Answer:
The answer is "
"
Explanation:
In this question, the prescribed mutant E. Coli does not express the lacZ gene, so beta-galactosidase doesn't quite exist. Therefore in a particular strain, there is also the potential of lacZ– and that only the genetic makeup indicates its production of lactose. Therefore the above-mentioned option is correct.
High carbon dioxide concentrations make it difficult for marine animals to breathe (to extract oxygen from seawater). This makes it more difficult for these animals to find food, avoid predators, and reproduce. Low oxygen concentrations can have similar effects.
<h3>What is the importance of oxygen for marine animals?</h3>
It is necessary for fish and other aquatic organisms to survive. Because of the aerating action of the wind, oxygen dissolves in surface water.
As a byproduct of aquatic plant photosynthesis, oxygen is also introduced into the water. Fish and other aquatic organisms cannot survive when dissolved oxygen levels fall too low.
High carbon dioxide concentrations make it difficult for marine animals to breathe (to extract oxygen from seawater).
This makes it more difficult for these animals to find food, avoid predators, and reproduce. Low oxygen concentrations can have similar effects.
Thus, these are the effect of high carbon level have the deep ocean.

Compare and contrast up-lifted and fault-block mountains. Describe the mountains that form as a result of hot-spots in Earth's mantle. Features found at divergent boundaries include ocean ridges . ... Volcanoes that form over hot spots are often solitary and far from tectonic plate boundaries.
It was developed by Alfred Wegener around 1912-1915 time frame. He proposed his theory of the "continental drift". He proposed that the continents plowed through crust of ocean basins. He said that the continents look like a puzzle piece to put together. It's very interesting.
Hope this helped :)
