Natural selection involves changes in the genetic makeup of a population over a period of time. The random change of DNA from parent to offspring, called mutations, can help produce variations in offspring. Some
mutations can be helpful, while others can be harmful. In this experiment, students modeled random mutations.
Data was collected to determine if the mutations were helpful or harmful when trying to collect and eat food.
Imagine climate change causes an increase in global temperature, polar ice melts, and sea levels on Earth rise. The
organisms in this study live in a coastal marsh. Global warming has caused flooding and the once marshy habitat is
underwater. Compare and contrast the traits of each group. Which group would most likely survive and reproduce in
this new habitat?
A)
Group A
B)
Group B
Group E
D)
Group H

What word is used to describe differences of individual organisms

Which is the correct first step in finding the area of the base of a cylinder with a volume of 26x cubic meters and a height of 6.5 meters? v=bh 6.5=b(26x) v=bh v=26pi+(6.5) v=bh v=26pi(6.5) v=bh 26pi=b(6.5)

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.
