Compounds can be separated by physical methods is the statement about compounds that is false.
A compound is a molecule that is formed from the combination of two or more different chemical elements. The atoms of the different elements that form a compound are held together by chemical bonds (covalent and ionic) that are not easy to break. The component of a compound can only be separated by chemical means and not by physical methods. An example of a compound is water (H2O) which is composed of hydrogen (H) and oxygen (O) atoms.
<h2>Ovulation </h2>
Explanation:
In women, luteinizing hormone carries out different roles in the two halves of the menstrual cycle
- In week one to two of the cycle, luteinizing hormone is required to stimulate the ovarian follicles in the ovary to produce the female sex hormone, oestradiol
- Around day 14 of the cycle, a surge in luteinizing hormone levels causes the ovarian follicle to tear and release a mature oocyte (egg) from the ovary, a process called ovulation
- For the remainder of the cycle (weeks three to four), the remnants of the ovarian follicle forms a corpus luteum
- Luteinizing hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilization occurs
