Answer the following question given this paragraph: Scientists classify living things to make sense of biodiversity and who how living things are related. The science of classifying living things is called taxonomy. Q: What is the science of classifying living things is called? A:

OPTIONS:
- entomology
- methodology
- physiology
- taxonomy

Answer: taxonomy

Problem: OPTIONS:
- digestion
- hormones
- lymph system
- immune
Q: Answer the following question given this paragraph: The immune system protects the body from worms, germs, and other agents of harm. The immune system is like a medieval castle. The outside of the castle was protected by a moat and high stone walls. Inside the castle, soldiers were ready to fight off any invaders that managed to get through the outer defenses. Like a medieval castle, the immune system has a series of defenses. In fact, it has three lines of defense. Only pathogens that are able to get through all three lines of defense can harm the body. Q: What system protects the body from worms, germs, and other agents of harm? A:
Answer: immune

Problem:OPTIONS:
- Ionic
- deformation
- corrosion
- covalent

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? A:
****
A: covalent

Answer the following question given this paragraph: The Sun is Earth's main source of energy. The Sun gives us both light and heat. The Sun changes hydrogen into helium through nuclear fusion. This releases huge amounts of energy. The energy travels to the Earth mostly as visible light. The energy is carried through the empty space by radiation . We can use sunlight as an energy resource, called solar energy ( Figure above ). Q: What is earth's main source of energy? A:
OPTIONS:
- the atmosphere
- the moon
- the core
- the sun
the sun

Answer the following question given this paragraph: The diagrams above can serve as a pathway to understanding evolutionary history. The pathway can be traced from the origin of life to any individual species by navigating through the evolutionary branches between the two points. Also, by starting with a single species and tracing back towards the "trunk" of the tree, one can discover that species' ancestors, as well as where lineages share a common ancestry. In addition, the tree can be used to study entire groups of organisms. Another point to mention on phylogenetic tree structure is that rotation at branch points does not change the information. For example, if a branch point was rotated and the taxon order changed, this would not alter the information because the evolution of each taxon from the branch point was independent of the other. Many disciplines within the study of biology contribute to understanding how past and present life evolved over time; these disciplines together contribute to building, updating, and maintaining the "tree of life. " Information is used to organize and classify organisms based on evolutionary relationships in a scientific field called systematics. Data may be collected from fossils, from studying the structure of body parts or molecules used by an organism, and by DNA analysis. By combining data from many sources, scientists can put together the phylogeny of an organism; since phylogenetic trees are hypotheses, they will continue to change as new types of life are discovered and new information is learned. Q: Many disciplines within the study of biology contribute to understanding how past and present life evolved over time; these disciplines together contribute to building, updating, and maintaining this? A:
OPTIONS:
- amount of life
- root of life
- forests of life
- tree of life

Answer: tree of life
