alicia conducted an experiment to find out which insulating material holds in the most heat. she did multiple trials of each test and recorded observations of each trial.

why did alicia most likely do more than one trial? check all that apply.
to increase the reliability of her data
to provide a better understanding of the concepts she investigated
to prevent other people from using the data incorrectly
to in arriving at a conclusion even with inaccurate data
to reduce the likelihood of errors in the experiment

They both have rock surfaces

The answer is c i just finished taking the test

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. 

  like australopithecus afarensis; probably the direct ancestor of this group. africa: 5.8 to 4.4 million years ago.
