Year after year, Xavier raises a vegetable garden in the same plot of soil. He observes that the plants grow less abundantly from one year to the next, and they produce fewer vegetables. Which of these processes could help explain Xavier's observations?
A. the rate at which soil bacteria perform photosynthesis
B. the rate at which soil bacteria perform denitrification
C. the rate at which soil bacteria perform nitrogen fixation
D. the rate at which soil bacteria perform chemosythesis

Answers

Answer 1

Answer:

C. The rate at which soil bacteria perform nitrogen fixation

Explanation:

Since Xavier is raising vegetables in the same spot year after year it is reasonable to expect that the plants would deplete the soil of its resources. Since the soil doesn't have enough minerals and not enough time for the bacteria to perform nitrogen fixation the plants don't grow at the same rate and numbers that they used to at the beginning.

Answer:

c. have changed the behavior of elk.

Explanation:

Wolves were reintroduced into Yellowstone Park in 1995. Prior to this time, they were a major predator in the park. Their reintroduction after a decade resulted in a change in the behavior of the Elk which now had a large population in the park and appeared in large herds.

The Elk's behavior has also changed as they do not move into farther thickets so as not to be attacked by wolves. Also, they no longer move to open fields where they grazed as herds to avoid being preyed upon by lions. Vegetation is now restored due to this change in behavior of the Elk.

To do this, a mastermix will be created with all the common reagents to ensure easier pipetting, proper mixing, and controlling for variations in pipetting. Create a mastermix for running 8 identical reactions, including one negative control, each with different gDNA templates (7 total gDNA templates).

Answers
