Answer: B) FALSE Explanation: Nitrogen is found as a diatomic molecule (N2) in nature. There is a triple bond between the two nitrogen atoms.   The triple bond is pretty strong. Therefore, it needs a lot of energy to break those bonds and participate in a reaction. So nitrogen is commonly referred to as and used as an inert gas (high abundance & low cost.) However, it’s not truly inert like most noble gases. Nitrogen does react if the conditions are met. But those conditions are not exactly mild, but are not as extreme as for noble gases.   It forms nitric oxide and nitrogen dioxide with oxygen, ammonia with hydrogen, and nitrogen sulfide with sulfur.

Answer: B) FALSE Explanation: FALSE. Basophils number will not be increased when parasitic invasion occurs.   Basophils are a type of white blood cell. Although they're produced in the bone marrow, they're found in many tissues throughout your body. They're part of your immune system and play a role in its proper function.   Basophils appear in many specific kinds of inflammatory reactions, particularly those that cause allergic symptoms. If your basophil level is low, it may be due to a severe allergic reaction.   Basophils contain anticoagulant heparin, which prevents blood from clotting too quickly. They also contain the vasodilator histamine, which promotes blood flow to tissues.
