Hey!
I know it's not just biology but I don't have much time but do have a few questions. So please just give me the correct answers

Question 1:
Which element could form inorganic complex salt?
Zn

2.) The amount of DNA in the nucleus is lowest during

3.) Partial cleavage is related to

macrolecithal eggs
micro- or mactrolecithal eggs
eggs with small amount of yolk

4.) A solution that produces a precipitate upon the addition of a single solute crystal is said to be

unsaturated
colloidal
diluted

Thanks for any help! Best regards

I see, you don't have time, so you will wait for answers? Well, better than if you were in hurry However, I don't think you will get answer here w/o showing your attempt first.
