The Galapagos Islands, a small group of islands off the coast of Ecuador, is home to reptiles such as the giant tortoise and the iguana. The eastern islands are much older than the islands to the west. Which statement about the origin of these reptiles is best supported by this information?

The common ancestors of the reptiles probably came from Equador.

The ancestor of each species came from different continents at different times.

The common ancestor of each species evolved in Peru and came to the islands at the same time.

The picture shows the members of the Camelidae family. The physical features and the geographical origin of these animals provide evidence that -

they live in the same type of environment.

have slowly evolved to become herbivores.

What conclusions can be made based on this table shown?

the red panda and the racoon are the most closely related

the American black bear and the giant panda are most closely related

the giant panda and the red panda are most closely related

Guppies are small fish that live in freshwater. Most guppy species reproduce sexually, but some reproduce asexually. There are two lakes in a particular region. One lake contains a species of guppy that reproduces asexually. The other lake contains a species of guppy that reproduces sexually. A scientist studying these lakes predicts that the sexually reproducing guppies would survive better that the asexually reproducing guppies if a fungus was introduced in both lakes. Which statement supports this hypothesis?

The sexually reproducing guppies have a variation of inherited characteristics.

The sexually reproducing guppies are identical to one another.

The sexually reproducing guppies require only one individual for reproduction.

The sexually reproducing guppies are carriers of recessive genes.

A gene from organism A can be put into organism B and work because

all organisms share the genetic code

they have the exact same genome

In what way is the DNA of a nerve cell different from the DNA of a muscle cell?

The DNA is the same but different genes are turned on and turned off in each cell

The DNA is the same but each cell contains different genes

The DNA is different, but the same genes are turned on and off in each cell

The DNA is different, but each cell contains the same genes

Which of these is responsible for the different morphologies of these cells?

None of these account for the different morphologies

In turtles, the temperature of eggs during a certain period in their development is the deciding factor in determining the gender of the offspring. In the case of the European pond turtle, an incubation temperature of 23 degrees celcius results in all male baby turtles, while an incubation temperature of 30 degrees celcius results in all female baby turtles. What is a likely reason for such gender development in turtles?

a change in temperature causes a change in the expression of the genes determining sex

a change in temperature results in the mutation of a gene in the developing embryo

a change in temperature causes a variation during cell division of the developing embryo

a change in temperature reverses the expression of the dominant and recessive alleles

What is the importance of a standardized taxonomic system to the scientific community?

To have a universal scientific naming system

To have many different common names for one species.

To organize species' cells, tissues, organs, and organ systems

To analyze species genetic information

Which is the best prediction regarding the current classification system?

The system may change as new information and organisms are discovered.

Scientists will become bored with the current system and develop a new one.

Over time, organisms will become extinct, so classification will become simpler.

The system is set in stone and most likely will not change.
