Viruses : A Small Organisms And Most Viruses Essay

Cancer is a defined as a group of cells in the body that begin to divide without stopping and

When cells in the body start dividing and regenerating uncontrollably, they lead to cancer – and this is true for all the cells in the body. If the cancer is not nipped in its bud early on, it can spread to other parts of the body. This presents the common question asked regards cancer; how can it be stopped early on? The same can be said for cancers that start from the bone marrow such as multiple myelomas.

Cancer is where abnormal cells divide uncontrollably and destroy tissue. With each special type of cell through differentiation each cancer is unique like Leukemia and breast cancer.

Cancer starts with the normal cells in our bodies. Normal cells divide in processes called Mitosis and Meiosis which is how our bodies grow, heal and repair and when cells become old or are damaged, they die and new cells are created. However, when this cell division process goes wrong the cells become abnormal. Cell abnormalities occur when the cell makes errors whilst copying the genes. As the cell becomes more abnormal, the old and damaged cells do not die when they are supposed to but the new cells, that are supposed to go in place of the dead cells, are still produced. The extra cells divide uncontrollably which is how a tumour is formed.

Cancer is given to a whole collection of related diseases. Cancer cells begin to divide unregulated and spread into surrounding tissues. Scientists have proposed that lots of SP2 protein may transform to normal cells into cancer cells. In addition, the deprivation of specific co-stimulated molecules can impair the natural killer cells ability and lead to the cancer. Cancer occurs almost anyplace in the human body. Cells become old and become more abnormal or cells, which are damaged when they should die, divide without stopping and may constitute growths called tumors. Also cancer cells are less specialized than normal cells. The first and original tumor is called primary tumor. Primary tumor may spread to other parts of the body and create new tumors.

Cancer is a disease in the human body that is caused by the uncontrollable division and growth of cells in the body. To exist, the body goes through two processes, one called the cell cycle and the other is the regulation of the cell cycle. During these cycles, cells divide and make new cells. Checkpoints along the cycle ensure that the cells are free of any damage and that the cells all properly grow and divide as they should (Cell Division, Mitosis, and Meiosis). When a normal cell is damaged, the cell will go through a process called apoptosis and this is when the body automatically causes the cell to self destruct, unlike in a cancer cell where the cell ignores all of the signals from the body to stop the division and growth (Cell Division,

Cancer is a disease in which abnormal cells divide uncontrollably and invade other tissues; the disease can spread to other parts of the body through the circulatory and lymph systems. There are more than 100 different types of known cancer, which can be grouped into broader categories such as:

Cancer is without a doubt a scary and deadly disease to have, but is it solely responsible for killing the patient? The term cancer is a term used for a several related diseases. All cancer has the similar abnormality where cells grow at an uncontrollable and exponential rate. In a healthy person “cells grow and divide to form new cells as the body needs them” (Institute). As the cells age they naturally become damage and degrade, these damaged cells die, and new cell are produced to replace them. This is the natural process of the cell. In the case of cancer cells, these natural functions mutate and become abnormal. Instead of old damaged cells

Viruses are not usually considered living things because they lack characteristics of living things. Viruses are biological particles composed of nucleic acid and a protein coat. Viruses are not alive and should not be considered a living organism. The reasons include that a virus cannot reproduce; they do not obtain energy, and technically cannot live without a host. Reproduction is one of the biggest essentials of life. Also if an organism cant obtain or make energy it also is classified as non-living. If a virus has no host then it has no ability to reproduce or to live. Furthermore a virus should not be considered a living organism because it lacks these traits.

“Cancer”, its a disease that have claimed the lives of millions, its a disease that has not been cured, and its a disease that have many different forms. There are many types of cancer. It can develop in almost any organ or tissue, such as colon, lung, skin, bones, breast or nerve tissue. Cancer is defined as “a malignant growth or tumor resulting from the division of abnormal cells.” Some of the body cells begin to divide without stopping and spreading into surrounding issues. As cells become abnormal, old and damaged cells survive somehow when they should die, and the new cells form when they are not needed. Cancers of the blood, such as leukemias generally do not form solid tumors. These cells can divide without stopping and may form growths called tumors.

For centuries new viruses have been discovered each and everyday by thousands of different scientists. These viruses affect the lives of almost a billion people. Even though many of these viruses can be harmful to the human body, they have played a phenomenal role in the biological advances over the past century. They move DNA between species, regulate vast populations of organisms, and provide new genetic material for evolution. Viruses influence every single species on earth.

DNA viruses were thought to be the only viruses that could cause cancer because of their capability to incorporate their own unique genome into the host cell via the cell membrane. This action is a genetic alteration known as transformation. The function of DNA in a normal, uninfected cell is to control the development & operations of the cell. Therefore, when a DNA virus infects a normal cell, it has the ability to interrupt the usual functions of the cell and begin the process of mutation. Not all cells infected with the DNA virus will become cancerous. Tumor suppressor genes act to protect the host cell from becoming oncogenic.

The human body is an amazing system consisting of more than 60,000 billion cells. These cells make up the organs in our body and each cell will live different lengths of time, being about four months on average for red blood cells, and over a year for white blood cells. In order for our body to keep living, each cell multiplies into two cells before it dies. However, sometimes the cell won’t properly divide and die, which can cause many problems, including cancer.

An invisible organism enters your body. It penetrates into your tissues and then takes over the machinery in your own cells to make more copies of itself. This tiny infiltrator works silently, producing thousands of these clones that fill up the cell and cause it to explode. The clones mercilessly continue the process of invading, taking over and destroying cells. The result might be a minor inconvenience to you as the host, or it could result in a slow or rapid death. It depends only on which variant of this unwanted infiltrator overcomes your body’s defenses. There are cures to wipe out some types of these invisible intruders, but others are so difficult to eradicate or so readily adaptable, that the world’s greatest scientists

Luke stared out at the lake, it was one of the only thing not mechanical in this world besides the wild mountains were stories say that in 2020 during the war they made bunkers to house troops and supplies. But those are just stories, that was 30 years ago. Today in the 2050s everything is teched out like the hover cars and the houses, everything is wired into the central system, a huge super chip, defended by guards and laser tanks, it controls everything. My personal opinion is that something bads gonna happen and we're all gonna die. But that's just my opinion. My sister thinks that we'll be fine she's a tech genius I’m more of a sports star I’m the fastest guy on our 12 year racing team. My sister also says I also have a
