Question: Answer the following question given this paragraph: Ecosystems require constant inputs of energy from sunlight or chemicals. Q: What do ecosystems require constant inputs of? A:
OPTIONS:
- Water
- fuel
- heating
- energy
Answer: energy

input with options: Answer the following question given this paragraph: Mitosis , or division of the nucleus, occurs only in eukaryotic cells. By the time mitosis occurs, the cell's DNA has already replicated. Mitosis occurs in four phases, called prophase, metaphase, anaphase, and telophase. You can see what happens in each phase in Figure below . The phases are described below. You can also learn more about the phases of mitosis by watching this video: https://www. youtube. com/watch?v=gwcwSZIfKlM . Q: Eukaryotic cells undergo what kinds of divisions that more primitive cells do not? A:
OPTIONS:
- budding
- meiosis
- homologous
- mitosis
output: mitosis

Q: Answer the following question given this paragraph: Science is a process of knowing about the natural universe through observation and experiment. Q: Science is a process of knowing about the natural universe through what two actions? A:

OPTIONS:
- thinking and guessing
- changes and experimentation
- guessing and observing
- observation and experimentation

A: observation and experimentation

input: OPTIONS:
- life cycle
- soul cycle
- water cycle
- carbon cycle Now, answer this question: Answer the following question given this paragraph: Roundworms may be free-living or parasitic. Free-living worms are found mainly in freshwater habitats. Some live in soil. They generally feed on bacteria, fungi, protozoans, or decaying organic matter. By breaking down organic matter, they play an important role in the carbon cycle. Q: Roundworms feed on various things, one of them being decaying organic matter. doing this, they play an important role in what famous cycle? A:
A:
output: carbon cycle

Answer the following question given this paragraph: Development of Bone Ossification, or osteogenesis, is the process of bone formation by osteoblasts. Ossification is distinct from the process of calcification; whereas calcification takes place during the ossification of bones, it can also occur in other tissues. Ossification begins approximately six weeks after fertilization in an embryo. Before this time, the embryonic skeleton consists entirely of fibrous membranes and hyaline cartilage. The development of bone from fibrous membranes is called intramembranous ossification; development from hyaline cartilage is called endochondral ossification. Bone growth continues until approximately age 25. Bones can grow in thickness throughout life, but after age 25, ossification functions primarily in bone remodeling and repair. Q: What begins approximately six weeks after fertilization in an embryo? A:

OPTIONS:
- calcification
- elongation
- incubation
- ossification

Answer: ossification

Q: Answer the following question given this paragraph: Pancreatic Secretion Regulation of pancreatic secretion is the job of hormones and the parasympathetic nervous system. The entry of acidic chyme into the duodenum stimulates the release of secretin, which in turn causes the duct cells to release bicarbonaterich pancreatic juice. The presence of proteins and fats in the duodenum stimulates the secretion of CCK, which then stimulates the acini to secrete enzyme-rich pancreatic juice and enhances the activity of secretin. Parasympathetic regulation occurs mainly during the cephalic and gastric phases of gastric secretion, when vagal stimulation prompts the secretion of pancreatic juice. Usually, the pancreas secretes just enough bicarbonate to counterbalance the amount of HCl produced in the stomach. Hydrogen ions enter the blood when bicarbonate is secreted by the pancreas. Thus, the acidic blood draining from the pancreas neutralizes the alkaline blood draining from the stomach, maintaining the pH of the venous blood that flows to the liver. Q: The entry of acidic chyme into the duodenum stimulates the release of what? A:

OPTIONS:
- progesterone
- gastrin
- oxygen
- secretin

A:
secretin
