The incident that you would least expect to happen next is Desert sage bush populations grow uncontrollably.
<u>Explanation:</u>
The picture depicts a food chain in the Grand Basin Desert in Nevada. All the animals in the food chain are either prey or predators or both. If A company that makes snakeskin wallets set up a shop in the area, the population of Mojave rattlesnakes will see a decline.
The rattlesnakes preys upon kangaroo rat and jack rabbit indicating that as the rattle snake population declines, the population of kangaroo rat and jack rabbit will increase. Kangaroo rat feeds on desert sage bush.So when their numbers increases, the desert sage bush population will decrease.
Desert sage bush population growing uncontrollably is the least expected possibility.
Answer:
In the first diagram the weakened pathogen (weaker version of the disease) is inserted into the bloodstream.
In the second diagram the antibodies kill the weakened pathogen. When the immune systems encounters a new disease it "remembers it".
This is why in the third diagram, when the "real" pathogen enters the bloodstream the immune system can effectively kill the disease. As the immune system "remembers" how to defeat the weakened version it can more effectively kill the "real" version.
Answer:
The correct answer is -A. producer level.
Explanation:
the first trophic level is the level of photosynthetic organisms they produce their food and energy on their own from the ultimate source of energy, the Sun. This is why they are called producers.
Producers have the most energy in any ecological ecosystem as all other organisms get food from these directly or indirectly. Only 10 percent of total energy is transferred from one trophic level from producers to the next tropic level through consumers of different trophic levels.

<u>Answer:</u>
A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.
<u>Explanation:</u>
Background Knowledge:
DNA contains genes which is a particular segment of DNA. A gene usually has regulatory regions and a structural region.
Promoter: The regulatory region located to the 5 prime end of coding strand of the gene which is called as promoter that controls the binding RNA Polymerase during transcription.
The Terminator is the other regulatory region, located to the 3 prime end of coding strand of the gene. The terminator region causes RNA polymerase to stop transcription.
Structural region is the region present between the promoter and terminator.
Answer of the question is:
A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.
