Q: The depth of the atmosphere is greatest where? Read this paragraph and choose the correct option from the provided answers: The depth (distance from top to bottom) of the atmosphere is greatest at sea level and decreases at higher altitudes. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude. On top of Mount Everest, which is the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level. Choices: - under water - the ionosphere - the stratosphere - sea level A:
sea level

(Question)
Q: What are the two types of vesicle transport called? Read this paragraph and choose the correct option from the provided answers: Choices: - dielectric and exocytosis - epithelium and exocytosis - eptocytosis and exocytosis - endocytosis and exocytosis A:
(Answer)
endocytosis and exocytosis

Ques: Q: Prokaryotic organisms, like bacteria, reproduce through what process, where they grow and divide in half? Read this paragraph and choose the correct option from the provided answers: Prokaryotic organisms, like bacteria. Bacteria reproduce through binary fission , where they grow and divide in half ( Figure below ). First, their chromosome replicates and the cell enlarges. The cell then divides into two cells as new membranes form to separate the two cells. After cell division, the two new cells each have one identical chromosome. This simple process allows bacteria to reproduce very rapidly. Choices: - symbiotic fission - singular fission - multiple fission - binary fission A:
Ans: binary fission

(Q).
Q: What kind of bonds does boron form rather than metallic lattices? Read this paragraph and choose the correct option from the provided answers: Boron forms multicenter bonds rather than metallic lattices with delocalized valence electrons. Why does it prefer this type of bonding? Does this explain why boron behaves like a semiconductor rather than a metal? Explain your answer. Choices: - magnetic bonds - electron bonds - bilateral - multicenter A:
(A).
multicenter

Ques:Q: Name the bacteria that make food through photosynthesis and release oxygen into the air? Read this paragraph and choose the correct option from the provided answers: Bacteria called cyanobacteria are very important. They are bluish green in color (see Figure below ) because they contain chlorophyll (but not chloroplasts, of course). They make food through photosynthesis and release oxygen into the air. These bacteria were probably responsible for adding oxygen to the air on early Earth. This changed the planet's atmosphere. It also changed the direction of evolution. Ancient cyanobacteria also may have evolved into the chloroplasts of plant cells. Choices: - fusobacteria - phytoplankton - algae - cyanobacteria A:

Ans:cyanobacteria

Ques:Q: What are the two most common vision problems? Read this paragraph and choose the correct option from the provided answers: Many people have problems with their vision , or ability to see. Often, the problem is due to the shape of the eyes and how they focus light. Two of the most common vision problems are nearsightedness and farsightedness, which you can read about below. You may even have one of these vision problems yourself. Usually, the problems can be corrected with contact lenses or lenses in eyeglasses. In many people, they can also be corrected with laser surgery, which reshapes the outer layer of the eye. For a video about vision problems, go to this URL: http://www. youtube. com/watch?v=ekSGbXt4XdI. Choices: - colorblindness and farsightedness - glaucoma and nearsightedness - colorblindness and nearsightedness - nearsightedness and farsightedness A:

Ans:
nearsightedness and farsightedness
