Perlemoen is reasonably
easy to take available of the ocean and do not really required huge and
expensive equipment. The poachers take out millions of rands worth of Perlemoen
with relatively simple and cheap equipment such as wet suites, googles and
flippers. The most expensive equipment they use are their boats and vehicles. In
comparison with the lucrative industry the costs of poaching are low. Perlemoen
are often the smaller, younger abalone of the species that are taken because
they are quite simply and easier to harvest.
1.
The younger perlemoen are found closer to the
shoreline and often bunched together and they can get a whole whack of them at
one spot.
2.
The strandlopers harvested the perlemoen from
the rocks during low tide without the need for diving.

D. Prokaryots do not have any genetic material.
Answer:
a neutral marker
Explanation:
A gene polymorphism can be defined as the existence of two or more variants of the same gene (i.e., alleles). A polymorphism may be a difference of one nucleotide base in DNA (single nucleotide polymorphisms, SNPs) or indels (i.e., insertions and deletions). A gene under selection will have many polymorphisms in its sequence which may lead to convergence and disproportionate divergence among sequences, and thereby will be uninformative to trace the evolutionary history among individuals within a species, population, etc. Conversely, neutral molecular markers exhibit fewer nucleotide differences, it is for that reason that they are commonly used to determine genetic population structure among individuals.
