A student is conducting an experiment to determine how cold temperatures affect the growth
instrument would give the most accurate measurement of water temperature?
a calibrated bulb thermometer that has a readout from -15°C to 25°C
a calibrated digital thermometer that has a readout from 50°C to 250°C
an uncalibrated bulb thermometer that has a readout from 0°C to 100°C
an uncalibrated digital thermometer that has a readout from -10°C to 100°C

the awnser is d i think

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

answer; i believe the answer is (polygenic inheritance;
