Answer:
In a cell with 10 chromosomes undergoes mitosis, the result are 2 daughter cells each with 10 chromosomes
Explanation:
Cells have the ability to reproduce or replicate through 2 processes:
Mitosis
Meiosis
Mitosis differs from meiosis because the final result is always
2 daughter cells
The daughter cells are identical to the mother cell and this includes the same number of chromosomes
This means in mitosis 1 cell with 10 chromosomes leads to two identical cells each with 10 chromosomes.
Populations at genetic equilibrium often occur in nature
Answer:
The endometrial lining is shed during menstruation and is then regenerated by the hormone estrogen.
Explanation:
The menstrual cycle can be described in terms of:
1. <u>OVARIAN cycle</u>: divided into
-Follicular phase of variable length lasting between 7 and 21 days.
-Ovulation
-Luteal phase which is fairly constant and lasts between 12 and 16 days.
The most common cycle length is 28 days and this occurs in 15% of women in their reproductive age
.
The duration of flow is between 2-6 days.
2. <u>ENDOMETRIAL cycle</u>: divided into
-Proliferative phase where there is increase in growth of the functional layer and the endometrial glands under the influence of oestrogen.
-Secretory phase where endometrial changes are influenced by progesterone activity.
The endometrium is made up of the basal layer and the functional layer.
The basal layer remains intact throughout the cycle while the functional layer is shed during each menstruation.
