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.
Explanation:
Worms are invertebrate animals with bilateral symmetry. Worms have a definite anterior (head) end and a posterior (tail) end. The ventral surface of worms and other organisms is the bottom side of the body, often closest to the ground. The dorsal surface is located on the upper part of the body facing the sky. The lateral surfaces are found on the left and right sides of the body. Figure 3.35 compares bilateral symmetry in a whale shark and a swimming plychaete worm. Organs for sensing light, touch, and smell are concentrated in the heads of worms. They can detect the kinds of environment they encounter by moving in the anterior direction

Answer:
<em>The statement which is not true is C) They can affect males or females</em>
Explanation:
All the chromosomes in a person are known to be autosomal chromosomes except for the sex chromosomes. The sex chromosomes are of two types: Chromosome X and chromosome Y.
Both the sex chromosomes are X in females. Males have one X chromosome and one Y chromosome. The Y chromosome is shorter than the X chromosome. The Y chromosomes occur only in males. Hence, Y- linked disorders will affect only males. These disorders will never occur in females.
