Biology- Animal cell The NUCLEUS is the largest organelle in the majority of cells. It contains genetic information in DNA‚ which is responsible for the cells unique characteristics. The nucleus is separated from the rest of the cell by.... ...The NUCLEAR ENVELOPE is used as a barrier which separates the contents of the nucleus from the cytoplasm‚ all in all keeping the DNA safe and intact. The nuclear envelope regulates the flow of substances into and out of the nucleus. The NUCLEOLUS is an important

Biology HL Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

“Biology Article” Barbara Manley Professor Trinna S. Johnson Introduction to Biology May 9‚ 2013 A New System for Cancer Detection This article summarizes a new technique that would allow for cancer cell detection without being invasive to a person’s body. It states that currently‚ human cancer cell detection is conducted through a person being cut on or biopsied. This new procedure allows for humans bodily fluids to be utilized in detecting cancer cells. Chandra states‚ “While current

Tertiary structure The shape of the tertiary structure is three dimensional due to the coils and pleats folding in on themselves when the protein is formed. The tertiary structure is held in place by lots of different types of bonds. A protein’s tertiary structure is vital to its function; one example would be when a hormone must fit a special type of hormone receptor of a target cell. When you heat a protein‚ the kinetic energy increase in the molecule. This causes the molecule to vibrate and

The effect of water and fertilizer on corn seedlings Biology 1108 Lab Section November 7‚ 2012 Abstract The effect of water and fertilizer on corn seedlings was examined. It was hypothesized before the experiment that enough water with sunlight and air should make the plants grow healthy. It has to do with photosynthesis. Fertilizer is also going to make the plants grow much faster; this is because of the nutrients in it. The experiment took about four to six weeks to complete; it took some
