Answer the following question given this paragraph: Proteins have different shapes and molecular weights; some proteins are globular in shape whereas others are fibrous in nature. For example, hemoglobin is a globular protein, but collagen, found in our skin, is a fibrous protein. Protein shape is critical to its function, and this shape is maintained by many different types of chemical bonds. Changes in temperature, pH, and exposure to chemicals may lead to permanent changes in the shape of the protein, leading to loss of function, known as denaturation. All proteins are made up of different arrangements of the same 20 types of amino acids. Q: Changes in temperature, ph, and exposure to chemicals may lead to permanent changes in the shape of a protein, leading to loss of function known as what? Choices: - digestion - fermentation - bioturbation - denaturation A:
denaturation
Answer the following question given this paragraph: The continent of Antarctica is covered with an ice cap. Q: Which continent is covered with an ice cap? Choices: - asia - greenland - australia - antarctica A:
antarctica
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? Choices: - chemical sequestration - oxide sequestration - nitrogen sequestration - carbon sequestration A:
A: carbon sequestration
Question: Answer the following question given this paragraph: Q: What regulates the passage of blood into capillary beds? Choices: - bicellular sphincters - diocesan sphincters - cell membrane - precapillary sphincters A:
Answer: 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? Choices: - rocks - water - gas - magma A:
**Answer**
magma
