Answer:
4 beats
Explanation:
<u>The number of beats of the heart that will take blood from Aorta to The Brain </u>
n = Distance from Aorta to brain / distance per beat
<em>Given that distance per beat = 7.5 cm ( calculated value outside scope of question using the data attached below) </em>
n = 30 cm / 7.5 cm
= 4 beats
Answer :3. similarities among vertebrate forelimbs suggest that they evolved from a common ancestor.
Explanation:
The study of differences and similarities in the anatomy of different species is comparative anatomy. It is based on the concept that
1.)Homologous structures which are present in different species, because they have a common decent and must have evolved divergently from a shared ancestor. Theses anatomic structures may not be used for the same purposes. For example the forelimb of fox and whale.
2. Some structures (Analogous)which are similar in different organisms must have evolved ,(acquired through natural selection) through convergent evolution in similar environment, and not inherited from a recent ancestor. These organisms usually use these structures for a common purpose. For example the streamline body shape of shark and porpoises, which though are used for a common purpose of swimming, were inherited from different ancestors.
. Example of comparative anatomy is the common bone structures in forelimbs of fox, whales, bats, and humans. These appendages is made up of the same basic parts; despite serving different functions.
Comparative anatomy helps scientists in classification of organisms based on their similar characteristics of their anatomical structures.
Answer:
Heat decrease the thermal energy of an object as energy moves to the air. Heat causes the thermal energy of the object to increase as energy moves from warmer air to the colder object
