Answer the following question given this paragraph: The weather map pictured below ( Figure above ) shows air pressure. The lines on the map connect places that have the same air pressure. Air pressure is measured in a unit called the millibar. Isobars are the lines that connect the points with the same air pressure. The map also shows low- and high-pressure centers and fronts. Find the cold front on the map. This cold front is likely to move toward the northeast over the next couple of days. How could you use this information to predict what the weather will be on the East Coast?. Q: What is the unit used to measure air pressure? Choices: - pounds per inch - newtons - mass - millibar A:
(Answer)
millibar
Ques: Answer the following question given this paragraph: Without weathering, we would not have any soil on Earth. People could not live on Earth without soil! Your life and the lives of most organisms depend on soil. Soil is only a very thin layer over solid rock. Yet, it is the place where reactions between solid rock, liquid water and air take place. We get wood, paper, cotton, medicines, and even pure water from soil. So soil is a very important resource. Our precious soil needs to be carefully managed and cared for. If we don't take care of the soil we have, we may not be able to use it in the future. Q: Weathering is fundamental to the creation of what, which exists as a very thin layer over solid rock? Choices: - fungus - moss - aquifers - soil A:
Ans: soil

Ques:Answer the following question given this paragraph: Illustration of the two types of vesicle transport, exocytosis and endocytosis. Endocytosis and exocytosis are types of vesicle transport that carry very large molecules across the cell membrane. Q: Endocytosis and exocytosis are types of vesicle transport that carry very large molecules across what structure? Choices: - cell substrate - the heart - dermis - cell membrane A:

Ans:cell membrane
Answer the following question given this paragraph: 19.2 Population Genetics Both genetic and environmental factors can cause phenotypic variation in a population. Different alleles can confer different phenotypes, and different environments can also cause individuals to look or act differently. Only those differences encoded in an individual's genes, however, can be passed to its offspring and, thus, be a target of natural selection. Natural selection works by selecting for alleles that confer beneficial traits or behaviors, while selecting against those for deleterious qualities. Genetic drift stems from the chance occurrence that some individuals in the germ line have more offspring than others. When individuals leave or join the population, allele frequencies can change as a result of gene flow. Mutations to an individual's DNA may introduce new variation into a population. Allele frequencies can also be altered when individuals do not randomly mate with others in the group. Q: What works by selecting for alleles that confer beneficial traits or behaviors, while selecting against those for deleterious qualities? Choices: - same selection - artificial selection - characteristic selection - natural selection A:
natural selection
