Ques: Answer the following question given this paragraph: Glial Cells Glial cells, or neuroglia or simply glia, are the other type of cell found in nervous tissue. They are considered to be supporting cells, and many functions are directed at helping neurons complete their function for communication. The name glia comes from the Greek word that means "glue," and was coined by the German pathologist Rudolph Virchow, who wrote in 1856: "This connective substance, which is in the brain, the spinal cord, and the special sense nerves, is a kind of glue (neuroglia) in which the nervous elements are planted. " Today, research into nervous tissue has shown that there are many deeper roles that these cells play. And research may find much more about them in the future. There are six types of glial cells. Four of them are found in the CNS and two are found in the PNS. Table 12.2 outlines some common characteristics and functions. Q: What nervous tissue cells play a supporting role to neurons? Choices: - reissner cells - mammalian cells - axial cells - glial cells A:
Ans: glial cells
(Q).
Answer the following question given this paragraph: The electron cloud of a helium atom contains two electrons, which can normally be expected to be equally distributed spatially around the nucleus. However, at any given moment the electron distribution may be uneven, resulting in an instantaneous dipole. This weak and temporary dipole subsequently influences neighboring helium atoms through electrostatic attraction and repulsion. It induces a dipole on nearby helium atoms (see Figure below ). Q: A weak and temporary dipole that influences nearby atoms through electrostatic attraction and repulsion is known as what? Choices: - a fused dipole - an incomplete dipole - an debased dipole - an instantaneous dipole A:
(A).
an instantaneous dipole
Ques:Answer the following question given this paragraph: In order to live on land and in water, frogs have three eyelid membranes: one is see-through to protect the eyes underwater, and the two other ones let them see on land. Frogs also have a tympanum , which acts like a simple ear. They are found on each side of the head. In some species, the tympanum is covered by skin. Q: How many eyelid membranes do frogs have? Choices: - two - four - one - three A:

Ans:three
