotropes." In pure diamond, every carbon atom is covalently bonded to exactly 4 other carbon atoms in a very specific and energetically favorable geometry. The diamond cannot be broken or scratched unless many covalent bonds are broken, which is difficult to do. In another common allotrope, graphite, every carbon atom is covalently bonded to only 3 other carbon atoms, and the atoms are arranged in sheets that are not covalently bonded to each other. The sheets can be broken apart easily, ultimately meaning that graphite can be easily scratched. Coal is composed of particles of different allotropes of carbon, and some "amorphous carbon," which has no defined geometry in its atomic structure. Without a continuous network of covalent bonds, coal is easily scratched (i.e. it is not hard).
Answer:
Sun
Explanation:
Sun is the only star in our solar system, and planets orbit around it. Our solar system is the part of Milky way (located in one of the outer bands of the Milky way), and the Milky way is the part of the Universe (Universe is made up of billions of galaxies, and Milky way is one of those galaxies). Hence, in the given options, the Sun is the part of all of the other options given.
