[Answered] If the ribosomes of a cell were destroyed, what effect would this most likely have on the cell?

[Answered] Give examples of four minerals that can be identified by unique properties. Describe each property. 1. **Quartz**: Identified by its hardness of 7 on the Mohs scale and its conchoidal fracture. 2. **Halite**: Identified by its salty taste and cubic cleavage. 3. **Magnetite**: Identified by its magnetic properties and black streak. 4. **Calcite**: Identified by its reaction with dilute hydrochloric acid (effervescence) and rhombohedral cleavage.

[Answered] Plants need bacteria in order to take up and use which element? A. Carbon B. Oxygen C. Nitrogen D. Hydrogen

[Answered] How do many amoeba-like protists eat?

[Answered] How does the atmosphere insulate Earth?

[Answered] Make analogies for the following cell parts: 1. **Nucleus**: The nucleus is like the brain because it controls all the activities of a cell, just as the brain controls all activities of the body. 2. **Plasma (cell) membrane**: The plasma membrane is like a security gate, as it controls what enters and exits the cell, similar to how a security gate regulates access to a building. 3. **Cytosol (cytoplasm)**: The cytosol is like a swimming pool, providing a medium for the organelles to float and move, much like water in a pool. 4. **Ribosome**: Ribosomes are like factories because they produce proteins, akin to how factories manufacture products. 5. **Rough Endoplasmic Reticulum**: The rough endoplasmic reticulum is like a conveyor belt with workers because it helps in the synthesis of proteins with ribosomes attached to it. 6. **Smooth Endoplasmic Reticulum**: The smooth endoplasmic reticulum is like a detox center, as it is involved in detoxifying chemicals and synthesizing lipids. 7. **Golgi Apparatus**: The Golgi apparatus is like a post office because it modifies, sorts, and packages proteins for delivery. 8. **Lysosome**: Lysosomes are like recycling centers, breaking down waste materials and cellular debris. 9. **Mitochondria**: Mitochondria are like power plants because they generate the energy required by the cell. 10. **Cytoskeleton**: The cytoskeleton is like a building's framework, providing structure and shape to the cell. 11. **Chromatin**: Chromatin is like an instruction manual, containing the information needed for the cell's functions. 12. **Nuclear membrane**: The nuclear membrane is like a fortress wall, protecting the nucleus and regulating access to it. 13. **Nucleolus**: The nucleolus is like a training center where ribosome assembly begins. 14. **Vesicles**: Vesicles are like delivery trucks, transporting materials within the cell and to the cell membrane. 15. **Centrioles**: Centrioles are like organizers, helping in cell division by organizing the spindle fibers. 16. **Vacuoles**: Vacuoles are like storage containers, holding materials and waste products in the cell.

[Answered] How do I use "prokaryote" in a sentence?

[Answered] The maintenance of constant internal conditions in an organism is known as what?

[Answered] People once believed that organisms could grow from food and dirt. How might the study of cells affect this view?
