Tail length in mice varies within a population. Scientists observed change in the distribution of an enguss
in a mouse population over time. At the genetic level, what has most likely happened to the allele for the
shortest tail lengths?

The allele changed from being dominant to being recessive.

The allele changed from being autosomal to being sex-linked.

The allele became less frequent than the alleles for longer tail lengths.

The allele began to code for long tail lengths instead of the shortest ones.

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 8 options: the cold balloon expands and rises. the warm balloon shrinks and sinks. the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the warm balloon expands and rises. the cold balloon shrinks and sinks.
