Answer:
F2 has 600 tall plants.
Explanation:
According to Mendel's concepts, the F2 generation is formed by crossing two heterozygous plants, that is, two plants with the Aa alleles. These plants have the genes for tall plants and short plants, although they are tall because of the dominant "A" allele. In the cross between these two plants, we will have an offspring formed by 25% of short plants (aa), 25% of hom0zygous tall plants (AA) and 50% of heterozygous tall plants (Aa). As we can see, there are 3 times as many tall plants as short plants in F2's offspring. Therefore, if there are 200 short plants in a population, to know the amount of tall plants, we must multiply this value by 3. By doing this multiplication, we will know that there are 600 tall plants in F2.
The United Nations Conventions on the Law of the Sea (UNCLOS) stipulates that seabed area, which is not within the landmark of any particular country should be regarded as a common natural heritage. Consequently, any mineral found in such an area can be used by anyone.
However, because of the abundant presence of sea area, and the way national boundaries often conflict, coupled with the problem of illegal mining practices, such laws are difficult to enforce, and so these regulations are not standardized yet.
Some possible impacts of ilegal seabed mining are:
1. Destabilisation of oceanic systems.
2. It constitutes danger to the organisms living in the hydrothermal vents.
