Vladimir79 [104]

Answer:

Hormone levels generally decrease.

Explanation:

<em>The graph showed that hormone levels after ovulation generally decrease.</em>

The menstrual cycle of women generally have 3 phases which include:

  1. <em>The follicular phase</em>
  2. <em>The ovulatory phase</em>
  3. <em>The luteal phase</em>

The follicular phase is characterized by low levels of oestrogen and progesterone and a slightly high level of follicle stimulating hormone which ensures that follicles within the ovary develop.

The ovulatory phase is characterized by a surge in the luitenizing hormone (which stimulates the release of eggs) and follicle stimulating hormone with a decrease in the level of oestrogen and a gradual increase in the level of progesterone.

The luteal phase is characterized by a general decrease in the levels of luitenizing hormone and follicle stimulating hormone while oestrogen level may remain high.

raketka [301]

Answer:

Explanation:

From the question, the total population = 171 i.e (80+71+21)

Genetic frequency therefore; BB = 71/171 = 0.42

Bb = 80/171 = 0.47

bb = 20/171 = 0.12

Allele frequency therefore;

Allele B = 0.42+(0.50×0.47) = 0.66

Allele b = (0.50×0.47)+0.12 = 0.36

Note all values were rounded up to two significant figures
