пожалуйста решите кто нибудь - найти молярность раствора если для приготовления 150 мл раствора взяли 10 г KCl

1)сколько граммов цинката калия (K2ZnO2) образуется, если подействовать на 2 моля гидроксида цинка избыточным количеством гидроксида калия?

2) Элементы S (сера) и Se (селен) входят в одно естественное семейство. Составьте формулы высшего оксида, водородного соединения и кислоты, образованных селеном. Запишите химическое уравнение взаимодействия селена с водородом и натрием.

 Пожалуйста помогите, переведите, нужно по биологии

Meiosis 

Now coil up coil up coil up tight if we`re to do meiosis right. Interphase one is almost done marks the start of prophase one.  Now face your partners and to them bow do-sa-do crossover now. Allemande left with your left hand promenade around the land now grab your partner`s chromatid crossing arms you`ll be glad you did. The nuclear membrane breaks down here attach a fibre to your centromere.

The fibres pull the dance is done hold on tight it`s metaphase one. Couples move to the central plate it`s anaphase one so you separate. Now wave goodbye to reach your goal each partner move to the other pole. Telophase one is mighty sad you`re all alone lost what you had. Together we`ll no longer be these parts of you will be dear to me. Prophase, prophase, prophase two the spindle`s coming after you.

 With a fibre stuck to your centromere you`re pulled into the centre here. On the central plate for metaphase two just like before it`s déjà vu. At interphase one you duplicate so that now you can separate. The fibres  tugging this is it time for your chromatids to split. Anaphase, anaphase , anaphase two this time you wave goodbye to you. At telophase two half the team`s on hand you`re feeling sad you`re a single strand. Now this is just your normal state with some luck you`ll procreate. So rest awhile and unwind too as the nuclear membrane surrounds you. Now meiosis is complete four nuclei from one`s the treat. The cytoplasm will divide four gametes formed with you inside. And if we zoom out you will find many more of the same kind and if you`re wondering what`s the use it`s all so you can reproduce… reproduce
