Kavyanjali Amrit 2 years, 5 months ago

It is given that The radius of circular orbit r = 42250 km The time period of satellite T = 24 hours Distance traveled by satellite to complete 1 revolution = Circumference of a circle S = 2πr Read Full Article Substituting the values S = 2 x 3.14 x 42250 = 265464.58 km When the distance D and time T are given, speed v can be calculated using v =D/T Substituting the values v = 265464.58/(24 × 60 × 60) v = 3.07km/s Therefore, the speed is 3.07km/s

Harshpreet Kaur 2 years, 5 months ago

- A "neuron" is like a tiny messenger cell in your body that sends and receives messages. - A "nerve" is like a big cable made up of lots of these messenger cells bundled together. It helps carry messages between different parts of your body and your brain. So, neurons are the little messengers, and nerves are the big pathways they use to communicate within your body.

The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. The Golgi apparatus packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.

Srishti . 2 years, 6 months ago

Also known as: Golgi body, Golgi complex The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus. While many types of cells contain only one or several Golgi apparatus, plant cells can contain hundreds. 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. Important among these is the modification of carbohydrate groups. Also within the Golgi or secretory vesicles are proteases that cut many secretory proteins at specific amino acid positions
