Saturated because its all with a single bond (C-C)

For example..

Lampakk je there's a single bond with more than one stroke, it's immediately unsaturated!

How to differentiate Alkane (Saturated Hydrocarbon) with Alkene (unsaturated hydrocarbon)??? Alkane - A has one line through, therefore (C - C) AlkEne - E has more than one like, therefore (C=C) or triple covalent bond (C (triple line) C)

T - Thyroid Gland

1. Thyroxine hormone - controls rate of metabolism - controls physical and mental development in children

A - Adrenal Gland

1. Adrenaline - prepares your body to act during an emergency

P - Pancreas

1. Insulin - Controls glucose level in the blood by converting excess glucose into glycogen to store in the livers

O - Ovary

1. Oegesterone - controls female secondary sexual characteristics - stimulates production of ova 2. Progesterone - maintains thickness of uterus wall for implantation of embryo

T - Testis

1. Testerone - controls male secondary sexual characteristics - stimulates sperm production
