Answer:
The ingestion of a meal high in fat content would cause <em>obesity </em>to occur.
The variable that researchers manipulate is the independent variable.
The reason for this is because in experiments different manipulations are often introduced. The sole purpose of these manipulations is to see whether they will affect our independent variable and if they will change its value.
During bread making, metabolism of simple sugars by yeast produces carbon dioxide which makes the bread rise.
The essential ingredients of bread dough are flour, water and yeast. As soon as these ingredients are stirred together, enzymes in the yeast and the flour cause large starch molecules to break down into simple sugars.
The yeast metabolizes these simple sugars and exudes a liquid that releases carbon dioxide and ethyl alcohol into existing air bubbles in the dough. If the dough has a strong and elastic gluten network, the carbon dioxide is held within the bubble and begins to inflate it, just like someone blowing up bubble gum.
As more and more tiny air cells fill with carbon dioxide, the dough rises, and so we see bread rising.
Answer:
Digestive system and Circulatory system
Explanation:
The Digestive system has the stomach, small and large intestine- these are all responsible for breaking down food into smaller pieces and on the other hand the circulatory system helps to distribute the broken food around the body for necessary absorption by the body cell.
It is useful to doctors because functional brain imaging helps doctors prepare for brain surgery in patients who have a diagnosis of a brain tumor or a seizure disorder.
