Q: Answer the following question given this paragraph: 22.1 | Prokaryotic Diversity By the end of this section, you will be able to: Describe the evolutionary history of prokaryotes Discuss the distinguishing features of extremophiles Explain why it is difficult to culture prokaryotes Prokaryotes are ubiquitous. They cover every imaginable surface where there is sufficient moisture, and they live on and inside of other living things. In the typical human body, prokaryotic cells outnumber human body cells by about ten to one. They comprise the majority of living things in all ecosystems. Some prokaryotes thrive in environments that are inhospitable for most living things. Prokaryotes recycle nutrientsessential substances (such as carbon and nitrogen)and they drive the evolution of new ecosystems, some of which are natural and others man-made. Prokaryotes have been on Earth since long before multicellular life appeared. Q: What group of simple organisms recycles nutrients and has been on earth since long before multicellular life appeared? A:
Answer: prokaryotes

Problem:OPTIONS:
- antennae and pseudopod
- pseudopod and mantle
- radula and antennae
- mantle and radula

Answer the following question given this paragraph: Two unique features of mollusks are the mantle and radula (see Figure above ). The mantle is a layer of tissue that lies between the shell and the body. It secretes calcium carbonate to form the shell. It forms a cavity, called the mantle cavity , between the mantle and the body. The mantle cavity pumps water for filter feeding. The radula is a feeding organ with teeth made of chitin. It is located in front of the mouth in the head region. Herbivorous mollusks use the radula to scrape food such as algae off rocks. Predatory mollusks use the radula to drill holes in the shells of their prey. Q: What are the two unique features of mollusks? A:
****
A: mantle and radula

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
thermodynamics

Answer the following question given this paragraph: Without communication, animals would not be able to live together in groups. Animals that live in groups with other members of their species are called social animals. Social animals include many species of insects, birds, and mammals. Specific examples are ants, bees, crows, wolves, and human beings. Q: Animals that live in groups with other members of their species are called what? A:
OPTIONS:
- available animals
- grouping animals
- aggressive animals
- social animals

Answer: social animals

Question: Answer the following question given this paragraph: To the extent that behaviors are controlled by genes, they may evolve through natural selection. If behaviors increase fitness , they are likely to become more common over time. If they decrease fitness, they are likely to become less common. Q: To the extent that behaviors are controlled by what, they may evolve through natural selection? A:
OPTIONS:
- rna
- dna
- mutation
- genes
Answer: genes

input: OPTIONS:
- Water
- fuel
- food
- energy Now, answer this question: Answer the following question given this paragraph: This caterpillar is busily munching its way through leaf after leaf. In fact, caterpillars do little more than eat, day and night. Like all living things, they need food to provide their cells with energy. The caterpillar will soon go through an amazing transformation to become a beautiful butterfly. These changes require a lot of energy. Q: Transforming from a caterpillar to a butterfly requires a lot of what? A:
A:
output:
energy
