For the most part‚ life is cellular. Although there are several other requirements‚ that an organism needs to be considered alive. These requirements are macromolecules‚ it needs to have metabolism‚ and be able to reproduce. If something has all of these things then it can be considered alive. The first requirement is that it has to have cells. Beings also need macromolecules because they need energy. The four macromolecules are carbohydrates‚ lipids‚ proteins‚ and nucleic acid.

The term vaccination may make you panic but it really isn’t. The vaccination is the process by which the doctor will inject you a bit of disease germ that is very weak or dead. Vaccine will not contain any substance which makes you sick. The vaccination is the process of boasting your body’s immune system. You can be vaccinated for each

Lab 11: Mitosis Mitosis is a part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes‚ each in its own nucleus. Mitosis has several phases during the cell cycle. The experiment obligated pictures of onion root tips under the microscope. The pictures had cells and chromosomes. The pictures also had different phases of mitosis in them. As my hypothesis‚ cells stay in the interphase the longest. To begin the experiment‚ there were pictures

Minimal Organism “A minimal genome is generally defined as the smallest set of genes that allows for replication of the organism in a particular environment (Cho‚ M.‚ 1999). The creation of these minimal genomes can be helpful and harmful at the same time. There are many opinions out there about the subject‚ I will share some of those and my position on the subject. First let me just start with my personal position on minimal genomes. I personally feel that the use of them is very important and the

Evolution has many different ways of making organisms all better‚ faster‚ and more adept to live. Four big categories of the mechanisms of evolution are natural selection‚ gene flow‚ genetic drift‚ and mutations. The majority of the time‚ nature goes by a trial and error system that can take up many centuries to come up with a change that is beneficial. Natural selection is the process in which nature removes its mistakes in the trial and error process. For example‚ an albino bird in a forest environment

One major ways for the survival of all organisms is called adaptation. When it comes to Intertidal Organisms their no different. Intertidal Organisms inhabit the specific area between low tide and high tide next to the rocks on the coasts‚ marshes and or wetlands. Theses organisms can be from sea stars to types of algae and many more. As the tides come in‚ the habitat of intertidal organisms are sprayed with salt water. Then after the tide depletes‚ the habitat is exposed to the sun. It makes
