Answer the following question given this paragraph: Oceans are the major source of water vapor in the atmosphere. Sunlight heats water near the sea surface ( Figure below ). As the water warms, some of it evaporates. The water vapor rises into the air, where it may form clouds and precipitation. Precipitation provides the freshwater needed by plants and other living things. Q: What is the major source of water vapor in the atmosphere? Choices: - drift - sea - streams - ocean A:
ocean
Answer the following question given this paragraph: Dalton's theory was soon widely accepted. Most of it is still accepted today. The only part that is no longer accepted is his idea that atoms are the smallest particles. Scientists now know that atoms consist of even smaller particles. Q: What was once believed to be the smallest of all particles, as dalton's theory proposed? Choices: - nucleus - molecule - neutron - atom A:
atom
Q: Answer the following question given this paragraph: A heart block refers to an interruption in the normal conduction pathway. The nomenclature for these is very straightforward. SA nodal blocks occur within the SA node. AV nodal blocks occur within the AV node. Infra-Hisian blocks involve the bundle of His. Bundle branch blocks occur within either the left or right atrioventricular bundle branches. Q: What do we call an interruption in the normal conduction pathway of the heart? Choices: - heart attack - infarction - heartburn - heart block A:
A: heart block
Question: Answer the following question given this paragraph: Toward the late stages of pregnancy, a drop in progesterone and stretching forces from the fetus lead to increasing uterine irritability and prompt labor. Contractions serve to dilate the cervix and expel the newborn. Delivery of the placenta and associated fetal membranes follows. Q: Toward the late stages of pregnancy, a drop in progesterone and stretching forces from the fetus lead to increasing uterine irritability and prompt labor. contractions serve to dilate the cervix and expel this? Choices: - blood - tissues - uteris - newborn A:
Answer: newborn

Answer the following question given this paragraph: Almost anything can happen with the weather. Climate, however, is more predictable. Climate is the long-term average of weather in a particular spot. Good climate is why we choose to vacation in Hawaii in February (usually on the leeward side). Of course, the weather is not guaranteed to be good! A location's climate considers the same characteristics as its weather. These are its air temperature, humidity, wind speed and direction, and the type, quantity, and frequency of precipitation. For climate, these things are averaged over time. Q: What is the long-term average of weather in a particular spot called? Choices: - weather - migration - temperature - climate A:
**Answer**
climate
Q: Answer the following question given this paragraph: The degree of DNA coiling determines whether the chromosome strands are short and thick or long and thin. Between cell divisions, the DNA in chromosomes is more loosely coiled and forms long thin strands called chromatin . DNA is in this uncoiled form during the majority of the cell cycle, making the DNA available to the proteins involved in DNA replication and transcription. Before the cell divides, the chromatin coils up more tightly and form chromosomes. Only chromosomes stain clearly enough to be seen under a microscope. The word chromosome comes from the Greek word chroma (color), and soma (body) due to its ability to be stained strongly by dyes. Q: What determines the length and thickness of dna chromosomes? Choices: - degree of rna coiling - type of dna - number of chromosomes - degree of dna coiling A:
A: degree of dna coiling
