White eyes in flies are typically caused by some combination of four distinct mutations. research each of these mutations (below) and summarize the genes they occur in by listing each one's: • normal function • what happens to a fly's phenotype when it is homozygous for a knock-out/null mutation (and why) • what chromosome it is found on • if the typical mutation is dominant or recessive

Been sitting here trying to take this test and don't know this answer! place the events of a feedback mechanism associated with body temperature in the correct order. ·nerve cells send message from skin to the brain ·body returned to normal temperature around 98.6 degrees f ·temperatures regulation center in the brain sends out signals ·body temperature exceeds 98.6 degrees f ·sweat glands throughout the body activate to cool off skin surface it is a 1 through 5 question in biology!
