Read the scenario and answer the following questions: a. how could the scenario have been prevented? b. how should the student respond in the scenario to minimize the harm? during an experiment, carin carefully pours solution a from a test tube into a beaker. krystal sneaks up behind carin to wish her a happy birthday. carin accidentally drops the beaker on the floor, shattering it on her uncovered toes.

The scenario could be prevented by two main ways:
1) Krystal should be more responsible in the lab
2) Carin should wear lab appropriate attire, including closed shoes

To deal with this scenario:
1) Cain should wash her feet in the closest washing station without walking too much to prevent cuts from the glass
2) After rinsing the chemical and glass off, she should get medical attention to ensure no remaining glass or chemicals are on her skin.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
