system diseases Gene therapy is a controversial subject sounds easy treatment. In many of ways it is, on a broader spectrum, but in your cells, it can be a little invasive. In gene therapy, doctors are basically editing the DNA content of a living organisms. Using vectors, which are genetically engineered retro-viruses; ironically, used for infecting human cells. The retrovirus is a DNA used to reconstruct mutation and make it function appropriately. It was first used on a young girl named,…

The Habit Loop In his book The Power of Habit (2012), Duhiggs explains “this process within our brain is a three-step loop” (p. 19). That is, the three essential components that make up this ‘habit loop’ are as follows: a cue, a routine, and a reward. Beginning with the first step, a cue is a trigger that overrides the brain to enter an automatic and involuntary mode, before determining which habit to carry out. In this case, an alarm clock going off would be the cue. Clearly, the blaring alarm…

medical professionals who specialize in aromatherapy with pharmaceutical laboratories that elaborate specific formulas. Respiratory tract Essential oils are volatile particles, that is, they evaporate. When they are inspired, they penetrate the organism through the pulmonary alveolar reaching our bloodstream. The speed and efficiency with which they are incorporated depends on many factors such as the intensity of respiration, the amount of oxygen we have in blood, or the specific…

Molds are multi- or unicellular while yeasts are unicellular in structure. Molds grow in the form of tangled mass called the mycelium which is composed of filamentous hyphae while yeasts are spherical or oval-shaped. Molds are colourful while yeast are colourless. Molds can reproduce through small spores sexually or asexually while yeast reproduce asexually by budding or binary fission through mitosis in which a nucleus is divided into two or more nuclei. Mould can grow on food with low pH…

B) Compare & contrast: Plant & Animal cells. Although plant and animal cells contain numerous similarities, they also feature prevalent significant differences. Animal and plant cells not only have functional differences but also have structural differences. Plant and animal cells both have a nucleus which is the control centre of the cell, it controls how the cell develops and how it reproduces. DNA is the genetic makeup of a cell, organ and body systems, the DNA in a cell is held and…

cloning, Reproductive cloning and Therapeutic cloning these two are very different. Reproductive cloning is when you need a surrogate mother and Therapeutic cloning is when you remove the nucleus from an egg and replacing that with DNA from another organism. Therapeutic is the most secure way to go since reproductive cloning has never been done before. On the other hand, therapeutic cloning is something we’ve done in the past so we can improve the things we didn’t know before with our more…

the similarities to other common pathogens. When trying to detect Kocuria rosea the results were delayed for more than a week due to growing requirements. The bacterium grows best in temperatures 25-35 degrees Celsius and is strictly aerobic. The organism can also be found in soil, water, and on the skin. It has a smooth look and a pink color. It is identified in the lab by conventional test. The results are the same as what I received in lab with the addition on being gram-positive,…

Bacteria” by Bonnie Bassler, she talk about bacteria and how they operate together to do things. She starts by stating bacteria is the oldest living component on earth, they have been here for billions of years. Bacteria are single celled microscopic organisms with one strand of DNA. Their life includes consuming nutrients from their environment, growing, and then dividing into two cells. Bacteria are continuously growing and dividing. Bassler continues her discussion of bacteria by…

Terrorist groups and armies can develop more powerful biological weaponry. The weapons can be resistant to medicines, and can target at people who carry specific genes. The genetically engineered organisms that are used for biological weapons have the capacity to reproduce faster, and this will create larger quantities in the four shorter periods of time. This implies that the level of devastation is likely to increase as well. A lot of uncertainties…

modern biological classification. Chapter 2: Body Parts (cont.) There are three types of symmetry: radial symmetry, bilateral symmetry, and asymmetry. Animals with radial symmetry have no right or left sides, only a top or bottom (usually marine organisms). Animals with bilateral symmetry with a line of symmetry dividing their body into left and right sides have a top and bottom along with a top and bottom (all true animals are bilaterally symmetrical except those that are radially…
