The steps of fertilization and the preparations for cleavage are;
1. Oocyte at ovulation
2. Fertilization & oocyte activation
3. Pronuclei develop & DNA synthesis occurs
4. Spindle formation begins
5. Amphimixis occurs & cleavage begins
6. First cleavage forms two blastomeres
<h3>What are the steps in Fertilization?</h3>
Fertilization is the process of formation of zygote by the fusion of female gamete (egg) and male gamete (sperm). Each month an egg is released by an ovary. During copulation, the sperm enters and fuses with an egg.
Now the steps of fertilization and the preparations for cleavage are arranged as follows in sequence;
- 1. Oocyte at ovulation
- 2. Fertilization & oocyte activation
- 3. Pronuclei develop & DNA synthesis occurs
- 4. Spindle formation begins
- 5. Amphimixis occurs & cleavage begins
- 6. First cleavage forms two blastomeres

From the balanced equation we have:
3Mg + N2 ............> Mg3N2
we can see that:
3 moles of magnesium react with 2 moles of nitrogen.
This means that:
72 grams of magnesium are required to react with 28 grams of nitrogen.
Therefore, to calculate the amount of Mg needed to react with 10 grams of N2, all you have to do is cross multiplication as follows:
mass of Mg = (10*72) / 28 = 25.714 grams
