Give an example of how scientific naming is important to the study of medicine
|
In medicine they use Latin which is a dead language and non-changing. Also, it is used around the world so if you get sick in another country it is called the same thing. Medications are as well. So, Latin is a universal language.

|
A pandemic is when a particular disease is prevalent across the world. There has been a lot of talk about a possible pandemic of the "Bird Flu". With all of modern technology and medical advancements, hypothesize how a disease like the "Bird Flu" can affect the entire globe.
|
In a country like ours with our modern medicine this would be able to be treated very easily. However, in other countries many people will die because they don't have the modern technology. This would be similar to any diease, example is AIDS. In our country it is more treatable and people can live long lives with HIV because of the medications that have been developed to help it. In other countries where medicine is not there and the advancments of mecidine and technology is not present the diease is still an extremely serious issue and is still spreading and people are still dying from it. The "Bird Flu" would be the same type of thing.

|
You are walking along in a park and notice an unusual organism. It is not moving, but is appears to be attached to the side of a tree. After viewing some of its cells under a microscope you notice it is multicellular with eukaryote type cells. No chloroplast is present. To what kingdom does this organism belong?
|
Fungi Kingdom
|
|
|
Tongue Rolling is a dominant characteristic. If you cannot roll your tongue you have two recessive genes for tongue rolling. If one parent is heterozygous for tongue rolling (Tt) and the other can not roll their tongue (tt), what is the percent chance that the offspring can roll their tongue?
|
Tt would mean that you can roll your tongue, so it would be 50% chance.
|
|
|
Evaluate the following: As DNA technology increases, will health insurance companies be able to use genetic screening to deny coverage to anyone whose genes aren't in perfect working order?
|
I personally could see this happening in the future. You already have health insurance companies that deny people for pre-existing conditions now. So, with that thought in mind this could be something that could happen in the future. If your DNA shows your child could have some diease then they could tell you to find another provider.
|
|
|
Using your knowledge of meiosis, justify how there are so many varied phenotypes within a species such as humans
|
There are two different ways species genes can be assorted. The first would be by crossing over. This is where half of the species chromonsomes would cross over onto the member of a pair of the chromosome giving more differences. The second would be by Independant Asortment. This is where 4 alleles occupy the same cell. Also, you can half random fertiliation
|
|
|
Name one way mitosis and meiosis are alike and one way they are different
|
Difference - Mitosis produces 2 new cells and Meiosis produces 4 new cells.
Alike - They both produce new cells |
|
|
Should scientists use cloning to help save endangered species? Give two reasons to support your opinion
|
In my opinion scientists shuld use te cloning to help save endangered species.
1) we need to help preserve the live of the species and we need the plants and animals to live. 2) Diversity of live is important and we learn from watching the other animals and species. Humans is one of the causes for the animals extinction. We use plants and animals for medications and foods. |
|
|
Compare and contrast Photosynthesis and Cellular respiration. You must include two ways they are alike and two ways they are different
|
Photosynthesis is complex process by which carbon dioxide, water and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using the energy from the sun and chlorophyll
Cellular respiration is oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis absorbes the suns light and gains energy and Cellular respiration is cells regaining energy from oxygen that is breathed in. They are alike by 1) Both provide power for cellular activities 2) Both utilize ATP for energy at some points They are different by 1) Cellular repiration depends on oxygen 2) P:hotosynthesis involves CO2 and H2O as substrates |
|
|
What cellular process causes a cell to become cancerous? List three possible causes for cancer
|
During the S phase of interphase the prepartion for mitosis occurs. Mitosis is the procss by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets. Errors in miotosis can either kill a cell through apoptosis or cause mutations that may lead to certain types of cancers.
Possible causes for cancer 1) Sun exposure UV rays- Skin cancer 2) Smoke and tobacco products 3) Environmental causes such as asbestos, pollution in the environment and even some medical test and treaments |
|
|
What are two major differences between Compound light microscopes and electron microscopes
|
Compound light
1)a beam of light that is focused using glass lenses 2) magnification is moderate Electron microscopes 1) uses a beam of electrons that is focused using magnets 2) Magnification can be vrey high and can show details that you can not see with the Compound light microscopes |
