Q: Answer the following question given this paragraph: Figure 12.25 Graded Potentials Graded potentials are temporary changes in the membrane voltage, the characteristics of which depend on the size of the stimulus. Some types of stimuli cause depolarization of the membrane, whereas others cause hyperpolarization. It depends on the specific ion channels that are activated in the cell membrane. Q: Graded potentials are temporary changes in what, the characteristics of which depend on the size of the stimuli? A:

OPTIONS:
- components voltage
- organic voltage
- organism voltage
- membrane voltage

A: membrane voltage

input: OPTIONS:
- glucose
- proton
- nuclei
- mitochondria Now, answer this question: Answer the following question given this paragraph: Cellular respiration occurs in the mitochondria. Figure 20.13 "Respiration" shows the mitochondrion's two membranes: outer andinner. The inner membrane is extensively folded into a series of internal ridges calledcristae. Thus there are two compartments in mitochondria: the intermembrane space, which lies between the membranes, and the matrix, which lies inside the inner membrane. Q: What part of the cell does cellular respiration occur? A:
A:
output: mitochondria

Answer the following question given this paragraph: Q: How long does it take for the earth to make a complete rotation of its axis? A:

OPTIONS:
- one year
- one month
- 24.25 hours
- 24 hours

Answer: 24 hours

Problem: OPTIONS:
- big plate
- abnormal plate
- magnetic plate
- horizontal plate
Q: Answer the following question given this paragraph: Palatine Bone The palatine bone is one of a pair of irregularly shaped bones that contribute small areas to the lateral walls of the nasal cavity and the medial wall of each orbit. The largest region of each of the palatine bone is the horizontal plate. The plates from the right and left palatine bones join together at the midline to form the posterior quarter of the hard palate (see Figure 7.8a). Thus, the palatine bones are best seen in an inferior view of the skull and hard palate. Q: The largest region of each of the palatine bone is the what? A:
Answer: horizontal plate

Problem:OPTIONS:
- kinetic energy
- centrifugal force
- momentum
- gravity

Answer the following question given this paragraph: Q: What force pulls objects toward the center of the earth? A:
****
A: gravity

Problem:OPTIONS:
- variation
- evaluation
- evacuation
- observation

Answer the following question given this paragraph: Science rests on evidence and logic, so it deals only with things that can be observed. An observation is anything that is detected either through human senses or with instruments and measuring devices that extend human senses. Things that cannot be observed or measured by current meanssuch as supernatural beings or eventsare outside the bounds of science. Consider these two questions about life on Earth:. Q: What term means anything that is detected either through human senses or with instruments and measuring devices that extend human senses? A:
****
A:
observation
