Q: Answer the following question given this paragraph: Air movement takes place in the troposphere. Air moves because of differences in heating. The differences create convection currents and winds. Q: What is the primary cause of air movement in the troposphere? A:

OPTIONS:
- solar winds
- asteroids
- the ozone layer
- differences in heating

A: differences in heating

input: OPTIONS:
- nose system signals
- skeletal system signals
- heart system signals
- nervous system signals Now, answer this question: Answer the following question given this paragraph: may be located in organs or tissues that have functions in addition to hormone production. Hormones circulate throughout the body and stimulate a response in cells that have receptors able to bind with them. The changes brought about in the receiving cells affect the functioning of the organ system to which they belong. Many of the hormones are secreted in response to signals from the nervous system, thus the two systems act in concert to effect changes in the body. Q: Many of the hormones are secreted in response to what signals of the body? A:
A:
output: nervous system signals

Answer the following question given this paragraph: Intermediate filaments have no role in cell movement. Their function is purely structural. They bear tension, thus maintaining the shape of the cell, and anchor the nucleus and other organelles in place. Figure 4.22 shows how intermediate filaments create a supportive scaffolding inside the cell. The intermediate filaments are the most diverse group of cytoskeletal elements. Several types of fibrous proteins are found in the intermediate filaments. You are probably most familiar with keratin, the fibrous protein that strengthens your hair, nails, and the epidermis of the skin. Q: What is the most familiar fibrous protein found in your body? A:

OPTIONS:
- cellulose
- Actin
- Collagen
- keratin

Answer: keratin

Problem: OPTIONS:
- nest
- tree
- gullet
- crop
Q: Answer the following question given this paragraph: Birds have a sac-like structure called a crop to store and moisten food that is waiting to be digested. They also have an organ called a gizzard that contains swallowed stones. The stones make up for the lack of teeth by grinding food, which can then be digested more quickly. Both structures make it easier for the digestive system to produce a steady supply of nutrients from food. Q: Where do birds store and moisten food that is waiting to be digested? A:
Answer: crop

Problem:OPTIONS:
- cell tube
- occular tube
- peripheral tube
- neural tube

Answer the following question given this paragraph: called growth factors signal some cells at the edge of the ectoderm to become epidermis cells. The remaining cells in the center form the neural plate. If the signaling by growth factors were disrupted, then the entire ectoderm would differentiate into neural tissue. The neural plate undergoes a series of cell movements where it rolls up and forms a tube called the neural tube, as illustrated in Figure 43.28. In further development, the neural tube will give rise to the brain and the spinal cord. Q: The neural plate undergoes a series of cell movements where it rolls up and forms a tube called what? A:
****
A: neural tube

Problem:OPTIONS:
- the atlantic ocean
- eastern aisa
- northern africa
- southern asia

Answer the following question given this paragraph: Monsoons are like land and sea breezes, but on a larger scale. They occur because of seasonal changes in the temperature of land and water. In the winter, they blow from land to water. In the summer, they blow from water to land. In regions that experience monsoons, the seawater offshore is extremely warm. The hot air absorbs a lot of the moisture and carries it over the land. Summer monsoons bring heavy rains on land. Monsoons occur in several places around the globe. The most important monsoon in the world is in southern Asia ( Figure below ). These monsoons are important because they carry water to the many people who live there. Q: Where does the most important monsoon in the world occur? A:
****
A:
southern asia
