Water properties: 
• Cohesion: like molecules attract to each other 
• Water is a polar molecule that forms a hydrogen bond with other water molecules. 
• The negatively charged oxygen atom of one water molecule forms a hydrogen bond with a positively 
• charged hydrogen atom of another water molecule. 
This attractive force between these molecules is called cohesion which helps plants draw water from the root 
through the xylem to the leaf

Biology 410. Research On Tympanic Membrane And The Thyroid Gland 1. Graded A
The body has several organs for clinical decision-making, which the physician must evaluate and document. The two organs are perhaps the most critical in our life. The thyroid gland is essential in hormone secretion, which facilitates development and growth control (Stomackin et al. 2019). Efficient evaluation of the client's medical background, recognizing the medical results for a problem, thyroid test while making a conscious SOAP report enables systematic diagnosis and infection control.
