What hormone is produced in the ovaries?
Estrogen A hormone produced by the female reproductive system is called estrogen. It regulates the release of the ovum from the ovary, down the Fallopian tube, and into the uterus. If the egg is fertilized, no new eggs will drop for nearly a year. If it is not fertilized, a new egg will drop in roughly 28 days.

What are the key points for pure substances and mixtures?
Pure substances are those with nearly all molecules identical, or those with a network structure which consists of nearly all repetitions of the same few atoms. A perfectly pure substance is never achievable, but specifications for pure substances range between 90% and 99.9999%. Anything else is a mixture -- mixtures involve 2 or more substances, and are divided into homogeneous (a sample will contain reliably constant proportions of the substances) or heterogeneous (which are "lumpy" so that a sample might be predominantly one sort of pure substance, and another might be quite different).

Why is water called a universal solvent?
Water is considered 'the' universal solvent because more materials are dissolved by it than by any other solvent but it will not dissolve non-polar substances like oil. Water is very polar; which is why many of its properties are different from nearly all substances, such as water's high melting and boiling points, high surface tension, and why it expands when frozen.
