Answer the following question given this paragraph: In eukaryotic cells, the nucleus divides before the cell itself divides. The process in which the nucleus divides is called mitosis. Before mitosis occurs, a cell's DNA is replicated. This is necessary so that each daughter cell will have a complete copy of the genetic material from the parent cell. How is the replicated DNA sorted and separated so that each daughter cell gets a complete set of the genetic material? To understand how this happens, you need to know more chromosomes. Q: The process in which the nucleus divides is called what? Choices: - meiosis - epistasis - cytokinesis - mitosis A:
mitosis

Answer the following question given this paragraph: Like density, the pressure of the air decreases with altitude. There is less air pressing down from above the higher up you go. Look at the bottle in Figure below . It was drained by a hiker at the top of a mountain. Then the hiker screwed the cap on the bottle and carried it down to sea level. At the lower altitude, air pressure crushed it. Can you explain why?. Q: Density and pressure of air decreases with what? Choices: - temperature - humidity - horizontal distance - altitude A:
(Answer)
altitude

(Q).
Answer the following question given this paragraph: Sound waves can travel through many different kinds of matter. Most of the sounds we hear travel through air, but sounds can also travel through liquids such as water and solids such as glass and metal. If you swim underwater or even submerge your ears in bathwater any sounds you hear have traveled to your ears through water. You can tell that sounds travel through glass and other solids because you can hear loud outdoor sounds such as sirens through closed windows and doors. Q: What kind of waves travel through liquids and solids as well as air? Choices: - light waves - mind waves - radio waves - sound waves A:
(A).
sound waves
Ques:Answer the following question given this paragraph: Q: In drosophila, gradients of morphogens encoded by maternal effect genes determine what? Choices: - cell mass - cells axes - body mass - body axes A:

Ans:body axes
Question: Answer the following question given this paragraph: When nonmetals react with one another, the product is a molecular compound. Often, the nonmetal reactants can combine in different ratios and produce different products. Sulfur can also combine with oxygen to produce sulfur trioxide. Q: Sulfur can combine with oxygen to produce what? Choices: - sulfur bioxide - sulfur dioxide - sulfur oxide - sulfur trioxide A:
Answer:
sulfur trioxide
