During this step, the cytoplasm divides, and two daughter cells form. Q: The cytoplasm divides during what stage of the cell cycle? Choices: - electrolysis - birthing - capitis - cytokinesis A:
(Answer)
cytokinesis

(Q).
Answer the following question given this paragraph: A food chain is a simple diagram that shows one way energy flows through an ecosystem. Pictured below is an example of a food chain ( Figure below ). Producers form the base of all food chains. The consumers that eat producers are called primary consumers. The consumers that eat primary consumers are secondary consumers. This chain can continue to multiple levels. Q: What is a diagram that shows a single way that energy flows throughout an ecosystem? Choices: - fuel chain - dependent chain - water cycle - food chain A:
(A).
food chain
Ques:Answer the following question given this paragraph: You can see how Mendeleev organized the elements in Figure below . From left to right across each row, elements are arranged by increasing atomic mass. Mendeleev discovered that if he placed eight elements in each row and then continued on to the next row, the columns of the table would contain elements with similar properties. He called the columns groups . They are sometimes called families, because elements within a group are similar but not identical to one another, like people in a family. Q: In the periodic table, elements are arranged from left to right according to what property? Choices: - metallic mass - real mass - major mass - atomic mass A:

Ans:atomic mass
Ques: Answer the following question given this paragraph: Molecules in the cell membrane allow it to be semipermeable. The membrane is made of a double layer of phospholipids (a "bilayer") and proteins ( Figure below ). Recall that phospholipids, being lipids, do not mix with water. It is this quality that allows them to form the outside barrier of the cell. Q: Phospholipids are unable to mix with what? Choices: - nitrogen - solids - air - water A:
Ans:
water
