I know how meiosis seperates into four sex cells with half the amount of chromosomes so that the offspring (after combined with sex cell of the opposite gender), will have 46 chromosomes. What I don't get is...

>> In females... after it splits...one egg with 23 chromosomes results. Then how can more meiosis form, since theres only one egg with only 23 chromosomes now??

Hypothesis:If the enzyme is boiled,it will become denatured and no longer function.

Materials:We use strips of paper and we use many different kinds of liquid like gatorade,milk,lactase,milk+lactase,milk+boiled water

Procedure:We used strip of paper and we each dipped it in four different kinds of liquid and after that we check if the paper turned into a different color or is the same color.

Discussion:?

Hypothsis:?
Can you guys please help me with the discussion and hypothesis?PLEASE

Hypothesis:If the penny has too much water on top of it,it will spill.

Materials:We use tap water,penny,2 cups,dropper,paper towels,soap(dish),Ajax

Procedure:The first thing we did is we got tap water and try putting several drops on the penny without spilling it and then we got soap and did the same thing.We checked to see whether the tap water or soap water can stay the longest without spilling.
