Question

question 1 (1 point)the direct maipulation( by humans) of how a dog breeds in order to alter traits is called ____________a natural selectionb genetic driftc artificial selectiond survival of the fittestquestion 2 (1 point)what are examples of homologous structures?a whale fin and human handb butterfly wing and bird wingc stem of rose and trunk of treed leaves on a tree and fruit of a treequestion 3 (1 point)what type of cellular evidence do we have for evolution?a all living things breathe carbon dioxideb all living things breathe oxygenc all living things are made of the same basic building blocksd all living things have the same dna

Explanation:

Question 1:

Artificial selection is the human-controlled breeding of organisms to select for desired traits, which matches the description of human manipulation of dog breeding to alter traits. Natural selection, genetic drift, and survival of the fittest are natural evolutionary processes not driven by human intervention.

Question 2:

Homologous structures are body parts from different organisms that share a common evolutionary origin (similar underlying structure, even if different functions). A whale fin and human hand have the same basic bone structure, inherited from a common ancestor. Butterfly and bird wings are analogous (similar function, different origin), while the other options are not homologous structures.

Question 3:

All living organisms are composed of the same basic cellular building blocks (like nucleic acids, proteins, lipids, and carbohydrates), which is cellular evidence for a common evolutionary ancestor. Not all organisms breathe carbon dioxide or oxygen, and not all have identical DNA.

Answer:

Question 1: c. artificial selection
Question 2: a. whale fin and human hand
Question 3: c. all living things are made of the same basic building blocks
