Causes of Variation. Variation is a result that leads to a difference or deviation (for example‚ structure‚ form‚ function) from the recognised norm or standard. It is a modification in structure‚ form or function in an organism‚ deviating from other organisms of the same species or group. There are two types of variation: interspecific variation and intraspecific variation. Interspecific variation is when one species differs from another like mammals differ from fish. These differences are explained

anthropology that can be described as the study of humans. These types of anthropologists focus mainly on identifying and constructing a biological profile based off of old/ancient remains. They do this by estimating age‚ sex‚ body type‚ and ancestry as well as identifying certain characteristics like diseases and injuries that could help in identifying the cause of death. To determine these things they start off by asking themselves a number of questions such as whether or not the fossil is bone

math and I despise it. These are all examples of variation. Variation is a subject that affects our daily lives and decisions we make every single day. Each individual on planet Earth is different and to me that is what the definition of variation is. Because we are all different‚ grow up different‚ and all achieve different goals we are all going to make unique choices throughout our lifetimes. In the medical field we all want to keep variations to a minimum. I believe that implementing evidence

The Biological Importance of Water. Water is a material that is essential for all life on earth. The fact that water makes up between 60 and 95 percent of all living organisms clearly shows the biological importance of this compound. The way that water is structured and its properties lead to it being one of the most individual and vital compounds on earth. Water molecules are dipolar‚ meaning they have a positively charged and a negatively charged region. A water molecule consists of two hydrogen

The Biological Importance of Water for Living Organisms Water is made up of two elements‚ 2 positively charged hydrogen molecules and one negatively charged oxygen molecule. Water molecules have uneven charge distribution as one end of the molecule is slightly positive and the other slightly negative‚ this is called polar. Ionic substances such as sodium chloride dissolve easily in water because the positively and negatively charged ions are separated due to the dipole nature of water. As water

The Biological Importance of Water Water is perhaps the most important molecule for the survival and life of organisms. On the surface of the planet there is obviously much more area of water than land‚ which shows its significance. The fact that water makes up 60-95% of all living organisms shows the incredible biological importance of water. Water has many uses and roles‚ one of them it being used as a support unit in plants. The uptake of water by plant cells creates a pressure against the rigid

The Biological Importance of Water! The ultimate importance of water is none other than the fact that life cannot exist without it. Water being the major component of our body cells‚ typically making 70-95% of it‚ constructs the body mass with approximately 80% being water. Humans are not the only ones who contain the valued material but other creatures like the jellyfish hold 96% of water as their body mass. The structure of the water molecules enables it to have extreme properties that are

The Biological Importance of Lipids Lipids are organic compounds found in all types of plant and animal cells. They always contain carbon‚ hydrogen and oxygen‚ however the relative amount of oxygen is less than the amount of carbohydrates in lipids. Lipids are polymers and the long chains of repeating units are joined together in a condensation reaction where water is also produced. The most common types of lipids are triglycerides‚ phospholipids and waxes. Triglycerides are formed by three fatty

The Biological Importance Of Water Water plays a huge role in our lives‚ the molecule which is comprised of two atoms of hydrogen and one atom of oxygen bonded together has many complex properties. The molecule maintains a bent shape due to its tetrahedral arrangement and the negative lone pair of electrons on the oxygen. The electrons from both hydrogen and oxygen are joined covalently but the difference in electronegativity lets the electrons from hydrogen get pulled slightly toward the oxygen

occurs “when repeated panic attacks are followed by at least one month of worrying about having another attack.” There are many theories regarding the causes of panic disorder. Including genetic variations‚ uncontrollable breathing habits‚ and stressful life changes. Typically‚ individuals with panic disorder report their attacks to have no obvious cause. This makes studying panic
