The remnant of an organ that had a function in an early ancestor is known as a(n) ____

This occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene

What is the branch of biology that studies the molecular basis of biological activity?

Changes in DNA are called ____

Scientists believe that all life on earth developed from simpler organisms three billion years ago. This is known as _______

The organisms that survive in this world of competition are the ones that are

Which one of the following is least likely to cause a species to become extinct?

Evolution is ____

What do you call a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor?

What do you call a scientist who study fossils and uses a variety of techniques to reveal what an ancient organism looked like, where it lived, what it ate, and how it behaved?

This law states that older fossils and rocks are found in lower strata than younger fossils and rock layers.

What is the difference between analogous and homologous structures?

Which of the following is an example of an abiotic factor?

Fossil evidence shows that structures considered vestigial in living organisms ______

In natural selection, the species which survive are ____

What is an attribute of the organism that enables the organism to survive and reproduce in its habitat called?

In which region do succulents grow?

 A frog combining glucose with urine to make antifreeze in its bloodstream so that it can survive the winter.

White coat of polar bears helps them to

Plants growing in drier conditions tend to have small numbers of stomata on their lower leaf surface to save

What name is given to a feature of an organism that improves its chances of survival?

When is an organism no longer well adapted?

Over many generations, what would the number of well-adapted organisms in a population be expected to do?

What is a physiological adaptation?

The white fur of a polar bear is an example of which form of adaptation?

Which of the following is an example of a behavioral adaptation?

The ability of a seal to divert more blood to its brain during diving is an example of which form of adaptation?

In a small group of people living in a remote area, there is a high incidence of “blue skin”, a condition that results

from a variation on the structure of hemoglobin. All of the “blue-skinned” residents can trace their ancestry to one

couple, who were among the original settlers of this region. The unusually high frequency of “blue skin” in the area

is an example of

What is the difference between paleontologist and paleontology?

An organism’s genes affect what body structures, processes, and behaviors it has. An organism’s environment determines whether these features will help it to survive and/or reproduce.

A feature of an organism that improves its chances of survival is called an adaptation.

Over many generations, the number of well-adapted organisms in a population would be expected to increase.

A sample is a group of individuals of the same species that occupy a specific area over a certain period

The greater the biodiversity, the less stable an ecosystem becomes allowing for a unstable carrying capacity

Behavioral adaptations are changes in behavior that certain organisms or species use to survive in a new environment

Structural adaptation is an internal body process to regulate and maintain homeostasis for an organism to survive in the environment in which it exists

These are structures that are similar in related organisms because they were inherited from a common ancestor.
