Answer the following question given this paragraph: Now that you have learned that the cell membrane surrounds all cells, you can dive inside of a prototypical human cell to learn about its internal components and their functions. All living cells in multicellular organisms contain an internal cytoplasmic compartment, and a nucleus within the cytoplasm. Cytosol, the jelly-like substance within the cell, provides the fluid medium necessary for biochemical reactions. Eukaryotic cells, including all animal cells, also contain various cellular organelles. An organelle ("little organ") is one of several different types of membrane-enclosed bodies in the cell, each performing a unique function. Just as the various bodily organs work together in harmony to perform all of a human's functions, the many different cellular organelles work together to keep the cell healthy and performing all of its important functions. The organelles and cytosol, taken together, compose the cell's cytoplasm. The nucleus is a cell's central organelle, which contains the cell's DNA (Figure 3.13). Q: All living cells in multicellular organisms contain an internal cytoplasmic compartment, and a nucleus within the cytoplasm. cytosol, the jelly-like substance within the cell, provides the fluid medium necessary for this? Choices: - meiosis - cell division - apoptosis - biochemical reactions A:
biochemical reactions
Answer the following question given this paragraph: Kinetic energy distribution curves for a liquid at two temperatures T 1 and T 2 . The shaded area is the molecules with enough kinetic energy to escape the liquid and become vapor. Q: When a liquid is heated, molecules with enough kinetic energy escape the liquid and become what? Choices: - invisible - atoms - solid - vapor A:
vapor
Q: Answer the following question given this paragraph: A catalyst is a substance that increases the rate of a chemical reaction. The presence of a catalyst is one of several factors that influence the rate of chemical reactions. (Other factors include the temperature, concentration, and surface area of reactants. ) A catalyst isn't a reactant in the chemical reaction it speeds up. As a result, it isn't changed or used up in the reaction, so it can go on to catalyze many more reactions. Q: A catalyst can increase the rate of what, in general? Choices: - mechanicl reaction - carbon reaction - consumption reaction - chemical reaction A:
A: chemical reaction
Question: Answer the following question given this paragraph: A laser is a device that produces a very focused beam of visible light of just one wavelength and color. Pulses of laser light carry communication signals through optical fibers. Q: A device that produces a very focused beam of visible light of just one wavelength and color is called? Choices: - mirror - microwave - prism - laser A:
Answer: laser

Q: Bond energy is an indication of the amount of energy needed for what to occur? Choices: - physical reaction only - photosynthesis - oxidation - chemical reaction A:
**Answer**
chemical reaction
(Q).
Answer the following question given this paragraph: The female reproductive organ in a flower is the pistil . It consists of a stigma, style, and ovary. The stigma is the top of the pistil. It is sticky to help it "catch" pollen. The style connects the stigma to the ovary. The ovary is where eggs form and seeds develop. As seeds develop, the ovary turns into a fruit . The fruit protects the seeds. It also attracts animals that may eat the fruit and help disperse the seeds. Q: Consisting of a stigma, style, and ovary, the pistil of a flower is what type of organ? Choices: - female neural organ - female immune organ - female respiratory organ - female reproductive organ A:
(A).
female reproductive organ
