Explanation:
ANSWER:
Most types of cancer are believed to begin with a random genetic mutation. This is followed by mutations, which endow the cancer cells with properties allowing them to grow without normal controls to become a tumor.
Mutation is any change in the DNA sequence of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment.
Genetic Mutations that lead to cancer cell formation can occur in two forms:
1. GROWTH-PROMOTING GENES are commonly mutated in cancer cells, becoming SUPER-ACTIVE and producing cells that are too strongly stimulated by growth receptors.
2. Mutations can INACTIVATE the genes that suppress cell proliferation or those that signal the need for apoptosis. These genes are known as TUMOR SUPPRESSOR GENES.
“It is not always possible to find or buy organic fruits and vegetables in today's conditions. In order to purify pesticide residues in foods, the first thing that is usually done at home is to put these foods in vinegar water. However, vinegar water is not effective in reducing pesticide residues, but in reducing the microorganism burden. Studies have done that vinegar water increases the effectiveness of pesticide residues even more. The main purpose of adding vinegar to the washing water is to create an acidic washing environment and to remove the potentially harmful biological factors that can be found on the food in case of inadequate washing. However, many of the pesticides commonly used today cannot be removed from the food due to insufficient washing and are taken into thBe body. This causes pesticides to continue their harmful effects for long periods of time.
<span>The independent variable is the only factor in the experiment that the scientist will change. The effect of the changes in this independent variable in regards to the effect on the dependent variable/s are then observed, and the outcome of the experiment will then be determined from this.</span><span />
