Your friend is trying to learn about how to kill bacteria. She reads the preservatives such as citric acid are added to foods be
cause the acidic environment kills bacteria by denaturing the proteins. She thinks this sounds like a lot of scientific jargon and asks you what it means. How can you explain it in simpler terms? A. Denaturing their proteins means that the proteins in bacteria are converted into carbohydrates.
B. The acid causes the cells to swell and burst open, also known as denaturation.
C. Denaturing means that the proteins of the bacteria lose their structure and can't function, so the bacteria die.
D. Denaturing refers to the fact that bacterial cells divide too quickly and die.
C. Denaturing means that the proteins of the bacteria lose their structure and can't function, so the bacteria die.
Explanation:
Denaturing is a term used to describe the loss or change of the structural shape and form of protein as a result of external influences such as heat, inorganic salts, exposure to bases or acids, and polarity of solvents. When protein become denatured, they lose their structure or shape, and therefore lose their functionality.
Bacteria contain proteins, and when exposed to acidic environment, their protein becomes denatured. As a result of this, various functions ceases in the bacteria leading to death.
A dermatome represents the unilateral area of skin on the body that is innervated by fibers from the sensory portion of a single spinal nerve coming from the spinal cord. Each spinal nerve contains spinal roots (anterior and posterior) that come together to form the spinal nerve.
Plants need water and sun to create their food source, glucose. When the plant was left in the closet it didn't have access to the sun. One of the requirements of life is that all living things need energy/have a metabolism. Without food the plant eventually died.
roots spread out underground like the branches of a tree as to get sufficient water and nutrients form the soil to transport to the other parts of the tree for its own growth , by spreading out roots tend to collect or suck the maximum nutrients
