For each statement below, indicate whether it is true or false.
1. breaking the hydrogen bond between 2 water molecules is called dissociation.
2. when water dissociates, an oxygen atom separates from the rest of the molecule.
3. the hydroxide ion has an overall charge of negative one.
4. a hydrogen ion is the same as a proton.
5. when a hydrogen ion separates from a water molecule, it usually combines with another water molecule to form a hydronium ion.
6. a hydronium ion has the formula h2o+.
7. in pure water, at 25oc, about 10% of the water molecules are dissociated at any given time.
8. in pure water, the concentration of hydrogen ions always equals the concentration of hydroxide ions.
9. in pure water, the concentration of hydrogen ions is 1 x 107 molar.
10. water dissociates into oppositely charged ions.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
