input with options: 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
output: ossification

Q: Answer the following question given this paragraph: A liquid is a form of matter that has a definite volume, but an indefinite shape. As water is poured from one container into another, it adopts the shape of its new container. However, the volume of the water does not change, because the water molecules are still relatively close to one another in the liquid state. Unlike a solid, the arrangement of particles in a liquid is not rigid and orderly. Liquids are also incompressible. Q: What is a form of matter that has a definite volume, but an indefinite shape? A:

OPTIONS:
- a solid
- a plasma
- a gas
- a liquid

A: a liquid

input: OPTIONS:
- spirogyra
- invertebrates
- xerophyte
- cephalochordata Now, answer this question: Answer the following question given this paragraph: Living species of chordates are classified into three major subphyla: Vertebrata, Urochordata, and Cephalochordata. Vertebrates are all chordates that have a backbone. The other two subphyla are invertebrate chordates that lack a backbone. Q: Living species of chordates are classified into three major subphyla: vertebrata, urochordata, and what? A:
A:
output: cephalochordata

Answer the following question given this paragraph: The cytoskeleton provides the shape of the cell. Q: What provides the shape of a cell? A:

OPTIONS:
- nucleus
- cytoplasm
- cellulose
- cytoskeleton

Answer: cytoskeleton

Problem: OPTIONS:
- Lactose
- pesticides
- cancers
- vaccines
Q: Answer the following question given this paragraph: Many viral diseases can be prevented by giving people vaccines (see Figure below ). A vaccine is a substance that contains pathogens such as viruses. The pathogens have been changed in some way so they no longer cause disease. However, they can still provoke a response from the host's immune system. This results in immunity, or the ability to resist the pathogen. Vaccines have been produced for the viruses that cause measles, chicken pox, mumps, polio, and several other diseases. Q: Many viral diseases can be prevented by giving people what? A:
Answer: vaccines

Answer the following question given this paragraph: Living chordates are mainly vertebrates. In vertebrates, the notochord develops into a backbone, or vertebral column, after the embryonic stage. A small percentage of chordates are invertebrates. Their notochord never develops into a backbone. Invertebrate chordates include tunicates and lancelets. Both groups of animals are small and relatively primitive. They are probably similar to the earliest chordates that evolved more than 500 million years ago. Q: During the embryonic stage of vertebrates, the notochord develops into what? A:

OPTIONS:
- rib cage
- umbilical cord
- brain stem
- backbone

Answer:
backbone
