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.

Answer:
C. could not provide a mechanism for moving continents
Explanation:
Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents.
Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.
Asymmetric movement of tectonic plates leads to movement of continents and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.
Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.
Gravitational waves are ripples in spacetime. They are created whenever objects with mass move. Hope this helps :)
Answer:
H=1hump
h=2humps
possible genotypes: HH Hh Hh hh... 1/4 chance they produce a camel with 2 humps.
u got to make a punnet 2×2 square. put one parent on top and one on the side. it makes it easier to solve.
