Forensic science is the application of science to both criminal and civil laws. Those who work in this field are called forensic scientists. Forensic scientists collect‚ preserve‚ and analyze scientific evidence during the course of an investigation. Some forensic scientists travel to collect physical evidence while others work in laboratories to analyze the evidence. There are ten different forensic units and departments that have different purposes and different roles. These units and departments

oxygen from the air into our blood‚ nourishing the trillions of cells that make up our bodies. The lungs also clean the blood of carbon dioxide waste created when cells use oxygen (Natural Geographic‚ 2012). In experiment one I hypothesize that the effect of respiration changes on carbon dioxide‚ concentration in exhaled air will be greatest the longer the respiration rate is increased. I predict that during normal breathing the time it takes to detect the carbon dioxide will be greatest.

that polytene chromosomes had formed just like my prediction. This result supports my hypothesis that endomitosis has occurred. I observed that polytene chromosomes were big‚ light and had dark banding patterns with all homologous pairs of chromosomes connected to chromocentre similar to Baudisch ’s observation in his 1977 paper. The disadvantage of the method used was that the extraction process was very hard and without lots of practise is a not practical method for fast good results. The biological

Photosynthesis and cellular respiration go hand in hand‚ but there are differences of the two that most people overlook. Without either of these processes though‚ the human species wouldn’t exist. Along with every other plant or animal. Photosynthesis starts off the cycle‚ with light energy being trapped within the cell and transported into the chloroplast. Water and carbon dioxide follow the similar route of the light energy and as so is collected into the chloroplast. Photosynthesis tends to take

Caring Science Integration Paper: Promoting and Accepting the Expression of Positive and Negative Feelings Hirschsprung disease‚ or Congenital Aganglionic Megacolon‚ is a congenital anomaly that comes from a physical obstruction due to the intestines not performing peristalsis. It accounts for ¼ of all cases of neonatal intestinal obstruction. The pathology of HD is because of the absence of ganglion cells in the affected areas of the intestine which results in a loss of rectosphincteric reflex

PHOTOSYNTHESIS (How do the light dependent and light independent reactions provide food for a plant?) Why? How important are plants to life on Earth? Could life as we know it continue if there were no plants? Read on the find out why plants are truly the cornerstone of life.

Misael Acosta Photosynthesis Lab Report Ms. Rocha AP Biology 4th Period II. Intro/Background 1. In order for oxygen to be present photosynthesis must occur. Photosynthesis takes in light and CO2‚ and through a series of steps produces oxygen. Photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. Examples include the production of O2 or the consumption of CO2. All the oxygen within the leaf disks will be removed before being placed

the Earth’s atmosphere before 1500 A.D. was between 200 and 300 ppm. The carbon dioxide content today is about 450 ppm. Which single historical development can be blamed for this increase? a) the invention of agriculture b) the Industrial Revolution c) the American Revolution d) splitting of the atom e) the election of George Bush Answer: b 7) Which of the following is a major effect of El Niño: a) heavy rains along the western coast of South America b) droughts in California c) increased

Photosynthesis vs. Solar Cells When the subject of solar energy is discussed both the ideas and processes of photosynthesis and solar cells are the basis of these conversations. While both are processing or converting light into energy‚ which will be explained further‚ it is the type of energy that is vastly different. Photosynthesis as a process used by certain plants to convert the suns energy into food. When the electromagnetic energy from the sun reaches a green plant the chlorophyll
