Read the statements below and place them in order of how they would occur in order for a trait to be favored (selected for), and therefore increase, within a population.
Change to make multi choice?
The overall number of organisms that have the adaptation increases within the population.
The organisms that survive, reproduce and pass on their genes to their offspring (babies).
Some of the organisms within the population have traits that help them to survive better, and some of the population do not have these traits.
The environment that the organisms live in changes.
The organisms with traits fit for the environment survive, and the organisms that are unfit die off.
READ THIS IN ORDER TO ANSWER QUESTIONS 2 & 3:
The picture (below) shows what the environment was like both before and after the Industrial Revolution. Industrialization in England produced black soot (powder) that covered many tree trunks and branches. At about the same time, the number of light-colored moths in this part of the country began to decrease over time.
Why did this change within the moth population occur over time?
Over time, Natural Selection caused a change in the moth population metioned in the question above. Which of the following most likely occurred as the result of Natural Selection?
*
Adaptations that result from Natural Selection are expected to increase the fitness of an organism. In terms of Natural Selection, which of the following best describes fitness?
*
The green frog (Lithobates clamitans clamitans) is found in many parts of the United States. The table below contains some information about this frog.
Why does the ability to lay 1,000 to 5,000 eggs increase the fitness of the species of L. clamitans clamitans?
*
The table (below) shows the survival rate of two types of beetles in the same environment over a period of three years.
Which statement about the beetles in this environment is best supported by the data?
*
The aye-aye lemur is a mammal that feeds mostly on insect larvae that live inside trees. The aye-aye lemur has a specialized middle finger that is long and thin. The aye-aye lemur moves along a tree branch and taps the branch with its specialized finger. When the aye-aye lemur hears a difference in echo, it will tear open the bark with its teeth until the insect tunnel is exposed (visible). The aye-aye lemur then uses its specialized finger to reach the insect larvae and remove it.
Which selective pressure most likely resulted in the development of the aye-aye lemur's special adaptation?
*
A new predator of rabbits has been introduced within an ecosystem. This new predator runs faster than the native predators of rabbits.
Which statement describes what will most likely occur in the rabbit population due to the introduction of the new predator?
*
The quiver tree grows in desert areas in southern Africa. In recent decades, average temperatures have been rising in southern Africa. Scientists predict that this warming trend will continue. Quiver trees in the hottest parts of their range near the equator are dying, but quiver trees at high elevations, or in parts of the range that are farther from the equator where it is cooler are growing and reproducing.
Which of these best explains what is happening to the quiver tree population in southern Africa?
*
Male guppies (fish) found in areas without predators are more colorful than the ones found in locations with large predator populations. This is due to the fact that being colorful increases the chances of finding a mate (female), but it also increases the chances of being seen and eaten by a predator. A population of adult guppies (fish) coming from an area with a large number of predators is moved to a nearby area with only a few predators.
Which of these is most likely to happen over a few generations?
*
Doctors prescribe antibiotics to people when they are sick with bacterial infections. Some individual bacteia have genetic mutation that makes them resistant (unaffected/does not hurt them) to the antibiotics .
Which statement best describes how only a few resistant bacteria can result in the antibiotics becoming ineffective (stopped it from working) in a person?
*
Which result is most likely to occur to the beetle population due to natural selection?
*
Common baboons lives on the savanna in breeding groups called troops. While females tend to stay with the troop, younger or less dominant males may leave to join a neighboring troop.
Which of these is likely outcome of movement by young males?
*
Conservation biologist studying cheetah population have determined that the lack of genetic diversity among the cheetah is due to genetic drift.
Which statement explains the most likely consequences of having a low genetic diversity on the cheetah population?

After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors. For example, Jaekelopterus rhenaniae, a giant scorpion species that lived 255 million to 460 million years ago, was 2.5 meters (over 8 feet) long!
Which of the following conclusions is supported by this information?
*
In 2010, scientists excavated (to dig with a shovel) a skull fossil that provides evidence of a newly discovered species of big cat. Based on the evidence, scientists hypothesized that big cats branched off from smaller wild cats about 6 million years ago.
Which of these resources did the scientists most likely rely on to form their hypothesis?*
*
Bactrian camals, dromedaries, llamas, and alpacas are all members of the same taxonomic family, Camelidae. Members of this family all have two toes, no hooves, true canine teeth, and a split upper lip. The family Camelidae originated in North America.
The physical features of animals in this family and the family's geographical origin provide evidence that all of these animals...

An analysis of DNA and RNA sequences can be used to classify organisms. A dendrogram, such as the one shown below, is based on moleculer data. It can be used to represent evolutionary relationships within a group of organisms that are hypothesized to have descended (come) from a common ancestor.
Which statement is best supported by the information in this dendrogram?
