Poison

       Arsenic is a natural semi-metallic chemical that is found all over the world in groundwater. They can also be found in tocks, soil, air, plants and even animals. One of the main catches that makes it very dangerous is that it has no taste or even smell and it can even be found in its pure form in steel gray metal. Arsenic Poison can be caused by the ingestion, absorption, or inhalation. If it is not treated it can can cause many health complications, one of those being deathArsenic was used as a In some cancer treatment arsenic has been useful and in some  studies its shown to send the disease into remission and help to thin the blood. The treatment is actually still being test but they hope for it to be more promising in the future. One of the main causes of arsenic poisoning world wide is the groundwater that people are drinking. It contains high levels of toxins and the water becomes contaminated by the rocks that release arsenic. 

There are different types of symptoms just depending on the amount or way the arsenic is actually ingested. If the poison is ingested orally then within thirty minutes the first symptoms to appear are:
~drowsiness 
~headaches 
~confusion 
~terrible diarrhea 

Now is the arsenic is inhaled or a less concentrated amount has been ingested then the symptoms are most likely to be different and take longer to emerge. The patient that had taken the arsenic poison may start to suffer convulsion and their fingernail pigmentation may change also known as leakonychia. In more severe cases some of the cases could include:
~metallica taste in mouth
~mouth produces extra saliva
~problems swallowing
~blood in the urine 
~cramping muscles 
~loss of hair
~stomach cramps
~convulsion 
~excessive  sweating
~breath smells like garlic  
~diarrhea
~vomiting

Cell Structure Project

My group and I had created a cake to represent a cell. We used many different types of candy to represent what each and everything is on the cake. There were little toothpicks on each one to label what they are. If you click on this link it will take you to my photo-bucket  This is where I put all the pictures of the cake, so you can go there and see our cake. 
Rough ER- The endoplasmic reticulum is an organelle of cells in eukaryotic organisms that's forms an interconnected network of membrane vesicles.

Cell Membrane- the semipermeable membrane surrounding the cytoplasm of a cell.

Ribosome- a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells.

Nucleus- the central and most important part of an object, movement, or group, forming a basis for its activity and growth. 

Nuclear Membrane- also known as the nuclear envelope, nucleolemma or karyotheca is the double lipid bilayer membrane which surrounds the genetic material and nucleus in eukaryotic cells.  

Nucleolus- a small dense spherical structure in the nucleus of a cell during interface.  

Golgi Body- is made up of several layers of fluid-filled membrane sacs stacked like pancakes. The purpose of Golgi body is to sort and transport proteins within a cell.

Cytoplasm- the material or protoplasm within a living cell, excluding the nucleus.  

Mitochondrion- an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur

Vacuole- a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
Lysosome- an organelle in the cytoplasm of eukaryotic cells containing derivative enzymes enclosed in a membrane

Microscopy Lab

 


My group and I were not the brightest because we didn't exactly take picture of the different things we used the microscope on. Instead we decided to draw them out. We were all able to learn how to use the microscope correctly and practiced on different types of slides. There are a few pictures of the drawings that we were able to use below.
