Q: Answer the following question given this paragraph: 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. Q: Chemical reactions follow which laws? A:

OPTIONS:
- Physics Analysis
- Chemical kinetics
- Archie's law
- thermodynamics

A: thermodynamics

input: OPTIONS:
- decomposition energy
- reaction energy
- positive energy
- activation energy Now, answer this question: Answer the following question given this paragraph: All chemical reactions need energy to get started. Even reactions that release energy need a boost of energy in order to begin. The energy needed to start a chemical reaction is called activation energy . Activation energy is like the push a child needs to start going down a playground slide. The push gives the child enough energy to start moving, but once she starts, she keeps moving without being pushed again. Activation energy is illustrated in Figure below . Q: What is the amount of energy required to begin a chemical reaction known as? A:
A:
output: activation energy

Answer the following question given this paragraph: Evolution focuses on past life forms and how they turned into present life forms. The history of life on Earth demonstrates how the first cells formed, turned into simple life forms, and then became more complex plants and animals. The studies of Charles Darwin have reshaped and influenced all aspects of biology. The myriad evidence of evolution demonstrates the importance of the theory of evolution by natural selection. Lastly, the current focus on evolution demonstrates that evolution is a continuous and ongoing process that continues today. Q: Focused on evolution, the studies of what man have reshaped and influenced all aspects of biology? A:

OPTIONS:
- Linnaeus
- scopes
- Albert Einstein
- charles darwin

Answer: charles darwin

Problem: OPTIONS:
- cube
- conical
- cylindrical
- spiral
Q: Answer the following question given this paragraph: The spiral structure in the picture is a large organic molecule. Can you guess what it is? Here's a hint: molecules like this one determine who you are. They contain genetic information that controls your characteristics. They determine your eye color, facial features, and other physical attributes. What molecule is it?. Q: What is the distinctive shape of the molecule that contains genetic information? A:
Answer: spiral

Problem:OPTIONS:
- Water
- fuel
- heating
- energy

Answer the following question given this paragraph: Ecosystems require constant inputs of energy from sunlight or chemicals. Q: What do ecosystems require constant inputs of? A:
****
A: energy

Problem:OPTIONS:
- circulatory system
- lymphatic system
- digestive system
- nervous system

Answer the following question given this paragraph: Some people recover from spinal cord injuries. But many people are paralyzed for life. Thanks to the work of Christopher Reeve ( Figure below ), more research is being done on spinal cord injuries now than ever before. For example, scientists are trying to discover ways to regrow damaged spinal cord neurons. Q: What system is the spinal cord related to? A:
****
A:
nervous system
