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

large enough‚ it could be washed‚ filtered‚ and weighed. The percentage of chloride present was found to be 24.73695223 (±0.00000006) %. Introduction The purpose of this lab was to determine the percentage of chloride in an unknown soluble salt sample through a gravimetric method known as precipitation gravimetry. The objective was to accurately and precisely convert the unknown sample containing the chloride analyte to another known solid‚ silver chloride. Once the mass

emulsified grease or oil amount in the water samples by utilizing from the partition-gravimetric method. Introduction: Oil and grease is an important parameter for water quality and safety. Regulatory bodies worldwide set limits in order to control the amount oil and grease entering thewater reservoirs or the sea through industrial discharges and also limit the amount present in drinking water. The partition – gravimetric method involves extraction of dissolved or emulsified oiland grease from water

Bacterial Morphology MLT1 Task 11- Lab 2 Johnny Archuleta Western Governors University Question A and C answers. A wet mount stain is when a drop of water is placed onto the microscope slide. The water on the slide helps to support the organism and sample. The water fills the space between the cover slip and the slide. This action allows the light from the microscope to pass through the slide and the sample for better visualization of the organisms. A direct stain occurs when a charged

Be familiar with using a titrator. To tell wether your water is hard or soft. Hard water however does not create a threat‚ but is bad for your pipes causing them to crust. To measure water’s “softness” you are truly measuring the amount of CaCO3 in the water. Procedure: Assemble
