ANATOMICAL EVIDENCE OF EVOLUTION In our studies of the anatomy and development of animals we have discovered that many living creatures that look quite different on the surface have similarities underneath their skin that suggest that they are related to each other. This is evidence that living creatures have evolved. (d) Determine how biochemical similarities can be used by scientists to provide evidence of evolution Procedure: Part A. Numbers of Amino Acids Figure 1 represents the amino acid sequence of corresponding portions of the hemoglobin molecules. The study of fossils as well as work in embryology, biochemistry and comparative anatomy provides evidence for evolution. In this lab you will learn about homologous, analogous and vestigial structures and their significance in evolution theory. You will also compare amino acids sequencing of humans to other vertebrates. Unit 5 stuty nguide evolution guide Kindle online on 05.prizcats.site.

Answers: 3

A - True

Explanation:

Summary. Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).

A- True
Please let me know if this is correct

Option (C)

Explanation: According to the law of Uniformitarianism, the geological processes that has been taking place now must have taken place in the past, and will also take place in future, at a constant speed, in long term.

Darwin suggested that the same Uniformitarianism process takes place in case of living beings also. According to him, these living creatures undergoes evolution and in this process, gradual changes in the organisms occurs being a long-term continuous process.

Thus the correct answer is option (C).

Option C

Explanation:

Uniformitarianism, states that the geological processes that take place today would have taken place in the past and it will continue in future as well.

Darwin suggested that the the evolution takes place over a period of time. It takes time to change and this change takes time.

Both the laws states the same thing, that the geological processes and the process of evolution takes place over a period of time and does not takes place rapidly.

Analogous structures are those that have a similar function but whose origin is different. Homologous structures have the same function and also start from the same origin.

Explanation:

Biochemical evidence for evolution lab 12 answers questions

Convergence is the evolutionary phenomenon by which different organisms that are evolutionarily distant tend, under equivalent environmental pressures, to develop analogous characteristics.

Analogous structures are those that have a different evolutionary origin, but fulfil very similar functions. For example, the wings of a bird, the wings of a bat and the wings of an insect all are for the same thing (flight) but their phylogenetic origin is not the same. This means, they fulfill similar functions by similar means, without having the same evolutionary origin.

The development of homologous structures occurs through divergent evolution, where two related species change a common ancestral structure during their evolution in order to survive by performing different functions.

Then, if they have the same evolutionary origin, they are homologous. So, if two structures have the same function by similar means and also start from the same origin, they are homologous structures. For example, the extremities of vertebrates, similar skeletal structure, but for different uses.

A. Artificial Selection

Explanation:

He is artificially breeding the best of the cows to create more milk.

I hope I helped :) :) :)

Homologous structures can be described as the structures which are similar to one another present in different organisms. These similarities depict that the organisms might have a common ancestor i the past. For example, the forelimb of man, birds, dogs.

Analogous structures can be described as structures in different organisms which perform the same function but might not have a common origin. For example, the wings of bats and birds.

In the field of comparative anatomy, homologous structures can be described as structures which are present in different organisms which are similar and show that the organisms had a common ancestor in the past. On the other hand, analogous structures can be described as structures which are similar in function but might not possess a common origin.

Example of the homologous structure is the forelimb of dogs, humans and birds. All these structures might not perform the same function but are structurally similar.

Example of analogous structure includes the wings of a bat and bird. Although similar in function, they do not show a common origin.

The answer is B. artificial selection. Artificial selection is . a process in the breeding of animals and in the cultivation of plants by which the breeder chooses to perpetuate only forms that have certain desirable inheritable characteristics (such as, in this case, cows that produce the most milk).

True. Homologous structures provide evidence of a common ancestor.
