Answer the following question given this paragraph: Parasitic fungi often cause illness and may eventually kill their host. They are the major cause of disease in agricultural plants. Fungi also parasitize animals, such as the insect pictured in Figure below . Fungi even parasitize humans. Did you ever have athelete's foot? If so, you were the host of a parasitic fungus. Q: Parasitic fungi often cause illness and may eventually do what to their hosts? Choices: - reproduce with them - mutate them - become them - kill them A:
kill them

Answer the following question given this paragraph: Pure nonpolar covalent bonds exist only between two identical atoms. The H-H bond would be 100% covalent, because there is no difference in electronegativity between the two atoms. Q: Pure nonpolar covalent bonds exist only between what? Choices: - two altered atoms - two producing atoms - three altered atoms - two identical atoms A:
(Answer)
two identical atoms
Ques: Answer the following question given this paragraph: Resistance is opposition to the flow of electric charges that occurs when electric current travels through matter. The SI unit of resistance is the ohm (named for the scientist Georg Ohm, whom you can read about below). Resistance is caused by electrons in a current bumping into electrons and ions in the matter through which the current is flowing. Resistance is similar to the friction that resists the movement of one surface as it slides over another. Resistance reduces the amount of current that can travel through the material because some of the electrical energy is converted to other forms of energy. For example, when electric current flows through the tungsten wire inside an incandescent light bulb, the tungsten resists the flow of electric charge, and some of the electrical energy is converted to light and thermal energy. Q: What term means opposition to the flow of electric charges that occurs when electric current travels through matter? Choices: - polarity - antagonism - diffusion - resistance A:
Ans: resistance
(Q).
Answer the following question given this paragraph: Gap genes control the expression of other genes within specific regions of cells in the developing organism. This allows specific genes to be expressed in certain cells at the appropriate stage of development. Q: What is the term for genes that control the expression of other genes within specific regions of cells in the developing organism? Choices: - expression genes - age genes - data genes - gap genes A:
(A).
gap genes
Ques:Answer the following question given this paragraph: When light rays converge behind a lens, a real image is formed. Real images are useful in that you can place photographic film at the physical location of the real image, expose the film to the light, and make a two-dimensional representation of the world, a photograph. Q: What can be formed by converging light rays behind a lens, onto a piece of film? Choices: - a prism - a kaleidoscope - a mirror - a photograph A:

Ans:a photograph
Question: Answer the following question given this paragraph: Buffers are solutions that maintain a relatively constant pH when an acid or a base is added. They therefore protect, or "buffer," other molecules in solution from the effects of the added acid or base. Buffers contain either a weak acid (HA) and its conjugate base (A) or a weak base (B) and its conjugate acid (BH+), and they are critically important for the proper functioning of biological systems. In fact, every biological fluid is buffered to maintain its physiological pH. Q: What are solutions that maintain a relatively constant ph when an acid or a base is added? Choices: - gases - water - liquids - buffer A:
Answer:
buffer
