The cell wall is the tough‚ flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection. Just as the wall of the factory is for the factory. The wall also is the structure and strength. The cell membrane that separates the interior of all cells from the outside The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances

Diversity can bring one another together‚ to unite all culture and races together as a whole. It recognizes people with different backgrounds‚ skills‚ attitudes‚ and experiences and they can bring fresh ideas and perceptions. Diverse societies encourage and harness these differences to make a society or communities more approachable to different people. It brings people views and experience to be listened to and to help meet the needs that are needed to make a change. Diversity can be seen

Blood Cells Leukocytes (WBC’s) Leukocytes also known as white blood cells (WBCs) are cells which play a defensive roll in the body against injury and infection. They migrate towards tissues where they are needed and become functional performing various activities. WBCs can be divided into 2 groups: Polymorphonuclear granulocytes and mononuclear agranulocytes. Both types are spherical while suspended in blood plasma but when they invade tissues after leaving the blood vessels they become amoeboid

Cell City Cell City A cell is like a city. They both have parts that play different roles. A cell is microscopic that has organelles‚ and a city has different services. Keeping them both running smoothly and orderly. As a result they both survive and grow. There’re a lot of different organelles in a cell that are similar to a city for example the cell membrane borders and protects the cell it’s role is letting certain things in and out of the cell in the same way a border in a city does.

Cell Theory In biology‚ cell theory is a scientific theory that describes the properties of cells‚ the basic unit of structure in every living thing. The initial development of the theory‚ during the mid-17th century‚ was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory states that new cells are formed from pre-existing cells‚ and that the cell is a fundamental unit of structure‚ function and organization in all living organisms. It is one of the

almost expected that a couple will live together without marriage. Cohabitation‚ once rare‚ is now the norm. Filipino family life has changed drastically as marriage is losing ground and more couples live together without tying the knot. Instead of using terms such as ‘husband and wife’ or even ‘spouse‚’ businesses and advertisers speak of ‘partners’ and ‘companions’. Instead of getting married‚ couples talk about being together. Couples who live together without marriage are called ‘domestic partners’

Kierra Roberts 1-4-11 11B How Do Batteries Work? Electricity is the flow of electrons through a wire‚ that is called a circuit. Batteries have three parts to them‚ an anode‚ a cathode‚ and an electrolyte. The cathode and the anode are hooked up to an electrical circuit. The chemical reaction that is happening causes the electrons to build up at the anode. When the circuit is closed the electrons will be able to get to the cathode. When the electrochemical process change the
