Question: Answer the following question given this paragraph: the cell is the fundamental unit of structure and function in all living organisms,. Q: What is the fundamental unit of structure and function in all living organisms? A:
OPTIONS:
- the spinal cord
- the backbone
- the vessels
- the cell
Answer: the cell

input with options: Answer the following question given this paragraph: You've probably noticed dew on the grass on a summer morning. Why does dew form? Remember that the land heats up and cools down fairly readily. So when night comes, the land cools. Air that was warm and humid in the daytime also cools over night. As the air cools, it can hold less water vapor. Some of the water vapor condenses on the cool surfaces, such as blades of grass. The temperature at which water vapor condenses is called the dew point . If this temperature is below freezing, ice crystals of frost form instead of dew ( Figure below ). The dew point occurs at 100 percent relative humidity. Can you explain why?. Q: What is the name of the "point" that refers to the temperature at which water vapor condenses? A:
OPTIONS:
- melting point
- brine point
- water point
- dew point
output: dew point

Q: Answer the following question given this paragraph: Chemical reactions follow the laws of thermodynamics. Q: Chemical reactions follow the laws of what? A:

OPTIONS:
- Newton
- quantum physics
- photosynthesis
- thermodynamics

A: thermodynamics

input: OPTIONS:
- pulses
- proteins
- information
- signals Now, answer this question: Answer the following question given this paragraph: Nerve Impulse Transmission within a Neuron For the nervous system to function, neurons must be able to send and receive signals. These signals are possible because each neuron has a charged cellular membrane (a voltage difference between the inside and the outside), and the charge of this membrane can change in response to neurotransmitter molecules released from other neurons and environmental stimuli. To understand how neurons communicate, one must first understand the basis of the baseline or 'resting' membrane charge. Neuronal Charged Membranes The lipid bilayer membrane that surrounds a neuron is impermeable to charged molecules or ions. To enter or exit the neuron, ions must pass through special proteins called ion channels that span the membrane. Ion channels have different configurations: open, closed, and inactive, as illustrated in Figure 35.9. Some ion channels need to be activated in order to open and allow ions to pass into or out of the cell. These ion channels are sensitive to the environment and can change their shape accordingly. Ion channels that change their structure in response to voltage changes are called voltage-gated ion channels. Voltage-gated ion channels regulate the relative concentrations of different ions inside and outside the cell. The difference in total charge between the inside and outside of the cell is called the membrane potential. Q: For the nervous system to function, neurons must be able to send and receive what? A:
A:
output: signals

Question: Answer the following question given this paragraph: Molecular geometry is the three-dimensional arrangement of atoms in a molecule. The molecular geometry, or shape, of a molecule is an important factor that affects the physical and chemical properties of a compound. Those properties include melting and boiling points, solubility, density, and the types of chemical reactions that a compound undergoes. In this lesson, you will learn a technique to predict molecular geometry based on a molecule's Lewis electron dot structure. Q: Molecular geometry is the three-dimensional arrangement of atoms in a what? A:
OPTIONS:
- genes
- DNA
- nucleus
- molecule
Answer:
molecule
