Q: Answer the following question given this paragraph: Not all climate regions develop soils. Arid regions are poor at soil development. Not all regions develop the same soil horizons. Some areas develop as many as five or six distinct layers. Others develop only a few. Q: While some climate regions have multiple layers, arid regions are poor for development of what? A:

OPTIONS:
- rain
- plants
- minerals
- soil

A: soil

input: OPTIONS:
- avalanche
- sediment
- dirt bath
- mudflow Now, answer this question: Answer the following question given this paragraph: A mudflow is the sudden flow of mud down a slope because of gravity. Mudflows occur where the soil is mostly clay. Like landslides, mudflows usually occur when the soil is wet. Wet clay forms very slippery mud that slides easily. Mudflows follow river channels, washing out bridges, trees, and homes that are in their path. Q: What's it called when there's a sudden flow of mud? A:
A:
output: mudflow

Answer the following question given this paragraph: The ovaries release the eggs and secrete estrogen. Q: Which organ secretes estrogen? A:

OPTIONS:
- the testes
- the thyroid
- the kidney
- the ovaries

Answer: the ovaries

Problem: OPTIONS:
- steiner mendel
- charles darwin
- aristotle
- gregor mendel
Q: Answer the following question given this paragraph: Gregor Mendel was born in 1822 and grew up on his parents' farm in Austria. He did well in school and became a monk. He also went to the University of Vienna, where he studied science and math. His professors encouraged him to learn science through experimentation and to use math to make sense of his results. Mendel is best known for his experiments with the pea plant Pisum sativum (see Figure below ). You can watch a video about Mendel and his research at the following link: http://www. metacafe. com/watch/hl-19246625/milestones_in_science_engineering_gregor_mendel_and_classical_genetics/ . Q: What scientist and monk is best known for his experiments with pea plants? A:
Answer: gregor mendel

Problem:OPTIONS:
- wetlands
- tropics
- meadows
- peatlands

Answer the following question given this paragraph: Q: What are boggy regions with thick layers of peat called? A:
****
A: peatlands

Problem:OPTIONS:
- inhibited hormone
- tharayroid hormone
- elevated hormone
- parathyroid hormone

Answer the following question given this paragraph: Hyperparathyroidism results from an overproduction of parathyroid hormone. This results in excessive calcium being removed from bones and introduced into blood circulation, producing structural weakness of the bones, which can lead to deformation and fractures, plus nervous system impairment due to high blood calcium levels. Hypoparathyroidism, the underproduction of PTH, results in extremely low levels of blood calcium, which causes impaired muscle function and may result in tetany (severe sustained muscle contraction). The hormone calcitonin, which is produced by the parafollicular or C cells of the thyroid, has the opposite effect on blood calcium levels as does PTH. Calcitonin decreases blood calcium levels by inhibiting osteoclasts, stimulating osteoblasts, and stimulating calcium excretion by the kidneys. This results in calcium being added to the bones to promote structural integrity. Calcitonin is most important in children (when it stimulates bone growth), during pregnancy (when it reduces maternal bone loss), and during prolonged starvation (because it reduces bone mass loss). In healthy nonpregnant, unstarved adults, the role of calcitonin is unclear. Q: Hyperparathyroidism results from an overproduction of what? A:
****
A:
parathyroid hormone
