Answer the following question given this paragraph: 10.2 The Cell Cycle The cell cycle is an orderly sequence of events. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages. In eukaryotes, the cell cycle consists of a long preparatory period, called interphase. Interphase is divided into G1, S, and G2 phases. The mitotic phase begins with karyokinesis (mitosis), which consists of five stages: prophase, prometaphase, metaphase, anaphase, and telophase. The final stage of the mitotic phase is cytokinesis, during which the cytoplasmic components of the daughter cells are separated either by an actin ring (animal cells) or by cell plate formation (plant cells). Q: In eukaryotes, the cell cycle consists of a long preparatory period, called __________ before undergoing cell division. Choices: - metaphase - mitosis - outerphase - interphase A:
(Answer)
interphase
Ques: Answer the following question given this paragraph: In the study of thermochemical processes, things are viewed from the point of view of the system. A chemical reaction or physical change is endothermic if heat is absorbed by the system from the surroundings. In the course of an endothermic process, the system gains heat from the surroundings and so the temperature of the surroundings decreases. The quantity of heat for a process is represented by the letter . The sign of for an endothermic process is positive because the system is gaining heat. A chemical reaction or physical change is exothermic if heat is released by the system into the surroundings. Because the surroundings is gaining heat from the system, the temperature of the surroundings increases. The sign of for an exothermic process is negative because the system is losing heat. Q: If heat is released by the system into the surroundings, a chemical reaction or physical change is called what? Choices: - static - endothermic - biochemical - exothermic A:
Ans: exothermic
(Q).
Answer the following question given this paragraph: Through the process of transformation, the human gene for insulin is placed into bacteria. The bacteria then use that gene to make a protein. The protein can be separated from the bacteria and then used to treat patients. The mass production of insulin by bacteria made this medicine much more affordable. Q: Through which process is the human gene for insulin placed into bacteria? Choices: - migration - mutation - absorption - transformation A:
(A).
transformation
Ques:Answer the following question given this paragraph: Q: Synaptic connections can change over time depending on what? Choices: - weight - diet - age - activity level A:

Ans:activity level

However, only signs that glow with the red-orange color seen in the figure are actually filled with neon. Signs of other colors contain different gases or mixtures of gases. Q: What colors in a neon sign represent real neon? Choices: - purple, blue - blue, green - yellow, white - red, orange A:

Ans:
red, orange
