Is it the theory of evolution or “Lamarckism”
Answer:
The correct answer is: b. lightening of media in the unsealed tube only.
Explanation:
- According to the question, the bacteria can undergo only aerobic respiration, that is it can produce its energy, that is, ATP, or adenosine triphosphate, only in the presence of oxygen.
- The unsealed tube allowed air or oxygen to pass into it which can be used by the bacteria for its respiration. In the process, it will produce acid that will cause the media colour to lighten.
- The sealed tube do not allow any oxygen to pass into it. As the given bacteria can undergo only aerobic respiration but not anaerobic respiration, in absence of oxygen it will not be able to undergo respiration and produce energy and acid. Hence, the media colour will remain unchanged.
- The control tube is used to check the sterility of the media.
Answer:
T ~ True
Explanation:
The neritic zone is the region of shallow water (200 meters depth) above the continental shelf where light penetrates to the sea floor. Due to the abundant supply of sunlight and nutrients in this zone, it is the most productive ocean zone supporting the vast majority of marine life. As a result, many organisms that require light for photosynthesis can live in this zone, including seaweeds and phytoplankton. Most coral reefs are also found in the neritic zone. ... Swimming organisms in the pelagic zone include dolphins, whales, squid, and numerous species of fish adapted to life at different depths.
