<span>Prior to drawing blood for a blood donation, the nurse will clean the arm with a betadine solution. this form of antimicrobial control is called ANTISEPSIS.

Antisepsis is the practice of using antiseptics or antimicrobial substances to reduce or eliminate the possibility of infection by applying it to living tissue or skin.   

Betadine solution is an antiseptic solution.</span>

Each of the following relates to an aspect of evolution by natural selection. Explain the following. ii. Natural selection and t
dlinn [17]

         The first one, ii. Natural selection and the formation of inseticide resistant insects or antibiotic resistant bacteria.

          This can be explained in very simple way. As we all know, natural selection works in a way that only that adapted living beings are going to survive through a specific environment, whether it's because they can grab their food without too much work, or even that they can adapt to the weather. When we use inseticide, we are killing lots of non-resistant insects, and what's left are those that are resistant to this inseticide, and they'll reproduce again, and again we'll go through the same process, but remember, this insect is now stronger and more resistant that before.

            The second case, iii. speciation and isolation give three examples how it may occur.

            Well. the allopatric speciation and isolation will happen when theres a geographic barrier between one species. This one then is divided into two diffent habitats, but what can divide than could be a mountain, a tree, a river, a rock, anything. And this could be too called as a geographic isolation, because in this new environment, species are going to develop in a different way.

Why are unsaturated fatty acids particularly abundant in the cellular membranes of antarctic fish?
Nutka1998 [239]
Antarctic fish species requires an adaptation to cold environment. Living at cold temperature environment would demand certain biological responses such as cutaneous respiration, enlarged blood vessels, and producing greater amounts of fat. Most of these fat are composed of higher phospolipid levels which are primarily due to phosphatidylethanolamine. This phospolipid is responsible for destabilizing cell membranes and make it more fluid thereby allowing unrestricted blood flow. The fatty acid composition of the membrane lipid is important for membrane fluidity, this is mainly attributed to unsaturated fatty acids which are responsible for decreasing the order of membrane lipids thereby decreasing viscosity. At extremely low temperatures, organisms with low concentration of unsaturated fatty acids would freeze cell membranes. That's why antarctic fishes have higher levels of unsaturated fatty acids.

Animals eat plants and produce carbon dioxide and water. How do animals affect the amount of carbon in Earth's atmosphere?
mrs_skeptik [129]
They do the same thing that all living and breathing things do! They breathe! When they breathe they are doing the same thing you are doing all day everyday. Inhaling oxygen and exhaling carbon dioxide.
