Answer the following question given this paragraph: Punta Arenas, Chile is the world's most southern city. At such a high latitude, winters are exceedingly cold and dark. Unlike the children pictured above, the children in Punta Arenas must stay inside to avoid the cold. Of course, they look forward to spring when they can go out to play. But some years, it is too dangerous for the children to go outside. The ozone hole has moved north. Too much of the Sun's harmful UV radiation gets through. Q: In some parts of the world, too much of the sun's harmful uv radiation gets through because of a hole in what layer? A:
OPTIONS:
- mesosphere
- troposphere
- thermosphere
- ozone
ozone

Answer the following question given this paragraph: In other materials, electrons fill the orbitals of the atoms that make up the material in a way to allow for each atom to have a tiny magnetic field, giving each atom a tiny north and south pole. There are large areas where the north and south poles of atoms are all lined up in the same direction. These areas are called magnetic domains . Generally, the magnetic domains point in different directions, so the material is still not magnetic. However, the material can be magnetized by placing it in a magnetic field. When this happens, all the magnetic domains become aligned, and the material becomes a magnet. This is illustrated in Figure below . Materials that can be magnetized are called ferromagnetic materials . They include iron, cobalt, and nickel. Q: Materials that can be magnetized are called? A:
OPTIONS:
- atoms materials
- iron materials
- inclusions materials
- ferromagnetic materials

Answer: ferromagnetic materials

Question: Answer the following question given this paragraph: Platelets and Coagulation Factors Blood must clot to heal wounds and prevent excess blood loss. Small cell fragments called platelets (thrombocytes) are attracted to the wound site where they adhere by extending many projections and releasing their contents. These contents activate other platelets and also interact with other coagulation factors, which convert fibrinogen, a water-soluble protein present in blood serum into fibrin (a non-water soluble protein), causing the blood to clot. Many of the clotting factors require vitamin K to work, and vitamin K deficiency can lead to problems with blood clotting. Many platelets converge and stick together at the wound site forming a platelet plug (also called a fibrin clot), as illustrated in Figure 40.8b. The plug or clot lasts for a number of days and stops the loss of blood. Platelets are formed from the disintegration of larger cells called megakaryocytes, like that shown in Figure 40.8a. For each megakaryocyte, 20003000 platelets are formed with 150,000 to 400,000 platelets present in each cubic millimeter of blood. Each platelet is disc shaped and 24 m in diameter. They contain many small vesicles but do not contain a nucleus. Q: Thrombocytes are more commonly known by what name? A:
OPTIONS:
- chromosomes
- molecules
- droplets
- platelets
Answer: platelets

input with options: Answer the following question given this paragraph: 3. The third step is the division of the rest of the cell. This is called cytokinesis, as it is in a prokaryotic cell. During this step, the cytoplasm divides, and two daughter cells form. Q: The cytoplasm divides during what stage of the cell cycle? A:
OPTIONS:
- electrolysis
- birthing
- capitis
- cytokinesis
output: cytokinesis

Q: Answer the following question given this paragraph: Animal behavior is any way that animals act, either alone or with other animals. Q: What do we call any way that animals act, either alone or with other animals. A:

OPTIONS:
- typical behavior
- animal habits
- animal communication
- animal behavior

A: animal behavior

OPTIONS:
- hydro plant
- turbine
- combustion aquifer
