input with options: Answer the following question given this paragraph: After cells differentiate, all the major organs begin to form during the remaining weeks of embryonic development. A few of the developments that occur in the embryo during weeks 4 through 8 are listed in Figure below . As the embryo develops, it also grows in size. By the eighth week of development, the embryo is about 30 millimeters (just over 1 inch) in length. It may also have begun to move. Q: During which stage of development do all the major organs begin to form? A:
OPTIONS:
- third trimester
- nascent
- transgenic
- embryonic
output: embryonic

Q: Answer the following question given this paragraph: Figure 23.28 Digestion and Absorption Digestion begins in the mouth and continues as food travels through the small intestine. Most absorption occurs in the small intestine. Q: Where does digestion begin? A:

OPTIONS:
- esophogus
- tongue
- stomach
- mouth

A: mouth

input: OPTIONS:
- hydrophobic
- dendritic
- Golgi apparatus
- synaptic Now, answer this question: Answer the following question given this paragraph: Secretory Vesicles contain materials that are to be excreted from the cell, such as wastes or hormones . Secretory vesicles include synaptic vesicles and vesicles in endocrine tissues. Synaptic vesicles store neurotransmitters. They are located at presynaptic terminals in neurons. When a signal reaches the end of an axon, the synaptic vesicles fuse with the cell membrane and release the neurotransmitter. The neurotransmitter crosses the synaptic junction, and binds to a receptor on the next cell. Some cells also produce molecules, such as hormones produced by endocrine tissues, needed by other cells. These molecules are stored in secretory vesicles and released when needed. Secretory vesicles also hold enzymes needed to make extracellular structures, such as the extracellular matrix of animal cells. Q: What vesicles store neurotransmitters? A:
A:
output: synaptic

Answer the following question given this paragraph: In eukaryotic cells, most of the intracellular proteins that are activated by a ligand binding to a receptor protein are enzymes. Receptor proteins are named after the type of enzyme that they interact with inside the cell. These enzymes include G proteins and protein kinases, likewise there are G-protein-linked receptors and tyrosine kinase receptors. A kinase is a protein involved in phosphorylation. Tyrosine kinase receptors bind many polypeptide growth factors, cytokines, and hormones. Once the ligand is bound, these receptors specifically phosphorylate tyrosine amino acids, activating the signal transduction process inside the cell. Q: What is named after the type of enzyme they interact with in the cell? A:

OPTIONS:
- oxygen proteins
- function proteins
- nitrogen proteins
- receptor proteins

Answer: receptor proteins

Problem: OPTIONS:
- migration
- evolution
- immigration
- erosion
Q: Answer the following question given this paragraph: As pictured below ( Figure below ), some grazing animals, especially sheep and goats, eat grass right down to the roots. They may even pull the grass entirely out of the ground. Grazing animals can kill the grass. They may thin it out so much that it offers little protection to the soil. If animals are kept in the same place too long, the soil may become completely bare. The bare soil is easily eroded by wind and water. Q: By pulling out grass by its roots and over-grazing, livestock contribute to what negative process? A:
Answer: erosion

Answer the following question given this paragraph: Cleavage is the tendency of a mineral to break along certain planes. When a mineral breaks along a plane, it makes a smooth surface. Minerals with different crystal structures will break or cleave in different ways ( Figure below ). Halite tends to form cubes with smooth surfaces. Mica tends to form sheets. Fluorite can form octahedrons. Q: What term is used to describe the tendency of a mineral to break along certain planes? A:

OPTIONS:
- tooth decay
- porosis
- erosion
- cleavage

Answer:
cleavage
