Whilst foods such as ‘meat’ form relatively well -defined groups of raw materials‚ ‘fish’ constitutes a large range of types (some sources recognise over 20‚000 identified species)‚ caught over

carbohydrates (4.7g)‚ and proteins (3.3g). Although molds can and do grow on the surface of yogurt if the yogurt are exposed to air‚ the high moisture contents favors the faster-growing yeasts and bacteria. The deficiency of vitamin B discourages some bacteria. The normal change to be expected in raw yogurt in room temperatures is an alcoholic fermentation by yeasts‚ followed by the oxidation of the alcohol and yogurt acids by film yeast or molds growing on the surface if it is exposed to air or the

called phyla. Traditionally‚ textbooks from the United States used a system of six kingdoms. A fungus (/ˈfʌŋɡəs/; plural: fungi[3] or funguses[4]) is any member of a large group of eukaryotic organisms that includes microorganisms such as yeasts and molds(British English: moulds)‚ as well as the more familiar mushrooms. These organisms are classified as a kingdom‚ Fungi‚ which is separate from plants‚ animals‚protists‚ and bacteria. One major difference is that fungal cells have cell walls that contain chitin

Protozoans (from Greek πρῶτον proton "first" and ζῷα zoa "animals"; singular protozoon) are microorganisms classified as unicellular eukaryotes.[1] While there is no exact definition of the term "protozoan"‚ most scientists use the word to refer to a unicellular heterotrophic protist‚ such as an amoeba or a cilipoopate. The term algae is used for microorganisms that photosynthesize. However‚ the distinction between protozoa and algae is often vague. For example‚ the alga Dinobryon has chloroplasts
Premium Protist Photosynthesis Eukaryote
eukaryotes organisms whose cells have nuclei that normally show characteristics associated with animals‚ most common mobility and heterotrophy. They are often grouped in the kingdom Protista together with the plant-like algae and fungus-like water molds and slime molds. Most algae are classified in the kingdoms Plantae and Chromista‚ and some the remaining forms may be classified as a kingdom Protozoa. The name is misleading‚ since they are not animals. Protozoa have traditionally been divided on the basis

has been proven that temperature does effect the growth of mold. Freezing temperature completely stops the growth of mold. HYPOTHESIS Bread mold will grow faster in a warm and damp environment. Also‚ light‚ temperature‚ & humidity influence the growth rates of bread mold. VARIABLES For this experiment‚ the independent variable is the environment in which the bread slice is kept. The dependent variable is the growth of bread mold. This is determined by inspecting the bread with a magnifying

Bioinformatics – is the application of computational methods to the storage and analysis of biological data Linkage Map – maps the location of several thousand genetic markers on each chromosome Physical Map – Expresses the distance between genetic markers‚ usually as the number of base pairs along the DNA Metagenomics – DNA from a group of species (a metagenome) is collected from an environmental

Observing Protists through Hay Infusion Preparation Abstract: Protists are known to be the very first eukaryotic organisms on earth. The Kingdom Protista was first classified by Haeckel in the year 1866. Now‚ there are many known species of protists. After learning about protists in class‚ the group decided to observe the different species of protists found in pond water. The group prepared a preparation to be able to culture the protists until it was time to view them. After a few days‚ the
