Q: Answer the following question given this paragraph: Some life scientists mainly do lab research. Other life scientists, like the botanist in Figure below , work in natural settings. This is called fieldwork . Whether in the lab or the field, research in life science can be dangerous. It's important to be aware of the risks and how to stay safe. Q: When scientists work in natural settings rather than a lab, it is called what? A:
Answer: fieldwork

Answer the following question given this paragraph: Reptiles are a class of ectothermic, tetrapod vertebrates. They have several adaptations for living on dry land, such as tough keratin scales and efficient lungs for breathing air. They also have a three-chambered heart and relatively well-developed brain. Q: How many chambers are in a reptiles heart? A:
****
A: three

Answer the following question given this paragraph: 44.3 | Terrestrial Biomes By the end of this section, you will be able to: Identify the two major abiotic factors that determine terrestrial biomes Recognize distinguishing characteristics of each of the eight major terrestrial biomes The Earth's biomes are categorized into two major groups: terrestrial and aquatic. Terrestrial biomes are based on land, while aquatic biomes include both ocean and freshwater biomes. The eight major terrestrial biomes on Earth are each distinguished by characteristic temperatures and amount of precipitation. Comparing the annual totals of precipitation and fluctuations in precipitation from one biome to another provides clues as to the importance of abiotic factors in the distribution of biomes. Temperature variation on a daily and seasonal basis is also important for predicting the geographic distribution of the biome and the vegetation type in the biome. The distribution of these biomes shows that the same biome can occur in geographically distinct areas with similar climates (Figure 44.12). Q: The earth's biomes are categorized into two major groups named what? A:
OPTIONS:
- icelandic and aquatic
- aquatic and galactic
- terrestrial and galactic
- terrestrial and aquatic
terrestrial and aquatic

OPTIONS:
- urinary tract
- tissues tract
- physical tract
- digestive tract

Answer: digestive tract

Question: Answer the following question given this paragraph: Fog forms when there is a difference in temperature between the land and the air. Q: What forms when there is a difference in temperature between the land and the air? A:
OPTIONS:
- smoke
- tsunamis
- sandstorms
- fog
Answer: fog

input: OPTIONS:
- evaporation
- conduction
- convection
- radiation Now, answer this question: 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:
A:
output:
radiation
