Answer:
Natural selection in an aquatic environment resulted in significant changes to whale forelimb anatomy.
Explanation:
Genetic data reveals that the species of humans, bats and whales have evolved from the different organisms which a common ancestor at early time. The evolution of upper forelimbs of the humans and the bats have similar skeletal structure but those oh whales forelimbs skeletal structure has different shapes and proportions.
It is merely because of the adaptation and evolution over time of the whale species who lives in the waters resulted in the adaptation to the aquatic environment and modification of the forelimb skeletal structure.
Thus the answer is ---
Natural selection in an aquatic environment resulted in significant changes to whale forelimb anatomy.
Answer:
D - Legal Documents
Explanation:
Rich medium communication requires feedback (verbal or nonverbal) and legal documents are static - once they are written, there is no more feedback. All of the other options give an opportunity to interact with others.

Answer:
prosocial behavior of the social learning theory.
Explanation:
Social learning theory: In psychology, the "social learning theory" was introduced by Albert Bandura, and is described as a theory of social behavior and learning process that states an organism (animal, human beings) learns new behavior by imitating and observing others. It represents the fact that an organism does what it sees.
Behavior is being learned via observation of environmental cues. It involves mainly four distinct steps i.e, motivation, attention, reproduction, and retention.
In the question above, the given statement example of prosocial behavior of the social learning theory.
While professional singers can command a pitch range of two octaves or more, an untrained voice is usually limited to about "An octave and a half".
<u>Answer:</u> Option C
<u>Explanation:</u>
A musical interval between two notes or between one musical pitch and another with double its frequency, is called an octave. Like A3 to A4 is the interval of one octave. It is a natural mechanism popular as the "basic miracle of music" its application is well spread in most of the musical systems. The pitch in one or more than one octave can be calculated as follows:
For an instance, if one note has a frequency of 440 Hz
- One octave above has a pitch: 2 × 440 Hz = 880 Hz (A5).
- The frequency of two octaves above is: 2 x 880 Hz = 1760 Hz (A6).
- The note one octave below is at 220 Hz
- The ratio of frequencies of two notes an octave apart is hence 2:1.
