My doctor told me that birth control pills contain small amounts of estrogen and progesterone, and these hormones prevent me fro
german
Ok... This is a bit complicated but bear with me. In a female's body Estrogen and Progesterone are two of the major used to maintain the menstruation cycle. Gonadotrophic substances are an entirely different topic with it being the hormones FSH and LH (These hormones are released while an egg is in development in the ovaries). 

Without going into even deeper specifics. Estrogen is used by the body signal to ovulate, as well as thicken the uterine walls... Progesterone is used to maintain the uterine walls "after" the egg is fertilized. What the pill is suppose to do is actually force a premature ovulation, which is why there is estrogen. The Progesterone's job as is maintain the uterine wall's endometrium to a low level and helps keep blood loss from a period at a minimum. 

If you need clarification please feel free to question.

Why does an octopus or squid use its tentacles?
spin [16.1K]
Octopus and squid have little suction cups on their tentacles. It helps with sticking onto food (so it doesn't get away) and also helps with sticking into things. If it wanted to camouflage into some rocks, it can use its tentacles to cling to to the rock.

Tentacles can also grab and carry things. Scientists have made tests where they would put a clam in a jar with the lid screwed on. The octopus would grab onto the jar and use its tentacles to twist the lid off.

Without tentacles, octopuses and squids would be pretty helpless and probably couldn't survive in the deep ocean.

How long does it take harry to go 0.7 miles if he can run 1.2 miles in 6 minutes
IgorLugansk [536]

Answer:

Harry will take 21 seconds

Explanation:

Speed = distance covered / time taken

Harry covers 12 miles in 6 minutes so,

the speed of Harry will be 12/6 = 2 miles per minute.

Therefore, if he covers 0.7 miles then time taken by him will be,

Time taken = distance covered / speed

                   = 0.7 / 2

                   = 0.35 minutes

                   = 0.35 x 60 seconds

                   = 21 seconds

I hope this helps :)
