Answer:
All of these choices are correct.
Explanation:
Transposons are the DNA sequences that can move from one location to another in the genome. The transposon genes are also known as jumping genes.
The C value paradox of the transposable elements depends on the different factors. The transposons can increase their number by copy and paste mechanism. The genes can be controlled by the enzyme transposase and their copies may exist at the different site of the chromosome.
Thus, the correct answer is option (D).
Answer:
Option A, 1/64
Explanation:
The genotype of a carrier female would be Pp
The genotype of a carrier male would be Pp
When these two adults are crossed , the following offspring are produced
Pp x Pp
PP, Pp, Pp, pp
Thus out of four children 3 children have normal phenotype but two are carrier.
So probability of having one normal child (with genotype PP) is 
So the probability of three normal children is

Hence, option A is correct
If there were no decomposer then the waste would just sit there and it wouldn't be released back into the ecosystem, so then producers wouldn't have much nutrients.
