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.
the correct answer would be b. lower permeability
Answer:
<u>Depending upon the mass of various bodies and the gap between them, such as planets, satellites, etc., there appears a pulling effect between these massive masses. This pulling effect is known as gravitational force. One can establish the relationship of the orbital period by equating the gravitational force with centripetal force and substituting the velocity relation with the period.</u>

<h3>I hope this helps!</h3>
I’m almost 100% sure it’s D, because environmental factors can induce a mutation. A mutation can be beneficial but it can also be harmful, so it’s neither B or C, and it can’t be A, because mutations can come from natural selection as well. So it’s D.
Limestone contains calcium carbonate which comes from animals that have shells, it already has carbon. Other sources are ocean animals which create shells that combine both carbon and calcium. Their dead bodies also release carbon to the ocean. Limestone is also known as a sedimentary rock that has carbon. Outside the ocean, limestone emits the carbon and becomes part of the carbon cycle. In addition to this, limestones are widely used by people becomes a part of the carbon cycle. Its component is present on asphalt, animal feed.
