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? Choices: - icelandic and aquatic - aquatic and galactic - terrestrial and galactic - terrestrial and aquatic A:
(Answer)
terrestrial and aquatic
Ques: Answer the following question given this paragraph: Curiosity, the rover, has found evidence of a flowing stream on Mars. Layers of smooth, water-polished pebbles have been photographed. This is exactly what you would see in a stream on Earth. There are many surface features that look like water-eroded canyons. Since there was liquid water on Mars, scientists think that life might have existed there in the past. One of Curiosity's tasks is to sample the soil to search for carbon and other evidence of life. Q: Evidence for the presence of what on mars makes scientists think that life might have existed there in the past? Choices: - gas - plasma - air - water A:
Ans: water
(Q).
Answer the following question given this paragraph: Antibodies also mark pathogens for destruction by phagocytic cells, such as macrophages or neutrophils, because phagocytic cells are highly attracted to macromolecules complexed with antibodies. Phagocytic enhancement by antibodies is called opsonization. In a process called complement fixation, IgM and IgG in serum bind to antigens and provide docking sites onto which sequential complement proteins can bind. The combination of antibodies and complement enhances opsonization even further and promotes rapid clearing of pathogens. Affinity, Avidity, and Cross Reactivity Not all antibodies bind with the same strength, specificity, and stability. In fact, antibodies exhibit different affinities (attraction) depending on the molecular complementarity between antigen and antibody molecules, as illustrated in Figure 42.25. An antibody with a higher affinity for a particular antigen would bind more strongly and stably, and thus would be expected to present a more challenging defense against the pathogen corresponding to the specific antigen. Q: Antibodies also mark pathogens for destruction by which cells? Choices: - interferons - leukocytes - platelets - phagocytic A:
(A).
phagocytic
Ques:Answer the following question given this paragraph: Amphibians may attract mates with calls or scents. Q: Amphibians may attract mates with what? Choices: - only calls - only scents - neither - calls or scents A:

Ans:calls or scents
Question: Answer the following question given this paragraph: Any unused energy in food, whether it comes from carbohydrates, proteins, or lipids, is stored in the body as fat. An extra 3,500 Calories of energy results in the storage of almost half a kilogram (1 pound) of stored body fat. People who consistently consume more food energy then they need may become obese. Obesity occurs when the body mass index is 30.0 kg/m 2 or greater. Body mass index (BMI) is an estimate of the fat content of the body. It is calculated by dividing a person's weight (in kilograms) by the square of the person's height (in meters). Obesity increases the risk of health problems such as type 2 diabetes and hypertension. Q: Any unused energy in food, whether it comes from carbohydrates, proteins, or lipids, is stored in the body where? Choices: - kidneys - spleen - bones - fat A:
Answer:
fat
