Cell division in animals: mitosis‚ cytokinesis‚ and the cell cycle. Cell division in animals is a two-step process involving mitosis and cytokinesis and is set up by interphase. Interphase is a growth period for the cell. In the nucleus the chromosomes are duplicated but are not yet distinguishable because they are still a form of chromatin. There is also a nucleoli‚ one or more‚ present producing ribosomes that are sent to the cytoplasm. Mitosis is the division of the nucleus and multiplication

Cell Transportation Lab Eggs are a great example of a cell. Underneath the hard shell is a thin membrane that is just like the cell membranes in your cells. There are microscopic pores in the membrane that allow substances to move in and out of the cell. Way Cool! Recall that the function of the cell membrane is to control the internal balance of the cell. It helps to maintain homeostasis. In this lab you will use vinegar‚ an acid‚ to dissolve the shell off of the egg to expose the membrane

History of the Cell Theory Ryan Strehlein Cells‚ the make-up of all living things. Some cell are complete organisms‚ such as unicellular bacteria and protozoa. Other types of cells are called multicellular‚ such as nerve cells and muscle cells. Withen the cell is genetic material‚ Deoxyribonucleic Acid (DNA) containing coded instructions for the behavior and reproduction of the cell. The cell was first discovered by the 1665 English scientist Robert Hooke‚ who studied the dead cells of cork with

Sickle Cell Anemia‚ also known as Sickle Cell Disease‚ is a disease that causes the production of abnormal hemoglobin. The red blood cells (RBCs) carry oxygen to organs and tissues. Hemoglobin‚ a molecule in the RBCs‚ is a protein that attaches to the oxygen in the lungs and carries it to all parts of the body. Hemoglobin takes on the oxygen‚ and releases carbon dioxide‚ a process known as oxygenation. In the tissues‚ deoxygenation occurs where the processes is reversed‚ when hemoglobin releases

The idea of a cell phone has been around since the nineteenth century. A cell phone is also referred to as a mobile phone‚ or a cellular device. The first cellular device was invented in 1973 by Martin Cooper. This mobile telephone was the size of a brick! Ever since this invention‚ the cell phone has become the most prevalent piece of technology. Nowadays‚ the majority of people in the world possess a cell phone. One country in particular that is very popular when it comes to cell phones is the

Over the past years there has been a hike in new technologies developed‚ and these devices have made their way into vehicles. Cell phones were first introduced in the U.S. in the mid 1980’s‚ and have since experienced dramatic growth. Cell phone use while driving should be the concern of motorists and policymakers and have lead policymakers to consider whether the use of cell phone while driving should be regulated or even prohibited. These new technologies often have people regularly engaged in multitasking
