1. the graph shows data reported by the international union for conservation of nature (iucn) about species that have become extinct or are at risk of extinction, and vertebrate extinction rates from 1500 to 1900. what does the graph?
a. the extinction rate of all vertebrates has been constant over time.
b. the extinction rate of all vertebrates has increased over time.
c. the expected extinction rate is greater for mammals than for birds.
d. the extinction rate of reptiles is increasing faster than that of amphibians.
2. biologists are studying in an area in virginia that once supported a large elk population. due to over - hunting and loss of habitat, the local elk population disappeared. in response to the local biologists requests, elk from another state were relocated to virginia. after several years, the population has grown in size. now, biologists propose introducing a small population of elk from another state into the area. how will this introduction most likely affect the local elk population?
a. gene flow in the population will cause a significant loss of genetic diversity.
b. genetic diversity will increase in the population and reduce the chances of in - breeding.
c. genetic diversity will not change since elk from the same species are being introduced.
d. interbreeding will introduce harmful genes into the population and reduce genetic diversity.
3. animal populations in the wild have dropped by half over the last 50 years. many of these species are now on the endangered species list. nature preserves are created to help protect these endangered species. ecologists use modern technology to track, observe, and protect these species in the native habitat. select three technologies ecologists can use.
a. drone (unmanned aerial vehicle) patrols
b. satellite imagery from existing satellites
c. wireless wildlife cameras (mounted in the habitat)
d. nature identification (cellular) apps used by visitors
e. trapping and collaring individual animals with gps monitors

Accepted Answer

# Brief Explanations:
1. Analyzing the graph about species extinction rates involves understanding biological trends. For the elk - population question, introducing a new population of the same species will increase genetic diversity through gene - flow. For tracking endangered species, drones can cover large areas, satellite imagery provides a broad - scale view, and wireless wildlife cameras can capture on - the - ground activity.
2. For question 1, without seeing the graph, we can't be sure, but the general topic is species extinction in biology. For question 2, gene flow occurs when individuals move into a population, bringing new alleles and increasing genetic diversity. For question 3, drones, satellite imagery, and wireless wildlife cameras are useful for monitoring animals in their habitats.
# Answer:
1. (No answer can be provided without seeing the graph clearly)
2. b. Genetic diversity will increase in the population
3. a. Drone (unmanned aerial vehicle) patrols, b. Satellite imagery from existing satellites, c. Wireless wildlife cameras (mounted in the habitat)
