Are you a "Supertaster?!" Materials Included: Premium Storage Case 100 Strips containing Phenylthiourea (PTC) 100 Strips containing Sodium Benzoate 100 Strips containing Thiourea 100 Strips containing NO chemical (Control) Key Vocabulary: Genotype: the specific genes found in DNA. Phenotype: the physical expression of genes (examples: eye color; tasting ability). Heredity: the passing of genetic information from parent to offspring. Punnett Square: a method for determining the qualitative chances of offspring inheriting certain genes from their parents. Just as humans have different levels of acuity in the senses of smell and sight, they also have differences in their ability to taste. Approximately 25% of Americans are considered "supertasters" and, of this subset, people have varying levels of "supertasting" ability. "Supertasters" are people who have the ability to taste the substance Phenylthiourea (PTC). Some people cannot taste this substance at all and others taste it quite distinctly. Whether or not a person is a supertaster (phenotype) is dependent on his/her genetics (genotype). For the purposes of this experiment, the dominant supertasting gene will be represented as "S" and the recessive supertasting gene will be represented as "s." Based on the genetics involved, there are four basic types of tasters à normal tasters (no S or s), standard supertasters (__ s), recessive supertasters (ss), and dominant supertasters (S__).

Manufacturer: Supco Brand: Supco Model: EM60 Color: Multicolored

The Supco EM60 dual-input digital differential thermometer with probes is for use in applications requiring a broad range of temperature measurements including superheat measurements, food service applications, and heating, ventilation, and air-conditioning system maintenance. When using a K-type thermocouple, it measures temperature from -200 to 1300 degrees C (-328 to 2372 degrees F). When using a J-type thermocouple, it measures temperature from -200 to 1200 degrees C (-328 to 2192 degrees F). It has a best accuracy of + or - 0.1% of reading + 0.7 degree C (1.4 degrees F). The thermometer accepts K-type thermocouple probes, which have a broader temperature measurement range than a thermistor sensor but provide lower accuracy, or J-type probes, which provide higher accuracy but have a narrower temperature measurement range than a K-type probe. This dual-channel thermometer has two inputs for connecting temperature probes (two probes are included), allowing the operator to measure the temperature of two samples at one time. The LCD screen can display the current temperature measurement for either input channel as well as the difference between the two channels. It can also display the highest or lowest temperature reading for a session. The operator can choose to display readings in degrees Fahrenheit or Celsius. The thermometer's internal memory can record up to five sets of minimum, maximum, and differential temperature data for future recall. The hold function keeps a measurement on the display so it can be recorded. The operator can set high and low temperature alarms to sound when measurements exceed or drop below the preset limits. The thermometer operates on three AAA batteries (included), and the thermometer will automatically turn off after 20 minutes of non-use to conserve battery life. A low-battery indicator alerts the operator when the batteries need to be replaced. Two K-type wire probes are included with the thermometer. A lanyard is included to help protect against accidental drops, and a sensor ...
