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

Using it's concept, it is found that the sample mean of cars sold per week is of 4.96.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, the sum of the 26 observations is given by:
S = 1 + 1 + 4 + 2 + 4 + 10 + 8 + 5 + 9 + 6 + 1 + 5 + 6 + 5 + 7 + 1 + 4 + 6 + 8 + 9 + 2 + 5 + 9 + 5 + 3 + 3 = 129.
Hence the mean is given by:
M = 129/26 = 4.96.

In geometry, the median of the triangle is a line segment that connects between the vertex in the triangle and the midpoint of the side opposite to this vertex.
So, the median is mainly the bisector of a side.
Based on this, since PM is the median of the side NO, then M is the midpoint of NO and the measure of the side MN is half that of NO
