Is the variable alcohol when using water and alcohol to see how many drops can fit on a penny?

Yes, in this experiment, the variable "alcohol" refers to the liquid being tested to see how many drops can fit on a penny. By changing the type of alcohol used, you can observe how it affects the number of drops that can fit on the penny due to variations in surface tension and viscosity.


How can you make Coomb's control cells in indirect anti-globulin test?

Preparing Coombs control cells is very easy. To about 10 drops of washed O Positive red cells add 5-6 drops of anti-D antisera. Incubate at 37C for 15 minutes. Wash 4 times then prepare a 3 to 5% cell suspension. To verify reaction, add two drops of AHG into test tube and one drop of newly prepared Coombs cells. Centrifuge on High for 15 seconds,,,should get 1 -2 + reaction.


Why do you observe dew drops in winter morning?

The air contains moisture. In early in the morning specially in winter morning the temperature is less i.e, air is cool. At this temperature air cannot hold all the moisture in it.

Why did different drops have different charges in millikans oil drop experiment?

Different drops had different charges in Millikan's oil drop experiment because they gained or lost electrons as they moved through the chamber, leading to variations in their net charge. This variability in charge allowed Millikan to observe different electrostatic forces acting on the drops and calculate the charge of a single electron.


Why do leopard geckos perform tail drops and what are the reasons behind their ability to regenerate their tails?

Leopard geckos perform tail drops as a defense mechanism to escape from predators. Their ability to regenerate their tails is due to specialized cells in their tail called stem cells, which can grow back a new tail when needed. This helps them survive in the wild by distracting predators and allowing them to escape.
