3. Deline photosynthesis.6. Clouds and rain are moving yet they are non-living. Why?7Alba |
| Answer» <p>Life is not necessary to make things move. All that is required is a source of energy than can be converted into kinetic energy in the said objects, and they will move. For clouds, the energy source is the Sun, which heats the air, which then moves and the clouds go with it. For rain, it is formed from water vapor in clouds and falls under gravity.</p><p>Long before life appeared in the universe, stars formed and died and things moved a lot. Until stars had gone through a complete life cycle and created the elements heavier than hydrogen, life was not possible. To get the heaviest elements, you need stars that become supernovae. The go bang in a fairly spectacular way and stuff moves out of them very quickly. Only after they do that does life have the raw material to begin, because you don’t get planets until after the heavier elements form.</p> <p>Life is not necessary to make all things move. the pressure and force of air make them move</p> | |

5. Describe Endoplasmic reticulum. |
| Answer» <p>Theendoplasmic reticulum(ER) is a type of organelle found in eukaryotic cells that forms an interconnected network of flattened, membrane-enclosed sacs or tube-like structures known as cisternae. </p><p> The roughendoplasmic reticulum is especially prominent in cells such as hepatocytes.</p> | |
| 2848. |
what is the function of endoplasmic reticulum? |
| Answer» <p>The endoplasmic reticulum (ER) is an organelle found in the cells of eukaryotic organisms. It is an interconnected network of flattened sacs or tubes encased in membranes. These membranes are continuous, joining with the outer membrane of the nuclear membrane. ER occurs in almost every type of eukaryotic cell except red blood cells and sperm cells.</p><p>Endoplasmic reticulum has two types, rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). Rough ER is studded with ribosomes, the site of protein synthesis. This type of ER is especially prominent in certain kinds of cells like hepatocytes where active protein synthesis occurs. Smooth ER doesn't have ribosomes and is very important to the process of metabolism.</p><p>Endoplasmic reticulum has a number of jobs within the cell. This includes the folding and transport of various proteins, specifically carrying them to the Golgi apparatus. Someother proteins, mostly the glycoproteins, move across the ER's membrane.</p><p>The ER is also responsible for marking these proteins that it transports with a signal sequence. Other proteins are headed outside the ER, so they are packed into transport vesicles and moved out of the cell via the cytoskeleton.</p><p>Basically, the ER is the transportation system of the eukaryotic cell, and its proteins are contained within it until they are needed to move.</p> | |
