What are ex-ovo experiments?
Ex-ovo experiments involve studying embryos outside the egg environment, allowing for controlled observations and manipulations.
Why is mechanical force important in embryonic development?
Mechanical forces influence cell shape, movement, and organization, which are critical for proper morphogenesis.
How are the eggs prepared for the experiment?
Eggs are cleaned with 70% ethanol and arranged in a specific orientation for incubation.
What temperature is required for incubation?
The incubator should be set to 37.5 degrees Celsius.
What humidity levels are maintained during the experiment?
Humidity should be kept between 48 to 55% for optimal embryo development.
