Answer:
Carroll has spent his career studying how evolution occurs at the genetic level, pinpointing many of the molecular changes that lead to new traits and new species. Most of Carroll's discoveries have come to light by studying the common fruit fly Drosophila melanogaster, the workhorse of modern molecular genetics.
Have a great day!

Answer:
Speed of the hawk, v = 40.4 m/s
Explanation:
It is given that,
Exact frequency of the female, f = 785 Hz
Observed frequency of female, f' = 890 Hz
Speed of sound, v = 343 m/s
Let v' is the speed of the hawk. It is based on the concept of Doppler's effect. We know that when the object approaches you, its speed is given by :
v' = 40.4 m/s
So, the speed of the hawk is 40.4 m/s. Hence, this is the required solution.
Answer:
The answer is 14.8 m/s.
Explanation:
Substituting 22.1 revolutions for f, 6.4 meters for R in Relation between velocity and frequency of motion.
V = (2π) ( 22.1) (6.4)
= ( 2π) ( 22.1 rev/ min) ( 1min÷ 60 s )(6.4)
= 14.8 m/s.
