The chart below shows three different stages of embryonic development for three different animal species. Stages of Development of Three Animal Species
species 1
species 2
species 3
The earliest stage in the chart appears very similar for all three species. For example, all three embryos at
this stage have gill slits and a large embryonic tail.
What do these similarities most likely indicate?
A. All three species evolved in the past 100 years.
B.
All three species look very similar as adults.
C.
All three species share a distant common ancestor.
D.
All three species evolved from a single mammalian ancestor.

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.
