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

The activation energy must be lowered by 32490 kJ/mol.
<h3>What is activation energy?</h3>
The term activation energy refers to the energy that reactant particles must posses in order for their collision to result in chemical reaction.
Given that for the reactions;
k2/k1 = ![3*10^5](https://tex.z-dn.net/?f=3%2A10%5E5)
So;
= k2/k1 = E1/RT = E2/RT
Taking natural logarithm of both sides;
E2 - E1 = ln(
) × 8.314 × 310.15 = 32490 kJ/mol

Answer:
The 50/50 cotton/polyester blend has been created with both types of fibers to take advantage of the best qualities of each. A 50/50 blend is both breathable and tear-resistant. It is less expensive than 100% cotton and offers comparable comfort.
