Answer:
Ultrasound scan to rule out polyps or endometrial hyperplasia of the uterus
Explanation:
Guard cells use osmotic pressure to open and close stomata, allowing plants to regulate the amount of water and solutes within them. In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis
The answer is splitting of water molecules. This happens during the light stage of photosynthesis where light energy from the sun is absorbed by chlorophyll is used to split water molecules into hydrogen ions and oxygen. This process is called photolysis. The hydrogen ions joins the dark stage or the light independent stage, while oxygen gas is either released to the atmosphere or used for cellular respiration.
