Urinary System: Anatomy Review 1. Name the organs in the urinary system: 1. 2 kidneys 2. 2 ureters 3. bladder 4. uethra 2. The kidneys are retroperitoneal (behind the peritoneum)‚ lying against the dorsal body wall in the upper abdomen. 3. The adrenal gland sits atop the kidneys. Blood vessels enter and leave the kidney at the renal cortex. 4. The functional units of the kidney are the nephrons. They are called renal pyramids if they are located mainly in the cortex. They are called renal

Water molecules move from high to low Osmosis is what they seem to know Solute and Solvent are what’s inside The polarity of water makes it easy to find “Hyper” and “Hypo” tells you how much is there But isotonic means that they are fair Water molecules move from the inside out Scientists call this plasmolysis without a doubt All of this happens inside a membrane It is a serious matter‚ not a fun little game When a membrane is selective it chooses what it wants Few things are moved through

Introduction: Plant growth occurs throughout its life in a process known as indeterminate growth. This type of growth is capable because of the apical meristem and the lateral meristem. Meristem refers to a specialized section of plant tissue characterized by cell division and growth. Much of the mature plant ’s growth is provided by meristems in nature. And typically‚ Apical meristems found at the tips of stems and roots while lateral‚ or secondary‚ meristems found just under the surface along

Introduction “Micro” refers to tiny‚ “scope” refers to view or look at. Microscope is the major tool of biologists‚ an optical instrument that uses lens or combination of lens to produce magnified images that are too small to seen by unaided eye. Microscope provides the enlarged view that helps in examining and analyzing the image. Through the use of microscope ‚ knowledge of cell structure was gained and one of the fundamental theories of biology‚ the Cell Theory was developed.

Experiment 9/5 Voltaic cells AIM How the change the concentration of the electrolyte CuSo4 (solution of ions) affect the voltage of the electrochemical cell BACKGROUND An electrochemical cell is also called a voltaic cell‚ which derives electrical energy from redox reaction taking place within the cell. It consists of two different metals that are connected by a salt bridge. Eletrons always flow from anode to cathode‚ where anode is negative (reduction) and cathode is positive (oxidation)
