My doctor told me that birth control pills contain small amounts of estrogen and progesterone, and these hormones prevent me fro

m ovulating. I assume that it has something to do with the levels of the gonadotropins that I asked about earlier. Can you explain this to me?

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.

Sort the examples into proper mechanisms of reproductive isolation.
vovangra [49]
The mechanisms of reproductive isolation prevent the reproduction of two individuals from different species. The prezygotic mechanisms disrupt the stages of reproduction before the forming of the zygote or prevent the mating at the start, and the postzygotic mechanisms affect the stages of reproduction after the forming of the zygote.
So, the first and the third example (the urchins and the grasshoppers) show the prezygotic mechanism, as the two individuals are not able to mate or form a zygote.
The second and the fourth example ( zonkey and the death of a zygote) show the working of the postzygotic mechanisms, as the zygote is formed, but it seems to be inviable, and the zonkeys are sterile, preventing the individual to reproduce.

Is the vagus nerve the heart rate centre of the brain?
koban [17]

Answer:

The vagus nerve has two bunches of sensory nerve cell bodies, and it connects the brain stem to the body. It allows the brain to monitor and receive information about several of the body’s different functions.

Explanation:

The vagus nerve is the longest and most complex of the 12 pairs of cranial nerves that emanate from the brain. It transmits information to or from the surface of the brain to tissues and organs elsewhere in the body.

There are multiple nervous system functions provided by the vagus nerve and its related parts. The vagus nerve functions contribute to the autonomic nervous system, which consists of the parasympathetic and sympathetic parts

The vagus nerve has a number of different functions. The four key functions of the vagus nerve are:

-Sensory: From the throat, heart, lungs, and abdomen.

-Special sensory: Provides taste sensation behind the tongue.

-Motor: Provides movement functions for the muscles in the neck responsible for swallowing and speech.

-Parasympathetic: Responsible for the digestive tract, respiration, and heart rate functioning.
