Answer the following question given this paragraph: The electron loss and gain is easy to see in a reaction in which ions are formed. However, in many reactions, no such electron transfer occurs. In a molecular compound, electrons are shared between atoms in a type of bond called a covalent bond. Yet it is still common for reactions involving molecular compounds to still be classified as redox reactions. Q: In a molecular compound, electrons are shared between atoms in which type of bond? Choices: - Ionic - deformation - corrosion - covalent A:
covalent

Answer the following question given this paragraph: Digestive System Organs The easiest way to understand the digestive system is to divide its organs into two main categories. The first group is the organs that make up the alimentary canal. Accessory digestive organs comprise the second group and are critical for orchestrating the breakdown of food and the assimilation of its nutrients into the body. Accessory digestive organs, despite their name, are critical to the function of the digestive system. Q: What are accessory digestive organs critical for breaking down? Choices: - pathogens - enzymes - hormones - food A:
**Answer**
food
