Did you know that bees are found in almost every corner of the globe and make almost all crop life through its pollination? Maybe you did‚ but we tend not to think about it very often. And by it I mean the insects. Seemingly countless bees‚ and all insects for that matter‚ stretch throughout all of planet Earth. This ridiculously large amount of insects is split up between six million and ten million different species. That’s an insane amount of variety! The Insect Fair puts this variety into perspective

ECOLOGY Ecology is concerned with the study of organisms and their habitats. This includes the interdependence of various populations‚ their impact on each other and their surroundings‚ the effect of the surroundings on their behaviour‚ as well as the ways in which the organisms and the environment change in response to each other. A pond and its inhabitants provide a good example of these interrelationships. A pond contains: a. soil consisting of rock‚ minerals and dead remains of organisms b. water

HISTORY AND CLASSIFICATION OF BIRDS The problems of classification of birds Has gained the attention of ornithologist and many systems have been proposed in order to establish their lineage until the beginning of the 19th century. The problem was solved in a rather over simplified way by using only significant characters especially external life forms and way of life and diet. Thus these birds whose toes are joined by welds where grouped in the natatoes. Those with long legs in the gralatories‚

animals have had their genes altered. A majority of these animals are mice. Scientists can now produce these animals thanks to Crick and Watson’s discoveries. A transgenic plant; however‚ has genes that have been inserted in them rather than through pollination. Benefits of these plants are that they can fight droughts‚ as well as insect resistance. Less pesticide would be used. An example of a transgenic plant is the rape plant‚ which pollinates weeds. According to google.com‚ DNA fingerprinting

Reflection: SS Chapters 6 & 7 I believe that there is much that we take for granted in our world today. One of these things we take for granted in the instant “treatment” for plants. We do so without even a second thought or consideration and continue to let it happen year after year. We also take for granted our everyday dependencies that stem from nature. I then question what it would take for us to realize our dependency on nature and to respect it as such. On page 73 of the reading‚ it discusses

Auxin Auxin are essential plant hormones that promote the lengthening of the cell‚ which is a critical step before the cell goes through cell differentiation. The auxin can do this by increasing the amount of water taken in by the cell‚ which improves the elasticity of the cell and therefore can take more water and can get increasingly longer. And don’t think for a second that that’s all auxins do auxins may have been the first plant hormone to be discovered doesn’t make it the least important

and natural fertilizer producers of nature. THEIR IMPORTANCE Humans depend on natural ecosystems of water‚ oxygen‚ sources of food and building materials‚ therefore the activities of insects in the following areas are of importance:- 1. POLLINATION: Flower color‚ shape and scent has evolved to attract their insect pollinators; e.g. bumble‚ solitary and squash bees‚ beetles‚ butterflies‚ flies and ants. 2. DECOMPOSITION & NUTRIENT CYCLING: Insects and their arthropod relatives are responsible

Gregor Mendel‚ an Austrian monk‚ contributed to the basis of modern genetics. * Mendel chose pure-breeding pea plants to study the inheritance of several characteristics. * A pure-breeding plant is obtained after many generations of self-pollination. * They produce identical offspring and the offspring show the same traits as their parents. * Table 5.1 shows the difference in meaning between characters and traits. Character | Trait | Plant height | Tall or short (dwarf) |

What One Sees Is Not Always What It Seems “Two Views of the Mississippi”‚ by Mark Twain is a very remarkable piece. In this short story he is reminiscing back to a time when he first sees the Mississippi River‚ the beauty he took in that day. Then he looks once more only to find that it is not all that enchanting. He looks back‚ only to find something that contradicts the beauty he is witnessing. When people look at something‚ they only see what they want to see‚ the truth is there is always a darker
