A. Billions B. Changing C. Fossil records

27
Q

In 1859, A. published On the origin of species by means of natural selection. The book accomplished two things.

  1. it presented evidence to support the idea of B. (species living today are descendants of ancestral species).
  2. Proposed a mechanism for evolution called C,
A

28
Q

Natural selection was inferred by connecting two observations. Individuals within a population A. Different characteristics and B. from other individuals. A particular population of individuals produces more C. than will survive to produce D. of their own. Darwin inferred that those individuals with heritable traits best suited to the environment are more likely to E. and F. than less well-suited individuals.

A

A. Inherit B. Vary C. Offspring D. Offspring E. Survive F. Reproduce

29
Q

Natural selection is an A. Results from exposure of heritable variations to environmental factors that favor some individuals over others. Over time this results in B. of new species adapted to particular environments.

A

A. Editing mechanism B. Evolution

A

A. Evolution

31
Q

A. is a way of knowing an approach to understanding the natural world. A process of inquiry. Search for information, explanations and answers to questions. B. involves making observations, forming hypotheses and testing predictions. C. often stimulate us to seek natural causes and explanations.

A

32
Q

A A. is a proposed explanation for a set of observations. A B. is supported by a large and usually growing body of evidence and explain a great diversity of observations

A

A. Hypotheses B. Theory

A

A. Hypotheses B. Reasoning

34
Q

Using reasoning we realize that the problem is either the 1 bulb or 2 batteries. The hypotheses must be A. (some way to check the validity. The hypotheses must be B. (some way to show it is not true).

A

A Testable B. Falsifiable

35
Q

Another Hypotheses A. helps protect nonpoisonous king snakes from predators where poisonous coral snakes also live.
