plain leaves and not the striped leaves. It doesn’t eat the striped ones because it knows that a clover that can produce cyanide is striped and therefore poisonous, so it tends to stay away from it. That’s why the snail didn’t eat the clover the plain leaf that was painted with white stripes. From the wild it knows not to eat striped leaves. It’s pretty much like a visual warning. Exercise 3- Important factors for plant fitness are, elevation, average yearly precipitation temperature, and presence

Water potential is often represented by the Greek letter, psi ψ .The higher the rate of collisions of the water molecules with the membrane, the greater the pressure on it. This pressure is called water potential. Water always moves from higher water potential to lower water potential. The standard unit for water potential is kilopascals (kPa), which is also the unit pressure. Pure water is designated a water potential of zero which has the highest water potential under atmospheric pressure at 25°C

the plant is losing too much water the guard cells close to stop that. Most stomata are on bottom of the leaf. Also by looking at the number of stomata a lot of information can be predicted about a plant. So for example, plant that has a high concentration of stomata shows fast growth and wet

trees change color in autumn? This paper will explore various pigments,carotenoids,chlorophyll,anthocyanins,xanthophylls and how those pigments are responsible for various activities of trees. The hypothesis of this project is “If the type of leaf is a oak leaf, then the number of pigments will stay the same.” The idea for this science fair project is to collect three different types of tree leaves and count the number of different types of pigments in each. This project should be interesting because

Love in the Forest “A little girl was driving home her cow, a plodding, dilatory, provoking creature in her behavior, but a valued companion at that” (Jewett). Sylvia’s attentiveness to the wellbeing of the cow speaks to her care for animals; the creatures of the forest trust her and come to eat food from her hands. Cruelly, an intrusion into the way of life that Sylvia has made for herself tests her connection and dedication to the natural world. In Sara Orne Jewett’s short story “A White Heron

characterized by sporangia with a vertical annulus stopped by the stalk and stomium. Licorice Fern are placed into the family Polypodiaceae, meaning they contain sporophytes that have creeping rhizomes that sometimes produce pinnate leaves. The rhizome and leaf axis have multiple vascular bundles arranged in a circular pattern. Another distinctive feature of the Family are small, lens-shaped sporangia that create continuous sori. Its genus is Polypodium, comprised of epiphytic ferns with creeping rhizomes

plus as you can see through the design of the fence. • The design that is used in creating chain link fencing makes it a good choice for temporary use. You can pull chain link fencing out from the ground, roll it up and then move it to a different spot. • Before installing a chain link fence, check with your local building department, regarding local zoning

defining them. During the summer, chlorophyll dissolves in the heat and light, but it is also being steadily replaced. In the fall, on the other hand, no new pigment is produced, and so we notice the other colors that were always there, right in the leaf, although chlorophyll’s shocking green hid them from view” (Ackerman 542). This quote explains the process of the coloration of the leaves. She also compares the difference of how chlorophyll acts during the fall and

PROCCESSING OF FINDINGS The average height of an ostrich fern is between 1 metre and 1.82 metres (Croft)and the heights of all the ostrich ferns were within the same range (shown in figure 1). Results of the height of the ferns after the experiment had been conducted and were then tabulated into the experimental group and controlled group rows. The results also show the height difference each fern underwent from the beginningend of the experiment. Average results were shown for both the controlled

“Object, may be missile, fired from Soviet base, Anadyr Peninsular… DEW Line high sensitivity radar now has four objects on its screens. Speed and trajectory indicates they are ballistic missiles” (Frank 89). Pat Frank’s Alas, Babylon, which is based on a fictional nuclear attack against the United States by the Soviet Union, is a post-apocalyptic novel set in the early 1960’s in America during the Cold War that aims to warn people of the alarming possibility of nuclear war with the Soviets.

1. Introduction Isodon is widely distributed and important genus of the family Lamiaceae. Various diterpenoids with diverse structures had shown antibacterial, antiinflammatory and antitumor activities.1 Isodon wightii (Bentham) H. Hara is a perennial herb commonly distributed in Western Ghats, South India up to 8000 feet. Ent-kaurene diterpenoid, melissoidesin isolated from the leaves showed antioxidant, antiacetylcholinesterase, cytotoxic and anticarcinogenic activities.2-3 In vitro mass multiplication

Materials and Methods The materials used in this laboratory was the diameter tape that we used to measure the tree’s width. We were designated the middle team and at our first point we used the quadrant method, and the quadrant method is when pick our first point that we started off with and extend both our arms facing north and south respectively to form two quadrants. The quadrants are then separated in half when we extend our arms east and west. Whichever tree that is closest to the point in

It is not entirely possible to give a sufficient answer to the question ‘what is identity’. The term identity is surprisingly difficult to define adequately in the sense that it is a contradictive phrase expressing both sameness and uniqueness. Many theorists such as Erickson have attempted to answer this difficult question but rather define the process and identify influences as there is no exact definition for this complex process. The word itself derives from Latin ‘Idem’ which means identical

“The Lottery” Short Story Essay In Shirley Jackson’s “The Lottery”, Jackson displays many cases of symbolism over an interesting theme. He also shows some irony throughout his short story. His story takes place in a fictional small town around an annual lottery. However, this isn’t a regular lottery. This lottery is based on the idea of “survival of the fittest” and is put in place to keep order in society. The leaders of the town push to keep the lottery in place because of tradition, and that

The historical references in Allende's novel are particularly strong; some of her characters describe real Chilean figures. The Candidate/President is, of course, Allende's uncle, Salvador Allende. The family itself is symbolic of the nation, as Earle shows that the del Valle-Trueba family

Upon first inspection, these three Tolkien quotes arise to be not cohesive statements that appear together. “Mythopoeia” seems to be depicting the forces of good and evil; “Leaf by Niggle,” endeavors to make a claim about fate, while The Silmarillion focuses on power. While these very different statements all seem to be true on a surface level, they are unrelated to their shared theme. However, through a close reading of theses texts, these three Tolkien quotes share divine commonalities that add

In the novel The Jungle, Upton Sinclair illustrates that “Neither the squeals of hogs nor tears of visitors made any difference to [the workers]; one by one they hooked up the hogs, and one by one with a swift stroke they slit their throats” exemplifying the desensitization of workers in the meat-packing industry (Sinclair, 35). This desensitization was the result of years of tedious work that removed all hope from the workers and left them isolated. However, it is not only the nature of the work
