their own 3. Produce energy 4. Contain Ribosomes 5. Have enzymes Double membranes 1. Passive Transport- Diffusion‚ from high to low concentration‚ small non-polar particles fit between phospholipids 2. Facilitated Transport (a.k.a facilitated diffusion)- Diffusion‚ uses a channel protein‚ large or charged particles a. Ex: Fructose‚ amino acids 3. Active Transport- Pushing particles from low to high concentration (against the gradient)‚ uses a carrier protein 4. Vesicle Formation or Membrane

KOMODO BIO FUELS – CASE STUDY There is several risk identification to be asked in this projects‚ those are as follows: 1. Environmental risk * This is particularly in connection with natural resources‚ there is a risk that the natural resources‚ raw materials‚ or other factors of productions necessary for successful operation may become depleted or unavailable during the life of project * Does the company engage the independent consultant to do the assessment and research of conservation

incomplete breakdown of food. Happens when there is not enough oxygen. Equation‚ Glucose & O2 (not enough) to form CO2 Lactic Acid or Alcohol (depending on the organism) & a little ENERGY. 3. Sensitivity It is the ability to detect and respond to a stimulus. 4. Growth It is the permanent increase in size and quantity of cells using materials absorbed from the environment. 5. Reproduction It is forming new individuals of the same species either sexual (2 parents) or asexual (1 parent) \ 6. Excretion It is removal

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Turn on the lamp and allow the plant to equilibrium for 5 minutes. 4. Suck up the solution from the boiling tube. Close the clip completely Record the starting position of the meniscus in the pipette. 5. After 5 minutes‚ record the final position of the meniscus in the pipette. Calculate the rate of photosynthesis. Record
