What are the three functions of the Golgi apparatus? The Golgi apparatus is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations. As the secretory proteins move through the Golgi apparatus, a number of chemical modifications may transpire. What would happen to the life of cell if there […]
Can electrons exist alone?
Can electrons exist alone? Electrons have mass, charge, angular momentum, an intrinsic magnetic moment and helicity, but they have no known substructure. No two electrons can occupy the same space at the same time. They are part of every atom but they can exist separately on their own as well. What happens to the atoms […]
How long was the era of nuclei?
How long was the era of nuclei? 380,000 years What did the first Dying stars create? The nucleosynthesis that occurs during the explosion of a supernova produces elements with a higher atomic number than iron, which cannot be created by nuclear fusion. When the first stars died out this way, brand new elements, including gold, […]
What would happen if temperature and precipitation changed in a climate zone?
What would happen if temperature and precipitation changed in a climate zone? Changes in temperature and precipitation can disrupt a wide range of natural processes, particularly if these changes occur more quickly than plant and animal species can adapt. In response, average temperatures at the Earth’s surface are rising and are expected to continue rising. […]
What is the difference between loudness and frequency?
What is the difference between loudness and frequency? Frequency (the number of vibrations or sound waves per second) is measured in Hertz (Hz). A sound that is 4,000 Hz (like the sound the letter “F” makes) has 4,000 waves per second. Intensity (loudness) is the amount of energy of a vibration, and is measured in […]
Which of the following best describes a difference between artificial and natural selection?
Which of the following best describes a difference between artificial and natural selection? The following statement best describes the difference between artificial and natural selection: Natural selection acts without the input of humans: artificial selection requires human input. only via natural selection, genetic drift, migration, or mutation. Which best describes the role of mutations in […]
Had chlamydia for 2 years can I still get pregnant?
Had chlamydia for 2 years can I still get pregnant? Most women who have had chlamydia won’t have any difficulties conceiving that are related to the infection. There may be a greater chance of chlamydia affecting fertility if you have repeated infections or if it goes untreated and causes a condition called Pelvic Inflammatory Disease […]
Can fossils be found anywhere?
Can fossils be found anywhere? For example, many fossils form when plant and animal remains are buried by mud, sand, or soil. This helps to preserve the remains long enough for them to form fossils. Still, fossils can be found just about anywhere. From the tops of mountains to the depths of the seas, fossils […]
What causes static electricity in a person?
What causes static electricity in a person? Static electricity is created when positive and negative charges aren’t balanced. Protons and neutrons don’t move around much, but electrons love to jump all over the place! When an object (or person) has extra electrons, it has a negative charge. Why is my laundry so static? What causes […]
How much time is a parsec?
How much time is a parsec? It is defined as 360×60×60/2π astronomical units (AU), which is equivalent to about 19.17 trillion miles, or about 3.262 light-years. The Star Wars parsec appears to be equivalent to the real-world measurement: The Essential Atlas says a parsec is 3.26 light-years. How many parsecs are in the universe? The […]
