The correct answer is option D, difficulty of redesigning workable ecosystems
Reason -
The area that was redesigned into an ecosystem actually failed to attract the endangered species of clapper rails in California because of the following two reasons –
a) Failed attempt of restoration of Cord grass ( a tree which is a dominant tree in the nesting habitat of clapper rail) . Even if few such trees were there they could not grow to their full height and thus were incapable of providing adequate nesting cover
b) Due to the lack of predatory insect, some herbivore insect in the ecosystem attacked the green grasses thereby making the nesting inadequate.
The population of jellyfish would increase and the population of killer whales would decrease
<span>All four nucleotides (adenine, guanine, thymine, cytosine) are synthesized in the liver. The nucleotides can be synthesized de novo or recycled through salvage pathways. The synthesis occurs in the cytoplasm of the cell, not within a specific organelle. The components which are used for the nucleotide synthesis are derived from biosynthetic precursors of carbohydrate and amino acid metabolism, and from ammonia and CO2.</span>
The statement 'fish are able to swim faster in a group to avoid being caught by the predator' BEST describes the most likely reason that swimming in a group can help fish avoid a larger predator.
<h3>What is an adaptation?</h3>
An adaptation is an evolutionary strategy to increase the chances of surviving and reproducing in a given environment.
In this case, swimming in a group can minimize friction in the aquatic environment and thus swim faster.
Evolutionary strategies and adaptations may also be individual, but they always have the same objective.
