Explanation:
Menstruation is the cyclic changes taking place in women every month which involves the sloughing of the uterine walls.
The menstrual cycle involves the coordination of two-cycle: the ovarian cycle and the uterine cycle.
The menstrual cycle is controlled by the gonadotrophin hormones which are the Luteinizing hormone (LH) and the Follicular stimulating hormone (FSH) and ovarian hormones which are: progesterone and estradiol.
The level of these hormones during each phase are:
1. Follicular phase / proliferative phases- Estradiol level increases/ FSH level declines
2. Ovulation- LH hormone level at the peak, estrogen level at the peak
3. Luteal phase/ secretory phase- Progesterone and estrogen level elevates / LH and FSH level declines
Answer:
Atypical pneumonia
Explanation:
This is the type of pneumonia caused by uncommon microorganisms types and it’s usually very rare. This type of pneumonia has milder symptoms and can be caused by bacteria, fungi, Protozoa and virus.
It is also known as Walking pneumonia. It is very difficult to culture and can’t be easily detected.
Non-renewable resource
Explanation:
The cheetahs can be considered a non-renewable resource. Non-renewable implies that a resource cannot be replenished at it current rate of depletion.
How much has the cheetah's population declined:
percentage declination =
x 100
Population in 1990 = 100,000
Population today = 12,000
Percentage declination =
x 100 = 83.3%
We can see that the cheetah has suffered a whooping 83.3% decline in their population.
A renewable resource is one that can be replenished as it is being used such as water, air, e.t.c.
