It is a major branch of biology, but has areas of overlap with geography, geology, climatology, and other sciences. This lesson introduces fundamental concepts in ecology, beginning with organisms and the environment. Q: What is the term for the study of how living things interact with each other and with their environment? A:
A:
output: ecology

Q: Answer the following question given this paragraph: Water molecules move about continuously due to their kinetic energy. When a crystal of sodium chloride is placed into water, the water's molecules collide with the crystal lattice. Recall that the crystal lattice is composed of alternating positive and negative ions. Water is attracted to the sodium chloride crystal because water is polar and has both a positive and a negative end. The positively charged sodium ions in the crystal attract the oxygen end of the water molecules because they are partially negative. The negatively charged chloride ions in the crystal attract the hydrogen end of the water molecules because they are partially positive. The action of the polar water molecules takes the crystal lattice apart (see image below). Q: Water molecules move about continuously due to what type of energy? A:
Answer: kinetic

Answer the following question given this paragraph: Buffers are solutions that maintain a relatively constant pH when an acid or a base is added. They therefore protect, or "buffer," other molecules in solution from the effects of the added acid or base. Buffers contain either a weak acid (HA) and its conjugate base (A) or a weak base (B) and its conjugate acid (BH+), and they are critically important for the proper functioning of biological systems. In fact, every biological fluid is buffered to maintain its physiological pH. Q: What are solutions that maintain a relatively constant ph when an acid or a base is added? A:
OPTIONS:
- gases
- water
- liquids
- buffer
buffer

Answer the following question given this paragraph: invertebrates produce uric acid. Animals that secrete urea as the primary nitrogenous waste material are called ureotelic animals. Q: The primary nitrogenous waste material secreted by ureotelic animals is what substance? A:
OPTIONS:
- ammonia
- carbon
- nitrate
- urea

Answer:
urea
