Abstract For this lab the rate of photosynthesis was analyzed upon plant leaves. A sample of a light exposed and a not-light exposed leave were used to clearly identify the role of sunlight in the process of producing and storing energy. Aim We are trying to find proof‚ to demonstrate the necessity of light and chlorophyll in the process of photosynthesis. Background Photosynthesis occurs in organisms which contain chlorophyll. It’s a process that involves the chloroplasts to synthesize glucose

Lab 11: Animal Behavior Introduction Ethology is the study of animal behavior. There are two specific categories of behavior: learned ad innate. Orientation behaviors place the animal in their specific environment. Animals move away from sensory input in taxis where as behavior is the response to sensory input. Stimulus’ of light‚ heat‚ moisture‚ sound‚ or chemicals are mostly found in taxis. Kinesis is the movement that does not result in orientation with stimulus. When animals respond to each

Enzymes in Living Tissues Purpose: The purpose of the lab was to analyze the enzymes in living tissues‚ represented by the pieces of liver. Also‚ hydrogen peroxide was used to demonstrate these effects. Storyboard: Materials: 2 50 mL beakers 10 mL graduated cylinder 3% hydrogen peroxide solution Hot water bath Lemon juice or HCl Fresh liver Forceps Procedure: Measure 10 mL of hydrogen peroxide and record its temperature. Pick the liver up with the forceps and

Immobilized Enzyme Immobilized Enzyme * Enzymes which are attached to small bead made of alginate are called immobilized enzyme * However‚ whatever the nature of an immobilized enzyme‚ it must comprise two essential functions‚ namely the non-catalytic functions (NCF) that are designed to aid separation and the catalytic functions (CF) that are designed to convert the target compounds within the time and space desired * Immobilized enzymes might meet the increasing demand by manufacturers

The carrying capacity of a biological species in an environment is the population size of the species that the environment can sustain indefinitely‚ given the food‚ habitat‚ water and other necessities available in the environment. In population biology‚ carrying capacity is defined as the environment’s maximal load‚ which is different from the concept of population equilibrium. Population size decreases above carrying capacity due to a range of factors depending on the species concerned‚ but can
