Q: Connected to agriculture, forestry, mining, and urbanization, what is the single biggest cause of extinction today? Read this paragraph and choose the correct option from the provided answers: The single biggest cause of extinction today is habitat loss . Agriculture, forestry, mining, and urbanization have disturbed or destroyed more than half of Earth's land area. In the U. S. , for example, more than 99 percent of tall-grass prairies have been lost. Other causes of extinction today include:. Choices: - freshwater loss - hunting - global warming - habitat loss A:
habitat loss

Q: Chemical reactions follow which laws? Read this paragraph and choose the correct option from the provided answers: Chemical reactions follow the laws of thermodynamics. The First Law of Thermodynamics states that energy can be changed from one form to another, but it cannot be created or destroyed. This law is also known as the Law of Conservation of Energy. The Second Law of Thermodynamics states the energy available after a chemical reaction is always less than that at the beginning of a reaction. This is also commonly referred to as entropy. Entropy can be described as the degree of disorder in a system . That is, as energy is transferred from one form to another, some of the energy is lost as heat, and the amount of available energy decreases. As the energy decreases, the disorder in the system increases, and, by definition, the entropy increases. Ice melting provides an example in which entropy increases. Entropy essentially is a measure of the tendency of a process, such as a chemical reaction, to proceed in a particular direction. Choices: - Physics Analysis - Chemical kinetics - Archie's law - thermodynamics A:
thermodynamics

Q: Q: If particles have enough kinetic energy to completely overcome the force of attraction between them, matter exists as a what? Read this paragraph and choose the correct option from the provided answers: If particles have enough kinetic energy to completely overcome the force of attraction between them, matter exists as a gas. The particles can pull apart and spread out. This explains why gases have neither a fixed volume nor a fixed shape. Choices: - liquid - solid - vapor - gas A:
A: gas

Question: Q: Organs that produce eggs and secrete estrogen are part of what system? Read this paragraph and choose the correct option from the provided answers: one of two female reproductive organs that produces eggs and secretes estrogen. Choices: - circulatory system - digestive system - male reproductive system - female reproductive system A:
Answer: female reproductive system

Q: What cycle completes the breakdown of glucose begun in glycolysis? Read this paragraph and choose the correct option from the provided answers: The Krebs cycle completes the breakdown of glucose begun in glycolysis. If oxygen is present, pyruvate enters the mitochondria and is converted to AcetylCoA. AcetylCoA enters the cycle by combining with 4-carbon oxaloacetate. Study the diagram to confirm that each turn of the cycle (two for each glucose) stores energy in 3 NADH+H + , one FADH 2 , and one ATP (from GTP), and releases 2 CO 2 . The Krebs cycle is also known as the Citric Acid Cycle or the tricarboxylic acid cycle (TCA cycle). Choices: - bacterium - vireos - priebus - krebs A:
**Answer**
krebs
