Q: Answer the following question given this paragraph: Calcium hydroxide and calcium carbonate are effective in neutralizing the effects of acid rain on lakes. Suggest other compounds that might be effective in treating lakes. Give a plausible reason to explain why Ca(OH)2 and CaCO3 are used. ♦️ Approximately 95% of the chlorine produced industrially comes from the electrolysis of sodium chloride solutions (brine): NaCl(aq) + H2O(l) Cl2(g) + H2(g) + NaOH(aq) Chlorine is a respiratory irritant whose presence is easily detected by its penetrating odor and greenishyellow color. One use for the chlorine produced is in the manufacture of hydrochloric acid. Q: Calcium hydroxide and calcium carbonate are effective in neutralizing the effects of what on lakes? A:
Answer: acid rain

Problem:OPTIONS:
- rayon
- styrofoam
- silicon
- rubber

Answer the following question given this paragraph: Polyisoprene is a polymer of isoprene and is better known as rubber. It is produced naturally by rubber trees, but several variants have been developed which demonstrate improvements on the properties of natural rubber. Q: What is polyisoprene better known as? A:
****
A: rubber

Answer the following question given this paragraph: Before the atmosphere became oxygenated, the planet was subjected to strong radiation; thus, the first organisms would have flourished where they were more protected, such as in ocean depths or beneath the surface of Earth. At this time, too, strong volcanic activity was common on Earth, so it is likely that these first organismsthe first prokaryoteswere adapted to very high temperatures. These are not the typical temperate environments in which most life flourishes today; thus, we can conclude that the first organisms that appeared on Earth likely were able to withstand harsh conditions. Microbial mats may represent the earliest forms of life on Earth, and there is fossil evidence of their presence, starting about 3.5 billion years ago. A microbial mat is a large biofilm, a multi-layered sheet of prokaryotes (Figure 13.3a), including mostly bacteria, but also archaea. Microbial mats are a few centimeters thick, and they typically grow on moist surfaces. Their various types of prokaryotes carry out different metabolic pathways, and for this reason, they reflect various colors. Prokaryotes in a microbial mat are held together by a gummy-like substance that they secrete. The first microbial mats likely obtained their energy from hydrothermal vents. A hydrothermal vent is a fissure in Earth's surface that releases geothermally heated water. With the evolution of photosynthesis about 3 billion years ago, some prokaryotes in microbial mats came to use a more widely available energy sourcesunlightwhereas others were still dependent on chemicals from hydrothermal vents for food. Q: Before the atmosphere became oxygenated, the planet was subjected to what harmful energy source, meaning the first organisms would have flourished where they were more protected? A:
OPTIONS:
- evaporation
- conduction
- convection
- radiation
radiation

Answer the following question given this paragraph: Bacteria are the most abundant living things on Earth. They live in almost all environments. They are found in the air, ocean, soil, and intestines of animals. They are even found in rocks deep below Earth's surface. Any surface that has not been sterilized is likely to be covered with bacteria. The total number of bacteria in the world is amazing. It's estimated to be about 5 million trillion trillion. If you write that number in digits, it has 30 zeroes!. Q: What is the most abundant living thing on earth that can be found in almost any environment? A:
OPTIONS:
- pests
- viruses
- pathogens
- bacteria

Answer: bacteria

Question: Answer the following question given this paragraph: Q: What serves to replace nonreproducing specialized cells as needed in the adult body? A:
OPTIONS:
- osteoclast cells
- monocyte cells
- dendritic cells
- stem cells
Answer: stem cells

input: OPTIONS:
- hypothesis
- theory
- notion
- principle Now, answer this question: Answer the following question given this paragraph: The word principle can be defined as "a fundamental truth or proposition that serves as the foundation for a system of belief or behavior or for a chain of reasoning. " A principle of biology is a fundamental concept that is just as true for a bee or a sunflower as it is for us. All life, including that sunflower and bee, is made of at least one cell. The traits of a particular organism are embedded within its genes, that organism must maintain homeostasis to survive, and that organism has evolved from previously existing species. Q: A _______ of biology is a fundamental concept that is just as true for a bee or a sunflower as it is for us. A:
A:
output:
principle
