The answer is A.
Glucose in the sealed tube will be used up by the obligate anaerobe bacterium. This is because it is the only environment that satisfies the condition of having no air or oxygen for the organism to survive. The unsealed tube will obviously have air entering and exiting inside and therefore will not be a suitable environment for the organism. The control tube will have no change in color since it is uninoculated or in other words, no organism was put inside of it.
Answer:
A variable is the parameter over which changes can be made and observed so as to determine the outcome of the experiment. ... An independent variable is the one which can be changed or manipulated by the experimenter so as to observe the impact of such change over the dependent variable.
Explanation:
1. constant speed is a steady speed from start to finish, instantaneous is not constant from start to finish.
2. The average speed of the marble is 5 m/s (meters per second).
3. Rider 1 will arrive at the destination before Rider 2.

If the number of blue jays increases, the two likely effects on other populations are both the number of mice and the number of caterpillars will decrease.
<h3>What are two likely effects on other populations due to the increment in Blue jays population?</h3>
- An organism that preys on other species in order to consume them as food is referred to as a predator.
- Prey is a term used to describe an organism that a predator kills.
- An ecosystem's ability to balance an expanding prey population depends on the interaction between predators and their prey.
- Blue jays and crows both rely on mice and caterpillars as food sources, as indicated by the current circumstance.
- Mice, caterpillars, and blue jays are the prey, while crows and crows are the predators. The two prey populations will decline if the number of blue jays rises.
Hence, both the number of mice and the number of caterpillars will likely drop as the number of blue jays rises, having two possible implications on other populations.
