input with options: Answer the following question given this paragraph: 10.3 Control of the Cell Cycle Each step of the cell cycle is monitored by internal controls called checkpoints. There are three major checkpoints in the cell cycle: one near the end of G1, a second at the G2/M transition, and the third during metaphase. Positive regulator molecules allow the cell cycle to advance to the next stage. Negative regulator molecules monitor cellular conditions and can halt the cycle until specific requirements are met. Q: In a cell cycle, what kind of regulator molecules allow advancement to the next stage? A:
OPTIONS:
- strong
- similar
- negative
- positive
output: positive

Q: Answer the following question given this paragraph: Q: What are compounds with the same molecular formula but different structures and properties called? A:

OPTIONS:
- substrates
- monomers
- polymers
- isomers

A: isomers

input: OPTIONS:
- transport vessels
- capillaries
- dna vesicles
- transport vesicles Now, answer this question: Answer the following question given this paragraph: Transport vesicles are able to move molecules between locations inside the cell. For example, transport vesicles move proteins from the rough endoplasmic reticulum to the Golgi apparatus. Q: What cellular structure moves molecules between locations inside the cell? A:
A:
output: transport vesicles

Answer the following question given this paragraph: Q: Furthermore, most of the proteins within membranes have both hydrophobic and which other regions? A:

OPTIONS:
- atmospheric
- lymphatic
- cytosolic
- hydrophilic

Answer: hydrophilic

Problem: OPTIONS:
- nucleus
- cytoplasm
- cell wall
- blastocyst
Q: Answer the following question given this paragraph: Blastocyst. The blastocyst consists of an outer layer of cells called the trophoblast and an inner cell mass called the embryoblast. The blastocyst fluid-filled cavity is also known as the blastocoel or blastocoele. Q: What structure consists of an outer layer of cells called the trophoblast and an inner cell mass called the embryoblast? A:
Answer: blastocyst

Answer the following question given this paragraph: All chemical reactions, even exothermic reactions, need activation energy to get started. Activation energy is needed to bring reactants together so they can react. Q: What do all chemical reactions need to get started? A:

OPTIONS:
- expression energy
- kinetic energy
- potential energy
- activation energy

Answer:
activation energy
