taking in materials for growth, energy and development

Question 8

what is classification important in?

Answer 8

1. conservation
2. understanding evolutionary relationships

Question 9

how can you tell how closely similar are organisms with features?

Answer 9

the more features organisms share the more recently they have separated from one another during evolution

Question 10

what is a species?

Answer 10

groups of organisms that can reproduce with each other to produce fertile offspring

Question 11

what is the binomial naming system?

Answer 11

the scientific naming system of organisms

Question 12

what does the protein structure of organisms show about the relation with species?

Answer 12

organisms which are very closely related have similar acid sequences in proteins

Question 13

what does the DNA of organisms show about the relation with species?

Answer 13

closely related organisms have very similar base sequences in DNA because there is less evolutionary time for mutation
