     Choose the accurate answer  To view live  cells in a dash we need a/in  inverted microscope  up-right microscope  electron microscope  good microscope  Blood serum must be added to mammals an cell media because, it has nutrient components  it has growth factors & signaling molecules that include cell growth.  Mammalian cells need blood  Blood serum is required for oxygen &CO;_2 transport  mammalian cells grows until they cover the entire surface of the first of the duty/flask where they touch on another point they stop growing this phenomenon is correctly known as  Overgrowth inheritance  touching inhibition  contact inhibition  growth factor-induced inhibition.  Choose the best accurate a when cells crowded on the dish with no or very little spaces between them, we are them as being  crowded  saturated  overgrown  confluent  when cells stop growing as described in questions 19 & 20 above, to prevent excessive cell death they must be _____  discarded in biohazard container  Fed with more rich media to enhance robust growth  Provided with growth factors  Passaged  choose the most accurate answer: To split mammalian first we aspirate the media, cells, then we  wash with 1X PBS and apply trypsin  wash with 1X PBS and apply media  Wash with buffer and apply trypsin  wash with 1X PBS and apply pepsin  
  
  Solution
1. Upright microscope
2. Blood serum has growth factors and signalling molecules which induce cell growth.
3. Contact inhibition
4. Discard in a biohazard manner.
5. Wash with 1x PBS and then add trypsin.
These are tge methods of animql cell culture and their subculturing is done by passaging.
