Kinetic Energy: Consider a baseball flying through the air. The ball is said to have "kinetic energy" by virtue of the fact that its in motion relative to the ground. You can see that it is has energy because it can do "work" on an object on the ground if it collides with it (either by pushing on it and/or damaging it during the collision). The formula for Kinetic energy‚ and for some of the other forms of energy described in this section will‚ is given in a later section of this primer. Potential

Cell membranes are a bilayer make up of phospholipids‚ proteins‚ and cholesterol. Its main function is to regulate what comes in and out of the cell by means of diffusion‚ transport proteins and protein channels. Trans membrane proteins transport polar solutes across hydrophobic regions of the bilayer. Diffusion occurs when solutes are transferred from a high concentration of that solute to a lower concentration of solutes. Solutes do not depend on the concentration of other solutes‚ which allows

microscope is that it has a greater magnification‚ so you can see more detail about the organism. It would be preferable to use a light microscope when you want to see the cell in the act of moving or dividing. 2. Prokaryotic cells don’t have organelles like eukaryotic cells do. Eukaryotic cells contain its DNA within its nucleus‚ while prokaryotic cells keep it within the nucleoid. Prokaryotic cells are also more minute than the eukaryotic cells. Also although they both contain ribosomes‚ they are composed

RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and oxygen that

When it comes to energy there are so many different options. Do you go for renewable energy and plan for the future? Or do you go for nonrenewable and do what is best right now. I believe that the city of Houston should use nuclear energy to provide energy to the fourth largest city in America. Nuclear energy is the most efficient and reliable source of large-scale‚ around-the-clock source of power. Nuclear power plants maintain a national average reliability between 85 and 90 percent. Many power

Benefits of Moringa Through Zija Products Getting the Benefits of Moringa can be as simple as sprinkling moringa oleifera powder from Zija over your morning glass of juice. Alternatively‚ you could start your morning off right with a delicious and highly nutritious moringa drink from Zija. If you are in a hurry‚ there is even a capsule form of moringa oleifera that you can take just before you enjoy your first meal of the day.

Staphylococcus aureus‚ and Escherichia coli was identified and one result was inconclusive. The focus of this paper will be on the description of the just one of the three bacteria and some of its effects on humans. The first test done was a differential stain (gram stain) to determine the unknown microorganism cell shape and arrangement. The gram staining is done by first putting a sample of the unknown bacteria on a slide and it was heat fixed taking care not to over or under fixed the slide. The

Procedure outlined below is slightly different. 1. Remove a green leaf fom a plant that has been exposed to sunlight for a few hours 2. Half-fill a 250cm3 beaker with water. Heat the water until it boils. Keep the water at boiling point. 3. Use the forceps to place the leaf in the boiling water. Boil for 2 minutes. 4. Turn off the Bunsen Burner. (If you are using a heat source without a naked flame - electric water bath or hot plate - this step is uneccesary.) 5. Place the boiled leaf

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.

The rate of photosynthesis in each of the beakers will depend what is wrapped around the beakers such as red and blue cellophane‚ as well as the control of the experiment the beaker without cellophane. The cellophane will directly impact the light getting absorbed as well as the amount of CO2 in the beakers. Which overall as result will determine the final color of the water mixed with bromothymol blue. What was being measured was the color of the water after CO2 has been blown in the beakers. The
