Plant Cell
Plant Cell
Plant Cell I am your usual plant cell. There are trillions of my kind on all plants, grass, and trees. My breed ranges from ten to a hundred micrometers. I am approximately twenty micrometers since I dwell in grass. My organelles stretch out to one to ten micrometers. If you are asking what I really do and how I live, I am going to answer them in this paper. First off, any cells requires a structure, metabolism, energy, nutrients, waste, and communication. I am more complex than most other cells
Bacteria
Bacteria
Bacteria Bacteria are often maligned as the causes of human and animal disease (like this one, Leptospira, which causes serious disease in livestock). However, certain bacteria, the actinomycetes, produce antibiotics such as streptomycin and nocardicin; others live symbiotically in the guts of animals (including humans) or elsewhere in their bodies, or on the roots of certain plants, converting nitrogen into a usable form. Bacteria put the tang in yogurt and the sour in sourdough bread; bacteria
THE BUBONIC PLAGUE
THE BUBONIC PLAGUE
THE BUBONIC PLAGUE Rana Kundu Introduction Plague, was a term that was applied in the Middle Ages to all fatal epidemic diseases, but now it is only applied to an acute, infectious, contagious disease of rodents and humans, caused by a short, thin, gram-negative bacillus. In humans, plague occurs in three forms: bubonic plague, pneumonic plague, and septicemic plague. The best known form is the bubonic plague and it is named after buboes, or enlarged, inflamed lymph nodes, which are characterist
Scarlet Letter
Scarlet Letter
Scarlet Letter Hester's Devotion The Romantic movement in American literature greatly expanded the love story genre. In Hawthorne's novel The Scarlet Letter he writes of adultery in a Puritan village. The story deals with the relationship between Hester Prynne, a young bride awaiting her husband, and Arthur Dimmsdale, an inspired Puritan minister who is beloved by the populace. Do Hester and Dimmsdale truly love each other? Hester does indeed love Dimmsdale, but the love is not returned by the p

Plants Life science 7th grade Jr high Chapter 1 Plants are the basis of the food pyramid for all living things, even other plants. They have always been very important to people, not only for food, but also for clothing, weapons, tools, dyes, medicines, shelter and a great many other purposes. Both humans and animals benefit from plants. We eat many different types of plants such as fruits and vegetables. We also use plants for our herbs. Plants are also used to manufacture many different produc

The Plant Cell
The Plant Cell Cell Wall Size: Around 1? Basic Function: * Hold the shape of the cell. * Strengthen the cell. Covering the cell membrane of the plant cell, there is the cell wall. The cell wall is composed of two layers of rigid, hard cellulose embedded in compounds like pectin and lignin. Pores in the cell wall allow molecules to pass through. The cell wall has two parts. The primary cell wall is formed during the growth of the cell. After the cell has stopped growing, a secondary cell wall for
Animal Behavior
Animal Behavior
Animal Behavior Biology lb Abstract Animal behavior is predictable. Their behavioral tendencies are influenced by the relationship of its anatomy to their environment. By observing various forms of life, and associating the mechanism of their abilities to perform a behavioral action, evolutionary influence thereafter, can be analyzed and deduced from that point. Introduction The science and study of animal behavior involve an enormous array of complicated factors. For instance, stereotyped respo
Active Transport
Active Transport
Active Transport Since the cell membrane is somewhat permeable to sodium ions, simple diffusion would result in a net movement of sodium ions into the cell, until the concentrations on the two sides of the membrane became equal. Sodium actually does diffuse into the cell rather freely, but as fast as it does so, the cell actively pumps it out again, against the concentration difference. The mechanism by which the cell pumps the sodium ions out is called active transport. Active transport require

Polygraphs Introduction Homo Sapiens have yearned for a reliable and consistently correct way of finding out if one is telling the truth since ancient times. ?Early societies used torture. Statements made by a person on the rack were considered especially believable.? (Jussim, pg.65) There was also trial by ordeal, which was based on superstition. For instance, if there were two suspects for one crime, it was thought that the innocent would be stronger in combat and thus vanquish a guilty oppone
Nitrogen
Nitrogen
Nitrogen Nitrogen, symbol N, gaseous element that makes up the largest portion of the earth's atmosphere. The atomic number of nitrogen is 7. Nitrogen is in group 15 (or Va) of the periodic table. Nitrogen was discovered by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist, Antoine Laurent Lavoiser about 1776. Nitrogen is a colorless, odorless tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can be compressed into
Acid Rain
Acid Rain
Acid Rain Acid rain is a serious problem with disastrous effects. Each day this serious problem increases, many people believe that this issue is too small to deal with right now this issue should be met head on and solved before it is too late. In the following paragraphs I will be discussing the impact has on the wildlife and how our atmosphere is being destroyed by acid rain. CAUSES Acid rain is a cancer eating into the face of Eastern Canada and the North Eastern United States. In Canada, th

Concepts of Lifetime Fitness September 1, 1997 Homeostasis is the state of equilibrium in which the internal environment of the human body remains relatively constant. Two excellent examples of homeostasis are how the body maintains a constant temperature and blood pressure during strenuous physical activity or exercise. Although there are many other activities in the body that display homeostasis, I will only discuss these two. Temperature in the human body is usually kept at approximately 37 d

All Chordates shared four major characteristics; a notochord, which provides a skeletal support, a dorsal hollow nerve cord, which develop into the central nerve system, pharyngeal slits, which are openings in the pharynx that develop into gills, and a post-anal tail. Organism 2,7 and 8 are the phylum Mollusca. The animals in this category share many characteristics which are bilateral symmetry,two cell layers, tissues and orga

What could be the causes of this tingling sensation?
1. What could be the causes of this tingling sensation? Tingling is a common symptom of anxiety. The patient is probably over breathing which is a form of hyperventilation which means that the person is breathing too shallow or breathing too quickly or too much and from his chest rather than his diaphragm without realizing it. A person can hyperventilate himself without realizing he is doing so. 2. What are the various patterns of respiration and their significance? Fig. Four types of breathing
Enzymes
Enzymes
Enzymes Competitive Inhibition competitive inhibition. Fake substrates competing with real substrates for the opportunity to bind at an active site (hence the name competitive) slows or stops enzyme function. Fake substrates look like real substrates to an enzyme\'s active site; they are, in essence, \'look-a-likes. Competitive inhibitors bind the active site of an enzyme, preventing a real substrate from binding and a product from being formed. Competitive Inhibition Competitive inhibition can
