Why is short-term environmental change more likely to negatively affect a population than a long-term change?

• Animals do not have time to adapt

• Animals always die

• Animals always move away and leave the ecosystem with less biodiversity

• All of the answer choices

A class of science students investigates and records short-term effects of a tornado that destroyed an area near the school. Which change was NOT caused by the tornado?

• Trees were knocked down

• Species of squirrels became extinct

• Flooding damaged dam

• Buildings were destroyed

Plate movement separated species of organisms. This isolation lead to (a)  

• species developing different traits
• species acquiring learned behaviors
• species developing similar traits t
• species inheriting different traits

A particular Arctic climate historically receives snowfall 10 months of the year. Some rabbits in this climate have white fur, while other rabbits have fur that changes color during the warm months. Over time, the area experience less snow, only 6.5 months of the year. Which trait is favorable in this new climate?

• White fur is more favorable because the rabbits spend a majority of the year in snow

• Brown fur is more favorable because the rabbits spend a majority of the year without snow

• Light tan fur is more favorable because the rabbits can blend into any environment

• White fur that changes to brown during the warm months is more favorable because the rabbits can be camouflaged all year long

Match the following statements about artificial reefs with their corresponding effects on the ocean system.

• Effect of potentially increasing human-shark interactions due to habitat creation

• These created habitats could increase the local shark population, which might increase the number of shark attacks on humans

• Consequence of an augmented fish population on coastal fishing activities

• The increased fish population may lead to overfishing on the coasts

• Potential ecological risks from the construction materials of artificial reefs

• Materials within the artificial reef could contain toxins that damage the marine ecosystem

• Positive ecological impact on marine diversity from artificial structures

• There is an increase in biodiversity in the ocean system

How have human activities modified ocean systems?

• Discarded plastics can trap, suffocate, and cause gastrointestinal problems for marine life, resulting in starvation

• Runoff with excessive chemicals can increase nutrients, resulting in more plant growth and reducing the dissolved oxygen content of the water

• Oil from oil spills penetrates the fur and feathers of organisms, causing vulnerability to temperature changes and decreasing buoyancy in water

• All of the answer choices

Match the following explanations with the correct scenario regarding the changes in the numbers of fish caught near the coast of Texas.

• Scenario where the decrease in numbers is due to a reduction in the number of fishermen

• The fish populations are shrinking because of overharvesting

• Scenario where the decrease in numbers is due to the fish relocating

• The fish have adapted and learned to avoid the fishermen's hooks

• Scenario where the decrease in numbers is a result of the fish populations shrinking

• The fish have moved to new locations

• Scenario where the decrease in numbers is because the fish have learned to avoid danger

• There were fewer fishermen in year 3 than in year 1
