Classification Why the butterfly belongs to the invertebrates: The first animals to evolve were invertebrates. Fossil evidence of invertebrates dates back to the late Precambrian‚ 600 million years ago. Invertebrates evolved from single-celled microorganisms. Since then‚ invertebrates have diversified into countless forms. An estimated 97 percent of all species are alive today are invertebrates. Invertebrates are united more by what they lack (a backbone) than by shared characteristics. Invertebrates

How did he do this? What was the result

An agar plate is a Petri dish that contains a combination of agar and nutrients that help microorganisms grow. The proper method of setting microorganisms on an agar plate is know as “streaking”. In order to streak‚ the microorganisms are placed on a sterile swab or metal wire‚ which is then dragged lightly against the agar solution‚ leaving behind the microorganisms. The amount of organisms is greatest at the beginning of the streak and lowest at the end of the streak (Madigan

Dr. Seuss wrote Horton Hears a Who over fifty years ago‚ before the cell phone was invented and the values of that book apply to snails! Snails breakdown decaying plants for nutrients‚ then microorganisms consume that waste and effect the soil’s health which effects plants which help consume carbon dioxide. Midwest Pleistocene Vertigo can easily be saved‚ by less human contact‚ grazing should be decreased because decaying leaves is their habitat

2.4 Utilization of polysaccharide degradation products 2.4.1 Chitin degradation products Chitin can be degraded by chitinase which have the ability to degrade chitin directly to low molecular weight chitooligomers‚ which serve a broad range of industrial‚ agricultural‚ and medical functions. It also has a wide-ranging applications including the preparation of pharmaceutically important chitooligosaccharides and N-acetyl-D-glucoseamine‚ and as mosquito control. Chitooligosaccharides have an extensive

Microbiology is the study of microorganisms which must be viewed with the aid of a microscope or electron microscope. The importance of microbiology includes: used in biomedical research‚ creation of medicines‚ environmental applications and new research tools. Disease causing organisms include: protists‚ bacteria‚ viruses and other microorganisms. Bacteria are important for fixing N2 in a usable form for plants. Bacteria and some fungi are important in decomposition and recycling

and Canning. There is one thing first to consider‚ make sure that the fish that is going to be preserve is new and still fresh. The method of Chilling and Freezing; if the fish is exposed to a low temperature environment‚ the growth of the microorganisms could be prevented; this could lead to spoilage prevention. The appropriate temperature is 0 degree Celsius which involves the use of ice or a refrigerator. The use of ice for chilling is very much convenient and widely used in the markets
