In this video we are going to look at a few different ways in which plant hormones can be used. Plant growth hormones (auxins) can be used as selective weedkillers. The selective weedkillers contain growth hormones, that cause the weeds to grow really quickly. This means the weed is absorbing nutr
A hormone is a chemical messenger that is secreted (or released) into our bloodstream by specific organs known as glands. Hormones regulate (or control) many processes in our body, including blood glucose levels, water content in blood, general growth, and blood pressure – just to name a few. They

Hyperparathyroidism is a condition in which one or more of your parathyroid glands become overactive and release (secrete) too much parathyroid hormone (PTH). This causes the levels of calcium in your blood to rise, a condition known as hypercalcemia. #hyperparathyroidism #PTHhormone #parathyroidg
