Answer the following question given this paragraph: Fluid Mosaic Model In 1972, S. Singer and Garth L. Nicolson proposed a new model of the plasma membrane that, compared to earlier understanding, better explained both microscopic observations and the function of the plasma membrane. This was called the fluid mosaic model. The model has evolved somewhat over time, but still best accounts for the structure and functions of the plasma membrane as we now understand them. The fluid mosaic model describes the structure of the plasma membrane as a mosaic of componentsincluding phospholipids, cholesterol, proteins, and carbohydratesin which the components are able to flow and change position, while maintaining the basic integrity of the membrane. Both phospholipid molecules and embedded proteins are able to diffuse rapidly and laterally in the membrane. The fluidity of the plasma membrane is necessary for the activities of certain enzymes and transport molecules within the membrane. Plasma membranes range from 510 nm thick. As a comparison, human red blood cells, visible via light microscopy, are approximately 8 m thick, or approximately 1,000 times thicker than a plasma membrane. (Figure 3.18). Q: What model describes the structure of the plasma membrane as a mosaic of components? Choices: - solid mosaic model - sensors mosaic model - coolant mosaic model - fluid mosaic model A:
(Answer)
fluid mosaic model
Ques: Answer the following question given this paragraph: Evolution happens because of natural selection . Good traits become more common in a population. Bad traits become less common. The deer mouse, species Peromyscus maniculatus gives an example of evolution by natural selection. In Nebraska, this mouse is typically brown. But in places where glaciers dropped lighter sand over the darker soil, the mice are light. Why? Because predators could more easily spot the dark mice on light sand. The lighter mice were more likely to survive and have offspring. Natural selection favored the light mice. Over time, the population became light colored. Enough changes may take place over time that the two types of mice become different species. Q: Evolution happens because of what? Choices: - natural resources - natural change - natural process - natural selection A:
Ans: natural selection
(Q).
Answer the following question given this paragraph: Remember that proteins are made out of amino acids. How does the information in the gene get converted from the language of nucleotides to the language of amino acids? The process is called translation . The amino acids are placed in a specific order during translation. The order is specified by the codons in the mRNA, which is produced during transcription. As the mRNA sequence is based on the gene sequence in the DNA, the order of amino acids that makes the protein is based on the gene sequence as well. Q: What is the name for the process where data in the genes is transferred to amino acids? Choices: - mutation - transpiration - generation - translation A:
(A).
translation
