Homeostasis by definition is the technical term for the process of maintaining a constant internal environment despite changes in the external environment. The internal environment comprises of blood‚ tissue fluid‚ body cell contents and all metabolic processes taking place inside the body. This process is essential to the survival of a person and to our species as a whole. The liver‚ the kidneys‚ and the brain (hypothalamus‚ the autonomic nervous system and the endocrine system) help maintain

tint of color to it. 3. Research: In my research I was informed about facts and appearances of lipids. First of all lipids are non-polar compounds‚ thus they won’t dissolve in water. This is also known as being hydrophobic. They are made with one glycerol and 3 fatty acids attached‚ known as a triglyceride. Lipids also mostly consist of waxes‚ oils and sterols. The distinct differences between these lipids are simply stated by this question “liquid or solid?”The function of a lipid is to store energy

95% of the dietary fat consumed can be found in the form of triacylglycerol and primarily stored as this form within the adipose tissue (Webb‚ 2012). The structure of triacylglycerol comprise of three fatty acid molecules linked to a three carbon glycerol molecule (refer to figure 2). The biological and physical properties of a triacylglycerol can differ upon the types of fatty acids it comprises of (Mann & Truswell‚

This root tip was putted on a slide and a drop of 80% glycerol was added‚ than a coverslip applied. After coverslip was applied‚ slide was covered with a sheet of blotting paper and squashed gently. Lastly this sample was observed under light microscope both with low power and high power objective. Method 2:

Latent Fingerprint: Methods of Collection In 1892‚ Francisca Rojas was found with intense neck injuries while her two sons were found with their throats cut open and dead. Francisca Rojas fanatically accused her neighbor who‚ under extreme interrogation‚ would not confess of committing murder and injuring Rojas’s neck. Inspector Alvarez‚ the head of the case‚ went to the crime scene and found a bloody fingerprint next to where the boys laid. After comparing the fingerprint to those of the neighbor

The liver is the largest organ in the entire‚ normal human body. It weighs anywhere from 2.5 to 3.3 pounds. With its large size it is also a very resilient organ. Up to 3/4 of its cells can be removed before is ceases to function. It is red-brown organ roughly shaped like a cone. The liver is located in the upper right abdominal cavity immediately beneath the diaphragm. Without the liver‚ we could not survive. It serves as the body’s chemical factory and it regulates the levels of most of the main
