Q: Answer the following question given this paragraph: Carbon sequestration captures carbon dioxide as it is emitted by a power plant before it enters the atmosphere. The carbon dioxide is then stored in another form. Carbon is sequestered naturally by forests. Trees take in carbon dioxide for photosynthesis. Artificial methods of sequestering carbon underground are being researched. This is just one of the geoengineering methods that are being researched for reducing carbon dioxide. Q: What captures carbon dioxide as it is emitted by a power plant before it enters the atmosphere? A:

OPTIONS:
- chemical sequestration
- oxide sequestration
- nitrogen sequestration
- carbon sequestration

A: carbon sequestration

input: OPTIONS:
- bicellular sphincters
- diocesan sphincters
- cell membrane
- precapillary sphincters Now, answer this question: Answer the following question given this paragraph: Q: What regulates the passage of blood into capillary beds? A:
A:
output: precapillary sphincters

Answer the following question given this paragraph: Some volcanoes form over active hot spots . Scientists count about 50 hot spots on the Earth. Hot spots may be in the middle of a tectonic plate. Hot spots lie directly above a column of hot rock called a mantle plume . Mantle plumes continuously bring magma up from the mantle towards the crust ( Figure below ). Q: What substance comes toward earth's crust through mantle plumes? A:

OPTIONS:
- rocks
- water
- gas
- magma

Answer: magma

Problem: OPTIONS:
- change and energy
- energy and motion
- force and matter
- matter and energy
Q: Answer the following question given this paragraph: Matter and energy are the most basic concepts in physical science. Watch this video about matter and energy, and then answer the questions below. Q: What are considered to be the most basic concepts in the field of physical science? A:
Answer: matter and energy

Problem:OPTIONS:
- nonvascular
- deciduous
- perennial
- vascular

Answer the following question given this paragraph: Unlike nonvascular plants, all vascular plantsincluding seedless vascular plantshave a dominant sporophyte generation. Seedless vascular plants include clubmosses and ferns. Figure below shows a typical fern life cycle. Q: Do nonvascular or vascular plants have a dominant sporophyte generation? A:
****
A: vascular

Problem:OPTIONS:
- purification
- sterilization
- osmosis
- process of desalinization

Answer the following question given this paragraph: Fresh water is essential for good crops. In some areas of the world, there is enough rain to accomplish this task. In other locales, water must be provided so the crops will grow. Worldwide, irrigation covers about 18% of farm land and produces some 40% of crops. A major source of cleaner water in many parts of the world is provided by the process of desalinization . Q: Which process helps provide cleaner water for agriculture? A:
****
A:
process of desalinization
