...6.Distilled water sample is necessary in procedures A and B because it is used as a control sample. Distilled water is used as a control because its purified. Its devoid of contaminants. Controls are needed so you can see what the results would be of an experiment. Positive controls tell you what the positive result of your unknown would be, and negative controls show you what the negative result of your unknown would be when added with Benedict's solution or the Iodine solution. Without the controls, you wouldn't know. Lipids 1.Fat molecules are made up of a molecule of glycerol and three molecules of fatty acids. Each fatty acid consists of a hydrocarbon chain with a carboxyl group at one end. The glycerol molecule has three hydroxyl groups, each label to interact with the carboxyl group of a fatty acid. Removal of a water molecule at each of these three positions form a triglyceride. 2.Fats, oils and waxes are all lipids. Fats and oils are made from glycerol and three fatty acids joined by dehydration synthesis. (also known as triglycerides). Naturally occurring esters of long chain carboxylic acids with long chain alcohols are waxes. Waxes are low melting point solids. 3.A diet including large quantities of saturated fatty acids should be avoided because saturated fatty acids are a major risk factor for heart attacks and strokes. Diets high in saturated fatty acids lead to an increase in the production of cholesterol. They also lead to health problems......

...Cell Structure and Function Lab Drawings: Draw 1 cell at high power and label parts as given in directions. Elodea leaf cells (400X) Stained Onion Cells (400X) [pic] Stained Cheek Cell (400X) Stem Cell (from pictures) Lab Summary 1. “Plants and animals obtain food in different ways.” What microscopic evidence did you see to support that statement? Plant cells have chloroplasts and organelle that can produce food. Animals do not. 2. Did the iodine solution aid in your observation of onion cells? Why do biologists use stains to study cells? Yes, the cytoplasm and the nucleus were much easier to see. Stains allow parts of the cell to be seen more clearly. 3. What microscopic structure shows that the onion cell is a plant cell? The cell wall 4. What structures can be seen in an unstained onion cell? The cell wall 5. What structures can be seen in a stained onion cell? The cell wall, cytoplasm and nucleus, (maybe the cell membrane) 6. In what ways are Elodea cells different from onion cells? What organelle does Elodea have that the onion does not? Why might this be so? The Elodea has chloroplasts and the onion cells did not. The onion cells that we were looking at are found below ground where the sun doesn’t shine; therefore, chloroplasts are of no use to them. If I had given you the leafy part of the onion, you would have seen chloroplasts. 7.......

...that starts the “chain reaction” which ends with the entire operating system being loaded is known as the boot loader (or bootstrap loader). The term creatively came from early designiners imagining that before a computer “runs” it must have it’s “boots strapped”. The boot loader’s only job is to load other software for the operating system to start. Often, multiple-stage boot loaders are used, in which several small programs of increasing complexity sequentially summon one after the other, until the last of them loads the operating system. Boot Devices The boot device is the device from which the operating system is loaded. A modern PC BIOS (Basic Input/Output System) supports booting from various devices. These include the local hard disk drive, optical drive, floppy drive, a network interface card, and a USB device. Typically, the BIOS will allow the user to configure a boot order.

...Question 3 a). The needles are arranged vertically pointed up, outwards, and are stuck close to one another; attached in clusters. b). In a bundle, there are two leaves in a bundle. c). Pine leaves have needles, instead of flat leaves, like the broad-leaved trees. The needles help to survive winter’s hardship. For example, the needles cut evaporation so trees can save water, which is very useful during the winter season. Broad leaves trees, produce new leaves every spring. Photosynthesis occurs rapid in broad- leaved trees, unlike the pine leaves. d). Pines are called evergreens because the tree does not shed its leaves during the fall, they stay green all year around. e). Pine roots and fir are some plants that we’ve studied in the lab that are evergreen. f). Function: • Resin duct: secrets resin to protect pine needle plants from insects and other animals that try and eat it. • Stoma: tiny openings which allow gas exchange necessary for cellular processes; photosynthesis. • Epidermis: It protects against water loss, functions in gas exchange; oxygen and carbon dioxide, and helps keep its structure. • Photosynthetic...

...DNA, one of the most important molecules of all living organisms, holds the genetic imformation that determines the strucure of proteins of every individual organism. Being used in millions of organisms, those living and non-living, DNA can be formed in almost an infinite amount of combinations, making millions of unique traits. DNA has been used in the organisms living on the Earth since the beginning of life, about three or four billion years ago. The search for the chemical identitiy of genetic material started more than a century ago. Im 1869, a method was publshed by Swiss scientist Frederick Miescher on how to separate the cell nuclei from the cytoplasm. In doing that, an acid material was extracted from the cell nuclei which Miescher called "nuclein". Later on, nuclein, which was now called nucleic acid, was found to be involved with different proteins formed in combinations called nucleoproteins. Each nucleotide is made up of a sugar moiety, a phosphate group, and either a purine base or a pyrimidine base. The sugars that had five carbons was given the name ribose whlie the sugar lacking on oxygen atom was givn the name dioxiribose. Since no nucleic acid can contain both of these sugar, there are two types of nucleic acid: ribonucleic acid (RNA), and deoxiribose nucleic acid (DNA). In the 1950, the structure of DNA was cleared with the help from chromatographic separation and X-ray studies. From that it was established that DNA generally is in the form as a duplex...

Filter feeding is the filtering of nutrients and plankton suspended in water therefore for sponges to feed effectively they must be aquatic ! !
