2) Two genes, w and m, control eye color and wing size, respectively in a species of fly. W_ individuals have red, wild-type eye color and M_ individuals have wild-type full size wings. Individuals that are ww are white-eyed, and individuals that are mm have miniature wings. A white-eyed, miniature-winged individual is crossed with an individual that is wild-type for both traits. The progeny types and counts are given below: red, full = 891 red, mini = 425 white, full = 432 white, mini = 850 a) What are the parental genotypes? (3 pts) b) What is your estimate for the recombination frequency for these genes? (3 pts)

Objectives Using a ventilation fan and temperature sensor to regulate the temperature of a room. A room's temperature can be monitored and a DC motor fan can be controlled using an Arduino controller. The sensor input can be used to modulate the RPM of the motor. Motor RPM should increase as temperature increases. As a suggestion you can use TMP36 temperature sensor and a brushed DC motor with a suitable driver. Instructions In this project, you will use the Arduino development environment to program an Arduino UNO microcontroller. You will wire and program the Arduino (on TinkerCAD) to take temperature sensor input of the room. The produced data (temperature) must be displayed on an LCD screen along with the DC motor status (on/off) and speed.

A meteorologist studied the maximum temperatures at various latitudes for January of a certain year. The results of the study are shown in the following table. Latitude (in $^\circ$N), x 23 28 35 44 55 43 46 Maximum Temperature (in $^\circ$F), y 79 67 46 55 20 45 53 (a) Use the points (23, 79) and (55, 20) to find a linear model that will predict the maximum temperature y (in $^\circ$F) at a latitude of x degrees north of the equator. y = (b) Use your linear model to estimate the expected maximum temperature in January at a latitude of 45$^\circ$N. Round to the nearest degree. $^\circ$F
