1. water molecules have +0 charged ends and can form weak hydrogen bonds . water is said to be a dipolar molecule. 2. The basic uits of CO2 are monosaccharides ‚ characterized by the number of carbon atoms‚ e.g pentose sugars have 5 carbons 3. Two monossaccharids can link together to form a disaccharide . the bond between them is a glycosidic linkage formed in a condensation reaction 4. Starch is a polysaccharide composed of amylose and amylopectin. Its main function is as a storage

Cell Processes and Body Organisation Nucleus The nucleus is the largest‚ most prominent organelle‚ usually spherical and roughly about 10mm in diameter. Every eukaryote cell‚ with the exception of red blood cells due to their very specific function‚ has a nucleus. The nucleus’ function is to store DNA‚ it does so in two ways: One is tightly packed and this is called heterochromatin‚ this isn’t read. And the other is loosely packed‚ named euchromatin. Euchromatin is the actively read material

Phagocytosis in Tetrahymena Does Cigarette Extract Alter the Rates of Food Vacuole Formation? Amber Ellis 11/20/2014 Bio 1130 50 Jennifer Dubberke Abstract Does Cigarette Extract Alter the Rates of Food Vacuole Formation? The objective of the experiment is to visualize tetrahymena cells and vacuole formation‚ quantify tetrahymena and vacuole formation over a defined time period. Also‚ investigate if cigarette extract alters the rate of food vacuole formation. The materials needed in completing

Learning about Cells. First thing I want to show you is two beautiful pictures of a Cell. Imagine all of this is in something so small we cannot see it with our naked eyes. About 10‚000 average-sized human cells can fit on the head of a pin. There are a few exceptions‚ but the average cell is very tiny. Here are a few beautiful examples of a cell structure to kind of give you an idea of its beauty‚ and how they fit together. Plasma Membrane (cell membrane) First we are going to learn about

Top of Form . The Male Reproductive System > The Male Reproductive System: Introduction The male reproductive system is composed of the testes‚ genital ducts‚ accessory glands‚ and penis (Figure 21–1). The dual function of the testis is to produce spermatozoa and hormones. The genital ducts and accessory glands produce secretions that‚ aided by smooth muscle contractions‚ conduct spermatozoa toward the exterior. These secretions also provide nutrients for spermatozoa while
