Answer the following question given this paragraph: Magma collects in magma chambers beneath Earth's surface. Magma chambers are located where the heat and pressure are great enough to melt rock. These locations are at divergent or convergent plate boundaries or at hotpots. Q: What area beneath the earth's surface do magma collects? Choices: - hot chambers - underneath chambers - erosion chambers - magma chambers A:
magma chambers

Answer the following question given this paragraph: Facilitated Diffusion Across a Cell Membrane. Channel proteins and carrier proteins help substances diffuse across a cell membrane. In this diagram, the channel and carrier proteins are helping substances move into the cell (from the extracellular space to the intracellular space). Q: Channel proteins and carrier proteins help substances diffuse across what? Choices: - endoplasmic reticulum - ribosomes - cytoplasm - cell membrane A:
(Answer)
cell membrane
Ques: Answer the following question given this paragraph: View the University of Michigan WebScope at http://virtualslides. umich. edu/Histology/EMsmallCharts/ 3%20Image%20Scope%20finals/054%20-%20Peripheral%20nerve_001. svs/view. apml?listview=1& (http://openstaxcollege. org/l/nervefiber) to see an electron micrograph of a cross-section of a myelinated nerve fiber. The axon contains microtubules and neurofilaments that are bounded by a plasma membrane known as the axolemma. Outside the plasma membrane of the axon is the myelin sheath, which is composed of the tightly wrapped plasma membrane of a Schwann cell. What aspects of the cells in this image react with the stain to make them a deep, dark, black color, such as the multiple layers that are the myelin sheath?. Q: The axon contains microtubules and neurofilaments that are bounded by a plasma membrane known as what? Choices: - exolemal - axolenon - xerophyte - axolemma A:
Ans: axolemma
(Q).
Answer the following question given this paragraph: A theory is constantly tested. If some data does not agree with the theory, the theory can be revised. If the theory cannot match the data, it is thrown out. That being said, sometimes a theory is well-established; it has a lot of evidence to back it up. A well-established theory is unlikely to be overthrown. It may just need to be modified a bit. But science does not prove anything beyond a shadow of a doubt. Q: In science, what is constantly tested, sometimes revised, sometimes thrown out and sometimes well-established? Choices: - a technique - a study - a variable - a theory A:
(A).
a theory
Ques:Answer the following question given this paragraph: Q: Phagocytosis, pinocytosis, and receptor-mediated endocytosis are the three types of what? Choices: - modulators - mitosis - nanoparticles - endocytosis A:

Ans:endocytosis
