Answer the following question given this paragraph: Ribosomes are the organelles on which proteins are made during protein synthesis . Ribosomes are found throughout the cytosol of the cell and attached to the endoplasmic reticulum organelle. Ribosomes order amino acids using messenger RNA (mRNA) as a template in a process called translation. Ribosomes are made from complexes of ribosomal RNAs (rRNA) and proteins called ribonucleoproteins . Each ribosome is divided into two subunits. The smaller subunit binds to the mRNA pattern, while the larger subunit binds to the transfer RNA (tRNA) and the growing polypeptide chain. More about the ribosome will be discussed in the Cell Structures: Ribosomes (Advanced) concept. Q: What are the organelles on which proteins are made during protein synthesis called? Choices: - mitochondria - lysosomes - fibroblasts - ribosomes A:
ribosomes

Answer the following question given this paragraph: In the 1780s, an American scientist named Benjamin Thompson, also known as Count Rumford, was hired by the Elector of Bavaria to supervise the manufacture of cannons. During the manufacturing process, teams of horses harnessed to a large-toothed wheel supplied the power needed to drill a hole several inches in diameter straight down the center of a solid brass or bronze cylinder, which was cooled by water. Based on his observations, Rumford became convinced that heat and work are equivalent ways of transferring energy. Q: According to count rumford, which two are equivalent ways of transferring energy? Choices: - addition and multiplication - osmosis and heredity - time and space - heat and work A:
(Answer)
heat and work
Ques: Answer the following question given this paragraph: We see many objects out in space that emit light. We see other objects that emit other types of electromagnetic radiation. The matter we can see is contained in stars. The stars are contained in galaxies. Scientists think that stars and galaxies make up only a small part of the matter in the Universe. The rest of the matter is called dark matter . Q: What is the area of our universe that isn't stars and galaxies called? Choices: - nebula - solar systems - galaxies - dark matter A:
Ans: dark matter

Answer the following question given this paragraph: Convection within the Earth's mantle causes the plates to move. Mantle material is heated above the core. The hot mantle rises up towards the surface ( Figure below ). As the mantle rises it cools. At the surface the material moves horizontally away from a mid-ocean ridge crest. The material continues to cool. It sinks back down into the mantle at a deep sea trench. The material sinks back down to the core. It moves horizontally again, completing a convection cell. Q: What does convection within the earth's mantel cause? Choices: - volcanos - hurricanes - microorganisms to move - plates to move A:
(A).
plates to move
Ques:Answer the following question given this paragraph: After puberty, an egg develops in an ovary about once a month. As you can see in Figure below , the egg rests in a nest of cells called a follicle. The follicle and egg grow larger and go through other changes. Q: What is the nest of cell an egg rests in called? Choices: - mitochondria - pod - epidermis - follicle A:

Ans:follicle
Ques:Answer the following question given this paragraph: Cell phone signals are carried through the air as microwaves. You can see how this works in the Figure below . A cell phone encodes the sounds of the caller's voice in microwaves by changing the frequency of the waves. This is called frequency modulation. The encoded microwaves are then sent from the phone through the air to a cell tower. From the cell tower, the waves travel to a switching center. From there they go to another cell tower and from the tower to the receiver of the person being called. The receiver changes the encoded microwaves back to sounds. Q: What is the name of the mechanism in which sounds are encoded in microwaves by changing their frequency? Choices: - molecular modulation - shape modulation - mechanical modulation - frequency modulation A:

Ans:
frequency modulation
