1. Why do you think the roots of plants are good for studying Mitosis? In my biased opinion, I believe that the roots are suitable for studying mitosis because plants always undergo mitosis. 2. Why does the root tip of the onion need to be stained? The root tips of the onion need to be stain because they provide more visibility when looking under a microscope. 3. How many phases are in the Cell Cycle? There are five stages of the cell cycle which would be Interface, Prophase, Metaphase,…

Experiment: Interspecific Competition (Buckwheat v. Oats) I. Introduction Understanding relationships between organisms is crucial to the study of ecology. Within the study of organism relationships, there exist many types of ecological competitions. The focus of our lab experiment will be on interspecific competition. Interspecific competition is best defined as the competition between individuals of different species (Brooker et al 2014). The concept of interspecific competition is…

of all biology emanates from evolution, as the great evolutionary biologist Theodosius Dobzhansky once said "Nothing in biology makes sense except in the light of evolution"(1973). Therefore, studying the phylogenetic relationships of different organisms offers numerous advantages that go well beyond those of just pure research. Modern scientific literature states, that the last common ancestor of vertebrates and invertebrates had muscle. Additionally it is also well documented that most…

Viruses are particles that depend on a host cell they infect to reproduce and carry out metabolic functions. They are considered both living and nonliving. Viruses reproduce and mutate, therefore they can be considered living. However, they also lack organelles and cytoplasm, which is characteristic of a nonliving particle. Most viruses contain either DNA or RNA enclosed in a protein coat called a capsid, and upon infecting a host it induces the host cell’s replication machinery to reproduce. A…

the ways of life. Taking the smallest thing like a cell has the power to change everything. The cell’s power can be used for good or for bad. Cells have the capabilities to cure the most invasive diseases. Us humans, for instance, is such a complex organism cell growing, reproducing and then dying and starting all over again. Sometimes there are issues that cause things to go wrong. I suffer from Psoriasis. Psoriasis is a…

EA & JB 2 Identifying Neisseria sicca INTRODUCTION Bacteria are microorganisms constituting a large domain of prokaryote. They are typically a few micrometers in length and have a number of shapes ranging from spirals to rods and spheres. Bacteria are known to be among the first forms of life to appear on Earth, and are present in almost all habitats. They inhabit water, soil, radioactive waste, acidic hot springs, and Earth’s crust…

The study of microbiology requires not only understanding the microscopic organisms, but also the understanding of lab techniques and procedures used to identify, control, and manipulate microorganisms. The identification of microorganisms is not only important in microbiology lab, but also in the medical field to identify an agent of a disease that will help treat the patient by using the correct antibiotics to kill off the host. In this unknown lab report, techniques and procedures learned in…

fundamentally interconnected with other living organisms. Humans aren’t just connected in the larger sense of the planet, says Thomas, but also at the cellular level. Thomas argues that human survival wouldn’t be possible without the help from the microscopic and independently acting organisms that are present in the human body. Organisms such as mitochondria and bacteria are relied on by humans, just like other living things depend on other organisms in a similar manner. Thomas notes that…

Your packed lunch encased in plastic, the field of corn you pass on your way to work, and everyone’s favourite web-slinging superhero. All three have something in common, and it's more common than you might think. Every one of these things have been manipulated by humans at the lowest level we can, while still calling the science we used biology and not chemistry. We are of course referring to genetics, or more accurately, Genetic Modification and Engineering. To the uninformed and naive, any…

decades. Modifying DNA has had benefits for years including creating insulin and making bacteria that cleans up oil spills. We have been consuming it since 1994 when Flavr Savr tomatoes, were approved to be sold in grocery stores. Genetically Modified Organisms have been around for a while now, which is why buyers should have the right to know what is in their food. Genetically mortified food is food that scientists have taken into a lab and finagled with the genes to either add or take out…
