Constructive boundaries occur when two plates move apart which causes new oceanic crust to be formed and mid-ocean ridges are created by the build-up of molten rock on the seafloor due to the mantle building up. This new crust pushes the old crust aside and forcing the plates apart at a very slow rate. Basaltic lava rises which means new crust is being added continuously. Rift valleys are formed at constructive boundaries‚ where convection current causes the crust to be pulled apart causing fractures

This experiment tested the growth of E.coli with inserted plasmid on an agar plate with Ampicillin. One colony of E.coli resistant to Ampicillin was grown during this experiment. The overall goal of the experiment was to successfully grow E.coli on the agar plate‚ which would show that the plasmid had been effectively inserted into the bacteria’s genes. This experiment helped students understand how plasmids were inserted into bacteria and used in real life situations. It also showed how the bacteria’s

INTRODUCTION Plate tectonics The large scale motions of the earth’s lithosphere are describe by a scientific theory called plate tectonics which explains that Earth’s outer layer is made up of plates‚ which have moved throughout Earth’s history. The theory was developed during first decade of 20th century (by a famous advocate Alfred Wegener) on the older concept of continental drift and was accepted by many geoscientific communities. There are currently seven major and many minor plates are present

Plate Tectonics Ever since the beginning on time‚ Humans believed the ground is solid and immobile. But this is not true whatsoever. The Earth is every-changing and continually in motion. The stability of the Earth is not at all what we think it is. Thinking about the rotational axis of the Earth‚ and possibly of what the Earth may become at a certain point in time‚ has a great influence on understanding all aspects of living things‚ either in the past‚ present‚ or future. The study of Plate

Lab 11 Methodology By using aseptic‚ a little cultured bacteria was inoculated on the TSA agar. A quadric streak was making. Inoculation loop was heated and keep it cold for a while before the next quadratic streak. Six agar plates were observed for 24 hour at temperature of 30ºC. Choose one from the dense colony and make a sub-culture on the new agar plate. The step was repeated to get a single colony‚ which is pure colony. a) Sequestration of bacteria from fish organs Methodology

sterilizing it with 70% ethanol. Then trypticase soy agar (TSA) was poured into six groups of 60 Petri dishes (See Appendix 1). The dishes were labeled based on the antibiotic used and were left to dry and solidify at room temperature. After an hour‚ the dishes were placed in a refrigerator at three degrees Celsius. If there was visible condensation on the agar plate‚ they were flipped to avoid the contact of heat that drove the moisture out of the agar dishes. The contents of the broth culture of E.

Lab: Plate Tectonics Goals of this lab: -to learn about types of Plate Boundaries -to learn about Plate Boundary Interactions -to familiarize yourself with the Plate Tectonic Map of the World -to understand and familiarize yourself with past Plate Movement and the supercontinent Pangea -to understand the Hot Spots of Hawaii and Yellowstone Part 1. Types of Plate Boundaries There are 3 types of plate boundaries and a fourth called a “plate boundary zone” in which the type of plate boundary

Plate boundaries Plate Boundaries is a theory of the global movement over a period of time. There are three main types of plate boundaries they are‚ transform boundaries‚ convergent boundaries‚ and divergent boundaries. Transform boundaries are where two plates are sliding past each other. These areas are also known as faults. Most transform boundaries are found on the ocean floor‚ a few however are found on land. Since these boundaries do not crunch together they to not tear or break
